Sick of Waiting 25 Days? Cut Your RimWorld Biosculpter Times by 70%

Reading time: 25 min Updated: June 2025 Game Version: 1.4+

Introduction

Ever felt your colonists spend forever in the biosculpter pod? You're not alone. This guide shows how to dramatically reduce Biosculpter Pod cycle times and cooldowns in RimWorld – covering vanilla tricks and mods alike. We'll walk through early, mid, and late-game strategies to keep your pawns out of pods and back to work faster. (Spoiler: Clean rooms and clever mods can cut cycle time by over 60%!)

With proper optimization, you can achieve dramatic time reductions – from 25 days down to just 7-8 days!

Quick-Start Tips

If you need fast solutions right now, here's a quick-hit list:

  • 1
    Sterile, Tiny Room = Faster Pod – Build the pod in a small, clean room. Sterile tiles give a +15% speed boost (e.g. 8-day cycle → ~7 days). A 6-tile "mini-room" is ideal (easy to keep spotless). For comprehensive cleaning strategies and room optimization, check our environment beauty guide.
  • 2
    Transhumanist Ideology – If your pawn is a Transhumanist, their cycles are 50% shorter by belief! (They only spend ~4 days on an 8-day cycle). Consider converting key pawns or adopting the Biosculpting: Accelerated precept if it fits your playstyle.
  • 3
    One Pod per Pawn (if possible) – A pod biotunes to whoever uses it, locking out others for 80 days. While tuned, that pawn's future cycles run 25% faster – great, but it means effectively one pod per person for continuous use. Plan to build multiple pods as your colony grows (especially for Transhumanists who demand regular cycles!).
  • 4
    Don't Neglect Nutrition & Power – Each cycle needs 5 nutrition loaded (any food) and 200W power. Keep pods powered and pre-loaded with food so pawns can start cycles immediately (pods glow green when ready). No power = no progress! Learn how to handle power outages in our solar flare survival guide.
  • 5
    Mods Can Help Massively – The Faster Biosculpter Pod mod lets you customize cycle lengths and cooldowns (even remove the 80-day lock). If you're okay "cheating" a bit, it's a one-stop fix. Biosculpter Reworked is another that slashes times to ~1 day.

Why Are Biosculpter Pods So Slow?

Biosculpter pods – introduced with the Ideology DLC – are amazing bio-tech sarcophagi that can heal and rejuvenate colonists. By design, they're not meant to be instant miracle machines. Here's a quick overview of their baseline behavior:

Cycle Types & Lengths

There are four cycle types – Medic, Bioregeneration, Age Reversal, and Pleasure. A typical Age Reversal cycle takes 8 days to reverse 1 year of aging (down from 10 days at release thanks to updates). Others range from 4 days (Pleasure) to 25 days (Bioregeneration for heavy injuries). That's a long time for a pawn to be MIA, especially in the thick of colony life.

Cycle Type Base Time Transhumanist With Sterile Tuned + Sterile + TH
Age Reversal 8 days 4 days 6.8 days 2.6 days
Medic 6 days 3 days 5.1 days 1.95 days
Pleasure 4 days 2 days 3.4 days 1.3 days
Bioregeneration 25 days 12.5 days 21.3 days 8.2 days

Biotuning Cooldown

When a pawn finishes a cycle, the pod becomes biotuned to them. For the next 80 days, only that pawn can use it. This was implemented to prevent easy pod-sharing exploits and encourage investment in multiple pods. The silver lining: a biotuned pod runs 25% faster cycles for that pawn. For example, that 8-day age reversal would drop to 6 days tuned.

Pain Point: It's year 5502, you have one biosculpter, and 5 colonists wanting age reversal. At 8 days each (default), that's 40 days total – over half a year – to give each just -1 year age. By then, the first pawn is nearly due for another reversal! Many players find this unmanageable and seek solutions, either in-game or via mods.

Originally the lock was 60 days with no speed boost – the devs later made it longer but added the speed boost to compensate.

