From STL to Tabletop: JLYPT’s End-to-End Guide
Introduction Tabletop gaming has exploded into a multibillion-dollar market where the difference between victory and defeat can be a 0.1 mm misaligned eyebrow. At JLYPT, we produce 12,000 miniature figures weekly on SLA, MJP, and MJF platforms, everything from 32 mm D&D heroes to 1:72 scale historical tanks. This guide covers the material science, support strategies, post-processing, and three fresh case studies that cut lead time by 60 % and paint-prep labor by 40 %.
Table 1: Miniature Technology Matrix
| Technology | Best Layer (µm) | XY Resolution (µm) | Surface Ra (µm) | Max Batch | Typical Use |
|---|---|---|---|---|---|
| SLA (Next GP-Clear) | 25 | 75 | 0.5 | 1,000 | Hero figures |
| MJP Wax | 16 | 34 | 0.3 | 500 | Master patterns |
| MJF Nylon 12 | 80 | 200 | 6 | 10,000 | Army squads |
| FDM 0.4 mm | 100 | 400 | 4 | 5,000 | Terrain |

- Breakaway density 20 % for MJF, 40 % for SLA.
Workflow Deep-Dive
2.1 Software Stack
- Sculpt: ZBrush → Decimate to < 1 M facets → Magics repair.
- Slice: Lychee (resin), Cura (FDM) with tree supports V2.
2.2 Batch Nesting
