Photopolymer for MSLA and DLP

Resin for MSLA and DLPDetail you cannot extrude.

Photopolymer resolves features an FDM nozzle cannot reach: 35 micron walls, crisp text, smooth curves. Every ZORVA resin ships with a validated exposure table for common LCD panels.

Grades

The grades in this family.

Print settings and mechanical properties are published per grade. A colour change never alters these numbers.

Precision Resin

A low-shrink model resin for parts where the surface is the deliverable. Crisp text, clean 45-degree overhangs and a validated exposure table for common 8K panels.

Best for

Appearance models and miniatures
Master patterns for moulding
Dimensional test fits

Watch out

Model resins are brittle by design. Do not use them for parts under sustained load.

Tough Resin

An ABS-like photopolymer that bends before it shatters. Snap fits survive assembly, threads survive a screwdriver, and dropped parts survive the floor.

Best for

Functional prototypes with snap fits
Housings and threaded parts
Jigs handled by people

Watch out

Longer exposure and cure than model resin. Under-curing shows up as parts that creep out of tolerance.

High Temp Resin

For fixtures that go near heat: thermoforming moulds, soldering jigs, flow test parts. Heat deflection above 200 °C after a full thermal post-cure.

Best for

Thermoforming and casting moulds
Soldering and reflow fixtures
Airflow and thermal test parts

Watch out

The 200 °C figure needs the thermal post-cure step. Straight out of the UV chamber it is far lower.

Castable Resin

A wax-loaded resin that burns out clean for direct investment casting. Sharp prongs, readable hallmarks, no ash in the flask.

Best for

Jewellery masters and direct casting
Dental and lab models
Fine ornamental work

Watch out

Burnout schedule matters more than print settings. Ramp slowly or the flask cracks.

Questions

Resin, answered.

How long should I cure a resin print?

Wash for 3 minutes in fresh isopropyl alcohol, dry fully, then cure 2–4 minutes in a 405 nm chamber. Over-curing is a real failure mode: it makes parts brittle and yellow, so start short and add time only if the surface stays tacky.

Is 3D printing resin dangerous?

Uncured resin is a skin sensitiser and an aquatic toxin. Nitrile gloves, eye protection, ventilation, and no resin or wash alcohol down the drain. Cured resin and cured waste are inert and can go in normal waste.

Why did my resin print fail halfway up?

Usually suction and supports, not exposure. Large flat cross sections generate enough peel force to tear supports off the plate — tilt the model 20–30 degrees, hollow it with a vent hole, and thicken the support tips before you increase exposure time.