Transhumanist Expectations

If a colonist has the Transhumanist trait or ideology, biosculpters shift from luxury to necessity. Transhumanists cut all cycle times in half (they love technology), but they also expect an age reversal every year after age 25.

  • Missing a yearly treatment gives them a -4 mood (gradually worsening each year missed)
  • Doing it gives a +3 mood boost for a few days

This means in a Transhumanist colony, many pawns will be clamoring for that pod on a schedule – making speed and availability crucial.

Nutrition & Power Costs

Every cycle consumes 5 nutrition worth of food (no matter the cycle length), and the pod draws 200 W while active (50 W on standby). If food isn't loaded before a cycle, pawns will waste time doing so after you activate it.

Power Requirements

Active: 200 W

Standby: 50 W

Nutrition Cost

Per Cycle: 5 nutrition

(any food type, quality doesn't matter)

Also, losing power pauses the cycle timer – so keep those pods juiced, or that 8-day timer might stretch even longer.

In short, vanilla biosculpters are balanced with significant time and usage limitations – they give powerful benefits at the cost of days or even quadrums of pawn downtime. Players often feel this is too slow or restrictive, which is exactly why we're looking at ways to speed things up!

Early-Game: Jumpstarting Biosculpting

In the early game, you might not even have a biosculpter pod yet – and if you do, resources are tight. Here's how to approach biosculpting speed when you're just starting out:

1. Research Biosculpting (if you need it early)

Biosculpter Pods require the Biosculpting research (and a construction skill 8 to build). If your starting colonists include a Transhumanist (or an older colonist ~50+ who you want to rejuvenate soon), prioritize this research.

Pro Tip: A Transhumanist hitting biological age 26 will start taking mood hits if no age reversal is available.

In contrast, a non-transhumanist under age 50 won't need age reversal for a long while – you can delay pods until mid-game for those. Assess your colony's makeup: if nobody urgently needs the pod, focus on more critical tech first (like electricity, defenses, etc.) and come back to biosculpting when luxuries are affordable.

2. Build a "Mini" Biosculpter Room

When you do build your first pod, room design can significantly affect its speed. Biosculpter cycle speed scales with room cleanliness – dirt lowers it, sterile cleanliness raises it (up to +15% speed). The smaller the room, the easier to keep clean.

The absolute smallest functional biosculpter room is 6 tiles: place the pod and build a door right over its interaction spot (the little circle marker). This creates a tiny sealed room just big enough for the pod.

Tiny 6-tile biosculpter pod room with door overlapping the pod's access point

A compact biosculpter "closet" – only 6 tiles! The door is built where the pawn stands to enter the pod, doubling as a wall.

Why go tiny?

  • It saves space and materials, obviously – important early on.
  • A smaller room accumulates less dirt and is quicker to clean. Your pawn will only have ~6 tiles to sweep.
  • You can more easily afford to put down sterile tiles when it's just a few squares. Sterile Material research might or might not be done in early game; if not, even a regularly cleaned wooden floor is fine – just keep blood and dirt out.

Pro-tip: You don't need a sterile tile under the door – the game doesn't count floor under doors for cleanliness, but it does count any dirt there. So if your door is the 7th "tile," don't worry about flooring it with silver; do worry about cleaning footprints off it.

The mini-room trick is especially useful if you have only one pod for multiple people. Since only one pawn can use the pod at a time anyway (and it's locked to them after), there's no need for a large hospital chamber with multiple beds like you would for medical treatment. You can always uninstall or reinstall the pod later if you redesign the base.

3. Plan Around the 80-Day Lock (If Sharing)

In early game, you may have more colonists needing the pod than pods available. This is tricky, because of the 80-day biotuning lock. If Pawn A uses the pod, Pawn B cannot use that same pod until ~3 months pass (or until you decide to wipe the tuning by deconstructing/rebuilding, which costs resources). Here are two approaches early on:

Focus One Pawn at a Time

It might actually be worthwhile to give one pawn multiple cycles in a row, then switch. Since the pod is tuned to Pawn A after one use, Pawn A's subsequent cycles are 25% faster.

