Photopolymer resin (standard, tough, flexible, castable)

Resin for Fine Detail, Smooth Surfaces and Master Patterns

The finest detail and smoothest surface — not for heat, sun or heavy load.

Resin printing cures liquid photopolymer layer by layer with light. The result is detail and surface finish no filament can match: crisp edges, small text, fine features and a surface close to molded straight off the printer. We run standard, tough (ABS-like), flexible and castable resins.

Resin parts are best for things that need to look exact or capture small features: visual prototypes, small precise components, fit checks of small assemblies, master patterns for silicone molding and castable patterns for investment casting.

They are not a substitute for engineering thermoplastics. Standard resins are brittle compared with FDM plastics, most resins soften at fairly low temperatures, and sunlight keeps curing them until they turn brittle. For anything structural, hot or outdoors, we'll recommend an FDM material instead.

Resin in Texas heat

In a closed car in summer

No

Outdoors, year-round

No

Resin is an indoor material. Sunlight and heat both work against it, so in Texas we keep it to prototypes, patterns and parts that live inside.

Where Resin works

  • Visual and presentation prototypes
  • Small precise parts and fine features
  • Master patterns for silicone and urethane casting
  • Castable patterns for investment casting
  • Dental and lab models
  • Fit checks of small assemblies

Where to use something else

  • Outdoor or sun-exposed parts
  • Anything in a hot vehicle
  • Load-bearing or impact-prone parts
  • Large parts — resin build volumes are smaller than FDM

Grades we print

Standard resin

Finest detail for visual parts.

Tough (ABS-like) resin

Less brittle, for parts that get handled.

Flexible resin

Rubber-like detail parts.

Castable resin

Burns out cleanly for investment casting.

Designing parts in Resin

  • Hollowing larger parts (with drain holes) saves resin and cost.
  • Supports leave small marks; tell us which surfaces are cosmetic.
  • Tough (ABS-like) resin is the better choice if the part will be handled or snapped together.

Resin questions

Resin or FDM?

Resin for detail and finish; FDM for strength, heat resistance and size. Many projects use both — a resin visual model and an FDM functional prototype.

Can you print castable patterns?

Yes. Castable resin burns out cleanly for lost-wax and investment casting. We print the pattern; the casting itself is done by your foundry or caster.

Are resin parts biocompatible or food-safe?

Not by default — standard resins are neither. If the application needs a certified material, tell us up front and we'll say plainly whether we can supply one.

Compare with

  • ABS — The classic housing plastic: roughly 85–100 °C heat limit, and it can be vapor-smoothed.
  • PLA — Stiff, accurate and the cheapest to print — but it softens at roughly 50–60 °C.
  • TPU — Flexible and abrasion-resistant — gaskets, bumpers, boots, pads and grips.
  • PLA vs PETG vs ASA vs Nylon

Need a part in Resin — or not sure it's the right one?

Send your file and tell us where the part will live. A person quotes every job, usually within one business day, with a material recommendation if a different one would serve you better.

Heat figures are typical published heat-deflection ranges for common filament grades at low load (0.45 MPa), not measurements of our parts. Real values vary with brand, colour, print orientation, part design and — for nylon — moisture. If a number matters to your application, tell us and we'll talk through margin and testing.
