Platinum Cure Cast print and bake tips
Before you print
- Settings assume supported prints. With supports, keep the burn in exposure at or under 15 to 20 s.
- If you print directly on the build plate, use a short burn in of about 3 s for 5 layers with 5 transition layers.
Orientation
- Print parts at an angle. Large flat areas facing the plate can cup and leave defects.
- Clear resin can close small holes, most of all holes that run along the Z axis. Orient parts so critical holes do not run straight up.
- Very small columns are hard to hold. If they fail, slow the lift speed, add a short rest and raise the exposure a little.
- Take care with thin walls, which can distort.
Post processing (required)
- Wash thoroughly in IPA.
- Let the part dry completely, overnight or with compressed air and about 3 hours of drying. Parts that are still wet can show surface problems.
- UV cure for 10 to 20 minutes.
- Bake at 275°F (135°C) for 60 to 80 minutes in a dedicated oven or air fryer, never a kitchen oven used for food.
The bake is what lets platinum silicone cure against the printed part. Without it the silicone will stay uncured where it touches the print.
Limits
- Made for open molds used with platinum cure silicone.
- Not recommended for closed or injected molds. In testing, injected silicone stayed uncured even after repeated cure cycles.