You could, for example, put an older colonist through back-to-back age reversals (each 6 days tuned instead of 8) to shave a couple years off quickly, or do an age reversal + a healing cycle consecutively. Meanwhile, other colonists wait their turn. This "batch" approach minimizes retuning downtime.

Accept the Loss and Rebuild

Some players in desperation found it's worth deconstructing the pod to reset tuning so another pawn can use it, even though you lose materials.

Warning: This is costly now – you only get back 25% of resources on deconstruct (devs nerfed this from 50%). One forum user calculated that each such reuse costs ~60 steel + 1 component in lost materials. Early game, that's painful!

Consider this a last resort (or an exploit) – generally, it's more efficient to keep the pod and build a second one when you can.

4. Use Pods for Emergencies

Early on, the Medic cycle (6 days) can cure a pawn's infections or gut worms without needing a high-skill doctor. If a valued colonist is on death's door from disease and you have a biosculpter ready, throwing them in could save their life – effectively trading 6 days of downtime for avoiding a funeral.

Speed Matters in Emergencies

A clean environment will get them healed and out faster, hopefully before a new crisis hits.

Biosculpters also freeze disease progress while active!

Bioregeneration Timing

If you get your hands on Bioregeneration (requires a later research), that 25-day base time is huge.

You'll need two units of Glitterworld medicine for this cycle!

In summary: Early game is about deciding when to invest in a biosculpter and setting it up efficiently if you do. A tiny sterile room and maybe focusing one pawn at a time will give you the best results from the one pod you can afford.

Mid-Game: Optimizing Pod Usage

By mid-game, you likely have a decent economy and a larger colony – maybe you've recruited some new Transhumanists or your originals are hitting their 30s and 40s in age. You might have multiple pawns wanting biosculpting for various reasons. Now the goal is efficiency and throughput: get the most out of each pod, or add more pods, without hogging all your time and resources.

1. Sterile Hospital or Pod Room

At this stage, you should research Sterile Materials if you haven't. Converting the floor of your biosculpter room to sterile tiles provides that nice 115% cleanliness factor, which means cycles finish ~13% faster than normal floors. For detailed flooring strategies and cleaning optimization, see our floor cleaning guide.

Time Savings Example

  • An 8-day job could finish in ~7 days
  • A 25-day regeneration could finish in ~22 days

Those extra days matter when you're counting down to a raid!

Room Design Options

You face a design choice:

  • Multiple pods in one sterile room (less silver cost)
  • Individual mini-rooms (easier to keep perfectly clean)
  • Compromise: 2 pods per small room

Quick tip: You can leave the door held open on these rooms if you want pawns to move in/out faster for loading and cleaning – just be aware an open door means if the room gets dirty, it might spread, and also in an open-door design the room might not count as enclosed for the cleanliness bonus if left open constantly.

2. Increase Pod Count

By mid-game, the best way to get more out of biosculpting is… build more pods. There's no way around it – that 80-day exclusivity is telling you each pod is effectively a personal device.

Pod Assignment Strategy

Aim to have at least enough pods for all your Transhumanist pawns (since they will definitely complain if they can't get their turn). For non-transhumanists, you can have them share a pod or two, but try not to exceed 2-3 people per pod, otherwise someone will always be waiting.

Example: If you have 10 colonists of which 4 are transhumanists and 6 are not, you might build 4 pods (one for each transhumanist to use whenever they want) plus maybe 2 extra that the remaining 6 can share as needed for healing or occasional age tweaks.

Remember, the game actually encourages one pod per person in how the mechanics are balanced. Tynan (the developer) specifically increased the biotuning lock to 80 days to discourage constantly swapping users.

Power Management

Hook pods up to power switches or circuits that you can toggle off when not in use.

Note: If a pod is unpowered, the biotuning lock countdown pauses, so turning them off doesn't help "wait out" the cooldown – but it does save 50 W idle drain each.

Uninstall Extra Pods

You can uninstall (pack up) a pod and store it if you temporarily don't need it, to save space and power.

