Resin Types Explained: Standard, Tough, ABS-like and Water-Washable

Resin printing gives you the sharpest detail available from a desktop studio, but "resin" is not one material. The bottle a studio pours into the printer decides whether your miniature snaps when it falls off the shelf or bounces. Here is a plain-language guide to the main resin families and the right one for each kind of order.

How resin printing works, briefly

A resin (SLA or MSLA) printer holds a vat of liquid photopolymer. A screen underneath shines UV light in the shape of each layer, curing it solid, and the build plate lifts the growing part out of the liquid. Layers are typically 0.025 to 0.05 mm thick, which is why resin captures skin texture, chainmail and tiny text that filament printers cannot. After printing, the part is washed to remove uncured resin and then cured under UV light to reach full hardness. For the differences between resin and filament printing, see FDM vs resin.

Standard resin: maximum detail, minimum toughness

Standard resin is the default for miniatures, busts and display figurines. It cures hard, holds the crispest edges and comes in grey (perfect for painting), white, black, clear and a few colours.

The catch is brittleness. Standard resin behaves a bit like hard candy: thin swords, spear tips and outstretched fingers can snap if the model is dropped or handled roughly. For pieces that live in a display cabinet, that is fine. For a miniature that travels to game night every week, it is worth upgrading.

Tough and ABS-like resin: the everyday upgrade

"Tough" and "ABS-like" are marketing names for resins with added flexibility. They bend a little before breaking, roughly like ABS or nylon plastic, and are far more forgiving of drops, thin parts and press-fit assembly.

You give up almost nothing: detail is nearly identical to standard resin, and the surface sands and paints the same way. Prints are slightly less rigid, so very large flat panels can flex, but for figurines, tabletop miniatures, cosplay accessories and functional small parts this is what we usually recommend. Fantasy Lab 3D prints most gaming miniatures in an ABS-like grey for exactly this reason.

Water-washable resin: convenient, with trade-offs

Regular resin must be washed in isopropyl alcohol. Water-washable resin cleans up in plain water, which is easier to handle and less smelly. Detail is comparable to standard resin.

The trade-offs: water-washable resin is generally more brittle than standard and can absorb a little moisture over time, which may cause fine cracks in very thin parts. It is a good choice for solid, chunky pieces and models that will be sealed with primer and paint. It is a less good choice for thin, load-bearing or long-lived outdoor parts.

Specialty resins

Resin	Key property	Typical use
Flexible (rubber-like)	Bends and compresses	Soft grips, seals, wearable pieces
High-temperature	Withstands 150 °C or more	Moulds for small castings, engine-adjacent brackets
Castable	Burns out cleanly	Jewellery masters for lost-wax casting
Clear / transparent	Optically clear after polishing	Lenses, display pieces, light guides
Dental / biocompatible	Certified for mouth contact	Aligner models, surgical guides

Castable resin is what makes 3D printing for jewellery designers possible: the ring is printed, invested in plaster, burned out and cast in silver or gold.

Which resin for your order?

Match the resin to how the object will live:

• Display figurine, bust, statue. Standard or ABS-like grey. Grey shows detail under a lamp and takes primer well.
• Tabletop miniatures that get handled. ABS-like or tough. Thin weapons survive.
• Functional clips, small mechanical parts. Tough. Consider PETG filament if the part is larger than a hand.
• Clear parts, lamps, prototypes of glass items. Clear resin, polished or coated with varnish for full transparency.
• Jewellery masters. Castable resin, sized to allow for metal shrinkage.
• Anything that lives outdoors. Resin is not ideal; UV keeps curing it over years and makes it brittle. Filament is a better fit.

Colour matters less than you might think. Nearly every resin print gets primed and painted, and paint hides the base colour entirely. Choose the resin for its mechanical behaviour and let the finish decide the look.

After the print: washing, curing and safety

Uncured resin is a skin irritant and must be handled with gloves. A good studio washes every part, cures it fully and removes supports before it reaches you, so what you receive is fully hardened, safe to handle and ready for paint. We explain the whole workflow in resin printing after the print.

Fantasy Lab 3D handles all of this in-house. Send us the model and tell us how the piece will be used, and we will choose a resin, print, clean and cure it, and optionally prime or paint it.
