Resin printing is no longer a one-material hobby. With an LCD printer you can choose everything from a budget-friendly standard resin to a precision castable formula, and the choice changes what you can print and how you finish it. This guide walks through the four most useful resin families and when to reach for each.
The Four Resin Families at a Glance
| Resin | Stiffness | Durability | Surface | Typical Use |
|---|---|---|---|---|
| Standard Lite | Low-medium | Fragile | Smooth | Craft, display, prototyping |
| ABS-Like | Medium | Tougher, wear-resistant | Smooth | Functional parts, snap-fits |
| Tough | Medium | High impact resistance | Matte | Enclosures, clips, jigs |
| Castable | N/A (burn-out) | N/A | Detail-critical | Jewellery & dental casting |
Standard Lite Resin: The Reliable Daily Driver
For most hobbyists, a Standard Lite Resin 1kg is the smart starting point. It is lightweight, inexpensive and prints with a low failure rate on any well-levelled LCD machine. It captures fine detail beautifully, which makes it ideal for miniatures, figurines and decorative pieces where raw impact strength isn't the priority.
When to Upgrade to ABS-Like or Tough
If a part will be handled, snapped together or loaded, move to ABS-like resin. It behaves more like injection-moulded ABS: tougher, less brittle and more resistant to chipping. For parts that take repeated mechanical stress — clips, brackets, tool handles — a tough formula adds impact resistance so threads and thin walls don't crack across layer lines.
Castable Resin: For Jewellery and Dental Work
Castable resins are formulated to burn out cleanly with minimal ash, leaving a smooth, high-gloss cavity after investment casting. They are the go-to for jewellery designers and dental labs that turn a printed master into a metal part. Because detail is critical, castable resins reward slow, well-calibrated exposure.
Choosing by Workflow
- Quick cosplay or display piece → Standard Lite.
- Functional prototype or snap-fit housing → ABS-Like.
- High-stress, repeatedly handled part → Tough.
- Rings, chains or dental casting masters → Castable.
Key Tip: Match the Resin to the Post-Steps
Whatever you choose, finish carefully. Standard resins benefit from 5-10 minutes in a wash bath followed by 2-5 minutes of UV curing; engineering and dental resins often need slightly longer to reach full mechanical strength. Wash station and curing time are just as important as the resin itself.