Uninstalling also pauses the biotuning decay similar to power-off.

By mid-game you probably have spare steel and components from traders or mining, so the material cost of building an extra pod (120 steel, 4 components) is not too bad compared to early game. It's certainly better than the waste of repeatedly deconstructing and rebuilding one pod that some tried earlier.

3. Use Auto Age Reverse (for Transhumanists)

One fantastic QoL improvement added in the 1.3.3159 update was the "Auto age reverse" toggle. On any biotuned pod, you can enable this, and a Transhumanist pawn will automatically enter that pod for an age reversal cycle whenever their year is up and they need it.

Auto age reverse toggle on a biosculpter pod interface

The Auto age reverse toggle in the biosculpter pod interface reduces micromanagement.

Mid-game is when you likely have several transhumanists and keeping track of all their "age reversal due in X days" can be a headache. With auto enabled, they'll take care of it as long as the pod is free and tuned to them.

Caution: Ensure the pod's nutrition is loaded and power is on, or the pawn can't start the cycle even if they want to. They'll generate an alert if they can't path to it or it isn't ready.

Also, make sure you have enough pods that not all transhumanists need age reversal at the exact same time – if two are due the same day and share a pod, one will miss theirs. Staggering when they had their last cycle can help if you're limited on pods.

4. Mid-Game Healing Sprees

With Bioregeneration research unlocked (needs Multi-Analyzer and quite a bit of research), you can heal permanent injuries and even regrow fingers/toes in biosculpters. This is huge, but that 25-day base time is rough – mid-game events are frequent (raids, etc.), and having a key pawn out for nearly a month is risky.

Stacking Speed Factors: Transhumanist + sterile room + tuned pod can cut 25 days down to about 8 days! (Bioregeneration for a transhumanist is 12.5 days base, sterile brings it to ~10.9, and tuned further to ~8.2). That's much more manageable.

If the pawn isn't transhumanist, you might consider converting them or temporarily assigning a transhumanist role if possible, just to get that half-time benefit for the duration of treatment. Otherwise, without ideology help, sterile + tuned brings 25 down to ~18.75 days – still long, but better than 25. Possibly schedule it over a relatively peaceful season (maybe winter when you're less active outside).

Also, mid-game you might come across rare Healer Mech Serum items from quests which instantly heal a permanent injury. Those are like gold – obviously use them for the worst injuries (brain damage, etc.) as a priority. For lesser injuries, you can save serums and use the pod over a week or so; it's cheaper if time allows.

5. Managing Nutrition Efficiently

With more cycles happening, ensure your food logistics are up to the task:

Food Quality Doesn't Matter

The pod doesn't care about food quality or mood effects. You can load raw food or even tainted food with no downside, since the pawn isn't eating it directly.

  • Got a ton of insect meat your colonists hate eating? Slap it in the biosculpter.
  • Nutrient paste surplus? Perfect fuel for the pod.
  • Don't waste fine meals or lavish meals – those are better fed to conscious colonists.

Think of the biosculpter as a big nutrient slurry tank; any calories work.

If nutrition is a bottleneck, consider dedicating a bit of farming to pod food (e.g. a hay crop for kibble, or excess potatoes). But 5 nutrition per 8 days for one pawn is pretty minor in mid-game, especially compared to your colony's overall food use.

Quick calculation: Bioregeneration for 5 different pawns will take 5×5 = 25 nutrition total, which is like ~50 corn.

In summary: By following these mid-game tips – sterile rooms, more pods, automation, and efficient resource use – your biosculpter operations should become smoother and faster. You'll spend less time micromanaging pod cycles and more time enjoying the benefits (healthy, happy, younger pawns).

Late-Game: Biosculpting at Scale

Late game, you might find yourself running something akin to a glitterworld spa for your colonists. If you've embraced biosculpting fully, you could have a dozen pods humming along, keeping everyone forever young and perfectly healed. But late game also means larger raids, bigger crises – you need to keep the colony functional while many are in pods.

