Short answer

Curing period complete: 10–20 minutes after application.
Maker & casting resin

Cast-and-demold plan

Gel, demold and full cure are separate days

  1. Mix the High impact photoplastic gray, Origin One to ratio and pour
  2. Wait for the demold time
  3. Sand or finish after full cure

This product’s stated stages Quoted at 73°F

  • Curing period10–20 minutes

Worth noticing: The manufacturer states only one timing here (curing period, 10–20 minutes); nothing else is inferred.

Common mistake: Demolding early and leaving a soft, tacky casting that never fully hardens.

About this product

A grey high-impact photoplastic. Its sheet has a wait before the lamp: 60 minutes at room temperature before UV post-curing. The post-cure is then 10 minutes per side under a mercury arc flood or 20 minutes per side under a 405 nm LED.

Using this specific product

Loctite (Henkel) 3D 3172 HDT50 Photoplastic is listed here as the High impact photoplastic gray, Origin One version for 3D printing, impact-resistant parts, and Origin One. For casting resin, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says High impact photoplastic gray, Origin One; related versions can use different timing.
  • For 3D printing, impact-resistant parts, and Origin One, pay particular attention to accurate mixing, mold material, mass and room temperature.
  • Per side. The sheet also lists a 60 minute ambient wait at room temperature before UV post-cure.

How to check readiness

Check the casting itself for flex or tack before demolding. The data sheet lists a UV post-cure of 10 minutes per side under a Dymax 5000 EC Flood and 20 minutes per side under a 405 nm Loctite CL36 LED.

Avoid this mistake

Demold time is not necessarily full mechanical cure.
