HeyGears PAU20 Black 1kg — PC-Like Tooling Resin

HeyGears UltraPrint-Tooling PAU20 — Black, 1 kg

PAU20 is the polycarbonate-like tooling resin. It is built to carry load: jigs, fixtures, structural brackets and tooling that go into real production rather than a display cabinet. It prints accurately, comes out smooth, and its wear resistance means a fixture still fits the hundredth part as well as it fitted the first.

Who is it for?

Jigs and fixtures – workshop tooling that has to hold tolerance run after run.
Structural components – brackets and mounts that carry a real load.
End-use tooling – parts that go on the production line, not on a shelf.
Engineering prototypes where stiffness matters more than looks.

Why people choose it

High load-bearing capacity – polycarbonate-like stiffness.
Exceptional wear resistance – contact surfaces stay accurate.
Accurate printing with a smooth finish straight off the plate.
Made for final use, not just for looks-like models.

Which printers can use it?

UltraCraft Reflex, Reflex Turbo, Reflex 2, Reflex 2 Pro This resin requires the Pulsing Release Module kit — it will not print reliably without it.

Good to know before you print

Shake the bottle well before pouring; pigment settles.
Wash in 95% IPA, then UV-cure. Short, even cure times keep fine detail from going chalky.
Store closed, upright, dark and dry at room temperature.
Wear nitrile gloves and work in a ventilated space while the resin is liquid.

Common questions

Which HeyGears printers can I use it with?

It is officially supported on UltraCraft Reflex, Reflex Turbo, Reflex 2, Reflex 2 Pro. This resin requires the Pulsing Release Module kit — it will not print reliably without it.

What is PAU20 for?

Tooling. Jigs, fixtures, structural brackets, mounts and any part that has to carry a load or stay dimensionally honest while it is used. It behaves like polycarbonate: stiff, high load-bearing and very wear resistant, so contact surfaces do not wander after repeated use.

Do I need the Pulsing Release Module?

Yes. PAU20 requires the UltraCraft Pulsing Release Module kit — it will not print reliably without it. If you do not have one yet, ask us and we will check which module version fits your printer.

How do I wash and cure it?

Wash in 95% IPA — about 2 minutes rough wash plus 1 minute fine wash in an UltraCraft Wash at 180 r/min — then dry-cure for roughly 30 minutes in an UltraCraft Cure. Short, even curing keeps fine detail from going chalky.

How should I store it, and is it safe to handle?

Keep the bottle closed, upright, dark and dry at room temperature, and shake it well before every pour because the pigment settles. Unopened bottles keep for about 12 months from the production date on the label. Liquid resin irritates skin, so wear nitrile gloves and eye protection and work in a ventilated space. Fully cured parts are safe to handle.

What 3D-printing resin is · Tooling Resin

Resin is a light-sensitive liquid that an LCD/MSLA or SLA printer cures layer by layer with 405 nm light. It gives far finer detail and smoother surfaces than filament, which is why it is the standard for figures, jewellery and dental work.

What it is good for

Standard resin suits models and figures; ABS-like resin is tougher for functional parts; water-washable resin is the convenient choice at home; flexible, high-temperature, castable and dental lines are specialist materials chosen per job.

Which printer

Use a resin printer whose screen size and resolution match the part — ELEGOO Mars and Saturn series for general work, Formlabs or HeyGears professional machines for dental and engineering parts. Take exposure settings from the printer's profile for the resin brand.

Storage and care

Wear nitrile gloves and work with ventilation. Wash parts in IPA or water as the resin type requires, then cure fully under UV. Store resin in its opaque bottle away from sunlight and heat.