1. The Biosculptor Clinic

By now, you likely have one pod per colonist (or close to it). Many players set up a biosculptor clinic or wing – a secured room or building with rows of pods. Ensure this area is well-protected (imagine losing 8 colonists because a stray mortar hit your pod room – yikes!).

Climate Control

Pods don't need a particular temperature to function (unlike hydroponics or plants), but remember that pawns will exit the pod naked.

Make sure the room isn't freezing or they'll come out shivering.

Schedule Staggering

If everyone's on a yearly cycle, half your colony could want age reversal on the same day.

Stagger them – divide pawns into groups and initiate their age reversal cycles in different seasons.

Pro Tip: Keep at least one pod untuned and ready for emergencies. Late game, someone might get an otherwise incurable disease or a brain injury; an untuned Medic or Bioregeneration cycle could save them.

2. Chain-Biosculpting & Min-Maxing

In late game, you have the time and resources to really min-max biosculpting benefits. One approach is chain-biosculpting: focus on one pawn at a time and give them all the cycles they could benefit from in one go.

Example Chain-Biosculpting Schedule

Take a 60-year-old colonist with bad back and scars. Instead of doing one age reversal now, another later, and a healing somewhere in between, just dedicate a season to that pawn:

  1. Run Bioregeneration (fix scars, bad back, etc.)
  2. Immediately do Age Reversal (they'll come out ~2 years younger because one cycle = -1 year, but they didn't age during the prior 20 days in the pod either)
  3. Top it off with a Pleasure cycle for a +15 mood buff lasting 12 days

Because the pod was tuned to them after the first cycle, each subsequent cycle in that chain is 25% faster.

You effectively "batch process" that colonist. This leaves your other colonists free (since only one person is monopolizing one pod for that time). Once done, move to the next pawn that needs intensive treatment.

Side effect: Doing this means some pawns might not use their personal pod for a while. If a pod goes unused for 80 days, it loses its tuning (resets to nobody). That could actually be fine – you might intentionally let a pod detune so someone else can use it if needed.

3. Alternate Methods – Genes and Serums

RimWorld's late game (especially with the Biotech expansion) introduces alternative or complementary ways to handle aging and injury that can reduce reliance on biosculpters:

Genetic Immortality

If you have Biotech and can get (or create) a xenogerm with the Ageless gene, a colonist will stop aging biologically altogether.

No age reversal needed if they don't age! Another option is Slow Aging (half or quarter speed).

Healer Mechanites & Luciferium

Apart from biosculpters, late game has the drug Luciferium which slowly heals permanent injuries (and prevents aging) at the cost of permanent addiction.

It's a dangerous route, but some players joke it's the "late game biosculpter."

Age Reversal Serums

Mods like Amrita – Age Reversing Serum allow you to craft an item to reverse age outside of pods.

It essentially lets a pawn "drink youth potion" over a year to de-age, instead of sitting in a pod.

4. Fun with Overclocking (Mods)

Late game is also when you might say "screw it, I want these pods blazing fast." We'll detail specific mods in the next section, but to mention a late-game use: the Faster Biosculpter Pod mod can be adjusted mid-playthrough.

Custom Balance Ideas

  • Set all cycle times to 1 day just to speed-run your colony's rejuvenation before endgame
  • If you've become ultra-rich, you might set the mod so cycles are 2x faster but consume 10x power as a self-imposed balance
  • Late game colonies can generate massive power (geothermal, nuclear, etc.), so maybe you don't mind pods drawing 2000W if they work twice as fast

The point is, late game you have the freedom to tweak these things without feeling it's too cheaty, because you've essentially "won" economically.

One more late-game tip: Keep an eye on mood. Oddly, being in a biosculpter pod can solve many mood problems (the pawn is basically in stasis, unaware of anything), and they come out with positive buffs. But if half your colony is in pods, the ones outside might get stressed from extra work. Also, when a pawn exits a pod, they get a brief Biosculpting Sickness (like cryptosleep sickness – they'll be woozy for a day, moving and working slow). Plan for that: don't send someone into a pod right before a crucial battle unless absolutely necessary.

