How to Cure Resin Miniatures Without Ruining Detail
Share
A fresh resin print can look finished right off the build plate, but it is not ready to command an Iron Grin Mob just yet. Knowing how to cure resin miniatures is what turns a tacky, fragile print into a hard, paint-ready figure that survives handling, basing, and long campaigns across the table.
Post-curing is not simply blasting a model with UV until it feels like stone. Too little curing leaves resin soft and potentially unsafe to handle. Too much can make thin blades, goblin spears, and banner poles brittle. The goal is an even, controlled cure that locks in every scar, skull, rivet, and ugly little grin without warping the miniature.
What Curing Actually Does to Resin
UV-printing resin hardens when exposed to ultraviolet light. Your printer begins that process layer by layer, but the miniature needs a final cure after printing and washing to fully strengthen the material. This final exposure improves surface hardness, reduces lingering uncured resin, and prepares the model for primer and paint.
The trade-off is simple: resin is not improved forever by adding more UV. After the model is properly cured, extra exposure can yellow pale resins, flatten fine surface character, and make delicate parts more likely to snap. A hulking 32mm orc body has more margin for error than a dagger-thin sword arm or a spindly Pocket Goblin staff.
Curing also cannot rescue a badly washed print. If liquid resin remains in recesses, around support scars, or inside a hollow model, UV light can harden that residue into glossy lumps and pale crust. The wash comes first. The cure finishes the job.
Before You Cure: Wash and Dry the Miniature
Handle uncured prints with nitrile gloves. Keep food, drinks, and bare skin away from your wash station, and work in a ventilated area. Liquid photopolymer resin is a hobby material, not something to treat casually.
Remove the print from the build plate, then wash it in the cleaning liquid recommended for your resin. Isopropyl alcohol is common, but some water-washable resins require water instead. Follow the resin maker's instructions rather than assuming every bottle follows the same rules.
A two-stage wash produces much cleaner results than one dirty container. The first wash removes most of the resin. The second, cleaner wash reaches the fine detail: chainmail recesses, teeth, armor trim, and the awkward underside of a cloak. Agitate gently. Violent shaking can damage fragile pieces before they are fully cured.
Once washed, let the miniature dry completely before UV curing. This matters more than many hobbyists expect. Alcohol or water trapped in hollows, sockets, or deep texture can leave a white haze after curing. Use a soft air blower, let the model sit in moving air, and inspect it under a bright lamp. It should look dry, not wet or glossy in isolated patches.
Do not pour used resin-contaminated wash liquid down a sink. Let the resin solids cure in sunlight or UV light, filter them out, and dispose of the cured waste according to local regulations. The grimdark belongs on the gaming table, not in the plumbing.
Should You Remove Supports Before Curing?
Usually, yes. Removing supports after washing but before the final cure is easier and leaves cleaner contact points because the resin is still slightly flexible. Clip supports close to the model with flush cutters, then twist only where the connection is very thin. A brute-force pull can tear a crater out of a shoulder pad or break a spear shaft.
There are exceptions. Extremely delicate parts may benefit from a very short initial cure, just enough to firm them up before support removal. If you do this, keep that first cure brief. You still want enough flexibility to trim supports cleanly.
For hollow prints, inspect drain holes before curing. They must be open, clean, and large enough for uncured resin and wash liquid to escape. A sealed hollow miniature can retain liquid resin, which may later crack the model, leak, or create pressure problems. No character, however fearsome, needs a resin-filled belly waiting to betray it.
How to Cure Resin Miniatures Evenly
A dedicated UV curing station is the easiest option. Place the dry miniature inside, ideally on a rotating turntable, and cure it according to the resin manufacturer's recommended range. Many standard 405nm hobby resins cure in a few minutes, but the exact time depends on the resin formula, lamp strength, chamber size, model thickness, and color.
Start conservatively. For a typical 32mm resin miniature, try a short cycle, rotate or reposition it, then repeat if needed. The model should feel dry and firm, with no tackiness. If the surface is clean but slightly flexible, add another brief cycle instead of one long punishment session.
If you do not own a curing station, direct sunlight can work. Put the miniature in a clear container to keep dust off it, rotate it periodically, and watch the heat. Bright summer sun cures quickly, but it can also heat a dark base or large flat piece enough to warp it. Sunlight is cheap and effective, but far less consistent than a controlled chamber.
A handheld UV flashlight is useful for targeted jobs, such as hardening a deep recess, a tiny repair, or a hard-to-reach underside. It is not ideal as the main method for a whole warband because even coverage becomes tedious. Protect your eyes from UV exposure and avoid shining the light directly at reflective surfaces.
Use Water for Tricky Clear Resin and Deep Recesses
For clear resin parts, water curing can reduce the oxygen inhibition that sometimes leaves a tacky surface. Submerge the fully washed and dried part in clear water inside a UV-safe container, then expose it to UV light. The water helps light reach the surface more evenly and can produce a clearer finish.
This technique is useful, not mandatory. It adds another handling step, and you must dry the piece afterward. For opaque gray, black, or colored gaming resin, a regular rotating curing station is usually the cleaner, faster route.
Heat Is the Silent Miniature Killer
UV lamps create heat. So does direct sunlight. Most warped resin horror stories are not caused by UV light alone but by curing for too long in a hot, poorly ventilated space.
Keep your curing area at a moderate room temperature. Avoid leaving models in a sealed car, beside a heater, or under a blazing window for an afternoon. Large thin pieces are especially vulnerable: wings, shields, vehicle panels, long swords, and scenic base elements can soften or bend as they heat.
If a part arrives slightly bent from printing or storage, warm water can help reshape it before the final cure. Dip the affected section in warm, not boiling, water until it becomes pliable. Gently correct the shape, cool it in cold water to set it, then finish curing. Do not try to force cold resin straight. That is how a fine weapon becomes two fine weapon halves.
How to Tell When a Resin Miniature Is Cured
A properly cured miniature feels dry, solid, and consistent across the surface. It should not leave residue on gloves, smell strongly of uncured resin, or flex easily in areas that should be rigid. The color may shift slightly as it cures, depending on the resin.
Do not use hardness alone as the only test. Some flexible or tough resins remain less rigid by design, even when fully cured. In that case, rely on the resin maker's cure guidance, complete washing, and an even cure cycle rather than trying to turn a flexible formula into brittle standard resin.
Watch for warning signs. A sticky surface usually means incomplete washing, insufficient UV exposure, or both. White chalky patches often come from wash liquid or moisture left on the model before curing. Brittle tips and snapped details point toward over-curing, especially if the miniature spent a long time in direct sun.
If you receive a physical resin miniature from Proxy Realms, it has already been washed and post-cured for handling. You can move straight to prep work: inspect for any remaining support marks, wash away handling oils with mild soap and water, let it dry, then prime. Save the UV station for your print-at-home STL warbands and fresh resin experiments.
Prep After Curing
Once the miniature is fully cured, inspect it under strong light. Lightly sand support marks with a fine sanding stick, but go slowly around facial detail, texture, and sharp armor edges. If a small gap needs filling, use a hobby putty or a tiny amount of UV resin cured with a handheld light. Sand the repair only after it is fully hardened.
Then wash the finished piece with mild soap and water to remove dust, dry it thoroughly, and apply a thin primer coat. A heavy primer can bury detail just as effectively as a bad cure. Your 16K-sharp teeth, battered plate, and tiny ammunition belts deserve better.
Treat curing as the final forge step, not an afterthought. A clean wash, a dry model, controlled UV exposure, and a little patience will leave your miniature ready for paint, battle damage, and whatever cursed legend you build around it.