Modding for Speed: Best Mods to Accelerate Biosculpters

If vanilla limitations still leave you wanting, the RimWorld modding community has you covered. Several mods directly target biosculpter speed, cooldowns, and convenience. Here are the top picks to consider:

1. Faster Biosculpter Pod (by Inglix)

The all-in-one solution. This mod is basically named after the very thing you're searching for. It adds a mod settings menu where you can customize nearly every aspect of biosculpter pods:

Mod settings for Faster Biosculpter Pod – sliders for cycle durations, biotuning duration, etc.

The Faster Biosculpter Pod mod settings allow you to fine-tune cycle times, biotuning lock duration, and more.

Cycle Duration Sliders

Shorten any cycle type to a fraction of the default. Want age reversal in 2 days instead of 8? Just move the slider.

You can go the other way too (lengthen cycles) if you felt like it, but who would? 😉

Biotuning Cooldown

Hate the 80-day lock? You can reduce it or disable it entirely.

If set to 0, any pawn can use any pod anytime (which is arguably overpowered).

Nutrition & Power Balance

If making cycles super short feels cheat-y, the mod allows you to increase power drain or nutrition required per cycle to compensate.

For instance, you might make cycles 4x faster but demand 4x nutrition each time.

In practice, this mod can trivialize biosculpting if you push everything to the max (imagine 0-day cooldown, 1-day cycles). Many players use it a bit more moderately – e.g., cut all cycle times in half (stacking with transhumanist so it's quarter of original), or reduce biotune to 20 days so one pod can serve 4 people in rotation. It's up to you.

2. Biosculpter Reworked

This mod takes a slightly different approach: rather than giving you sliders, it comes with a rebalanced setup:

Ultra-Fast Cycles

All cycles (Healing, Age, Pleasure) are shortened to 1 day base (or a similar very low number).

Your colonists hop in the pod and come out the next morning all fixed up.

Multi-Year Age Reversal

It includes a setting to adjust how many years get reversed per cycle. In vanilla, one cycle = -1 year.

You could make one cycle reverse 5 years, rejuvenating a 60-year-old to 25 in a little over a week.

Balanced Nutrition

Nutrition costs are scaled down (since cycles are so short, they'd consume a ton of food otherwise).

It may reduce the 5 nutrition cost to something like 1 or 2 per cycle.

This mod is great if you want a plug-and-play buffed biosculpter that feels more like an advanced endgame tech (comparable to healer serums or luciferium in power). It doesn't address the 80-day lock much, but if cycles are a day, sharing pods is less of an issue anyway – you could conceivably cycle 10 pawns through one pod in 10 days!

3. Other Helpful Mods

Biosculpter Pod & Neural Supercharger Resize

A simpler mod that doesn't change mechanics, but reduces the size of biosculpter pods in terms of building footprint.

Makes it easier to fit pods into small rooms or your base layout, which indirectly helps with cleanliness.

Selective Bioregeneration

This mod allows you to choose which injury or condition a pawn's Bioregeneration cycle will heal.

You won't end up wasting a long cycle on a lesser scar when you really wanted that bad back fixed.

Amrita – Age Reversing Serum

Gives a drug approach to age reversal, allowing pawns to slowly reverse age over time with a craftable serum.

An alternative to pods for those who don't want pawns out of commission.

Modder's Note: Making things too easy can reduce the drama RimWorld is known for. Some players install these mods in late-game when the story is winding down, so they can perfect their colony without grind. Others use them from the start to enable a "transhumanist utopia" playthrough. Use mods in the way that keeps the game fun for you – there's no wrong choice in a single-player sandbox!

FAQ: Burning Questions

Let's address some frequently asked questions about speeding up biosculpters and using them effectively:

"Is sterile tiles really worth it? It's only 15% speed boost…"

Answer: Yes – over long cycles, that boost is significant. For a baseline 8-day cycle, 15% saves ~1.2 days. For a 25-day cycle, it saves nearly 4 days. Plus, sterile tiles help prevent infections during regular medical treatments too. They do cost silver, but one 5x5 room's flooring can be obtained from a single silver meteor or trade. Many players consider it essential for any hospital or hi-tech facility. Keep in mind, cleanliness scales linearly – even if you can't get to +0.6 cleanliness (sterile), just keeping dirt out gets you part of that boost. Every little bit helps when you're literally waiting on the clock.

"My pawn came out of the pod and immediately fell over, what happened?"

Answer: They are likely suffering from biosculpting sickness (similar to cryptosleep sickness). Pawns exiting a long biosculpter cycle will be a bit woozy – impaired consciousness and movement for a day or so. This is normal; just give them a bit of time to get back to full strength. It's another reason to not send your whole army into pods right before an attack. If needed, you can administer wake-up or go-juice (if you're okay with drugs) to temporarily counteract the sluggishness, but usually it's fine to let them rest it off. Plan around it by ending cycles at night or when that pawn can afford a day of light duties after.

"What happens if a pawn's age reversal demand timer hits zero and I haven't done it?"

Answer: If they're Transhumanist, they'll get a mood debuff that grows over time: -4 (initially), then -7, then -10 as they get more upset about not being kept young. It caps at -10. They won't die or anything dramatic; it's just a mood thing. If they're that upset and a pod is free, they'll go use it (if auto is toggled on). If you absolutely can't do an age reversal in time, try to offset their mood with other boosts (nice dining room, drugs, etc.) until you can. Non-transhumanist pawns don't "demand" age reversal at all – they might be happier if you make them younger (since they lose some age-related ailments), but there's no built-in mood need for it.

"Can I use someone else's tuned pod if they die or leave?"

Answer: If the pawn associated with a tuned pod is gone, the pod remains biotuned to that (now non-existing) pawn for the remainder of the 80 days. You can't use it until that timer expires or you do the deconstruct/rebuild trick. The game currently doesn't have a way to force-retune a pod manually. Best solution: deconstruct it for materials (accepting the 75% loss) and rebuild a fresh one, or just assign a new pod to the remaining colonist.

"What's the max age reversal I can achieve? Can I make a colonist child-aged?"

Answer: Biosculpters won't reverse age below biological 13 years. So no, you can't turn your 80-year-old into a baby or teenager via pod (and children in RimWorld, if you have Biotech, don't use biosculpters for age reversal – they have growth vats instead). Many players set a goal to maintain key pawns at age ~25 or 30 indefinitely by periodic reversals. Fun fact: You can indefinitely extend a colonist's life with vanilla biosculpters – there's no hidden catch. A 80-year-old can get one year younger each year; effectively they'll hover around that age or slowly decline if you can't keep up, but they'll likely die to other causes before old age thanks to biosculpter. We've effectively cured natural aging at that point!

"Do biosculpters cure diseases like mechanites or resurrection sickness?"

Answer: The Medic cycle will heal one random infectious disease (e.g., malaria, flu) in addition to all fresh wounds. It doesn't target chronic conditions like fibrous mechanites, nor things like resurrection psychosis or dementia. Bioregeneration can heal some chronic stuff (bad back, cataracts, frailty) but not mechanites or gut worms. Biosculpters also do not cure addictions. Essentially, think of them as super-surgeons: great at physical fixes – scars, missing fingers, disease infections – but not a cure-all for every ailment. And no, they can't regrow missing limbs beyond fingers and toes; you'll still need bionics or limb replacements for legs, arms, etc.

Oct 22, 2021 (1.3.3159) Biosculpter Rework: "Biotuned pods now run cycles 25% faster. Biotuning duration increased to 80 days. Added Auto age reverse toggle." Faster for tuned users (e.g., 8d -> 6d). Longer lock discourages swapping, but mitigated by auto-usage and speed boost.
Nov 2022 (1.4 / Biotech) No direct changes to biosculpter, but Biotech added gene aging mods. Indirect: Players gained alternatives (genes to slow/stop aging).
Future Updates (No major changes announced as of 2025.) The mod ecosystem fills the gap for further speed tweaks.
