Resins for 3D Printing Miniatures.

Frequently asked questions

• Why do swords and spears keep snapping off my 3D printed minis?

  Standard resins are too brittle for thin features and snap under normal handling or shipping. TGM-7 has 61.6% strain at break (ISO 527-5A), so delicate parts flex instead of breaking. Studios that switched to TGM-7 report fewer broken-piece complaints and replacement orders.

  The resin performs consistently across batches, so you can dial in your settings once and trust them on the next order. Removing supports before full post-cure also helps protect fine details.

• How do I get sharper faces and crisper armor detail on my minis?

  For most 28 to 32 mm tabletop minis, 50 µm layers with TGM-7 give clean results on faces, cloth folds, and armor textures. For competition or display work, 25 to 35 µm adds extra sharpness.

  The resin holds fine detail at both layer heights. Check our settings library for starting exposures for your specific printer. For production work, 50 µm is the practical sweet spot because it balances quality and print time.

• Why won't paint stick to my resin minis?

  Paint usually fails to stick because of incomplete post-curing or residue left after washing. Wash thoroughly in IPA, post-cure until the surface is fully non-tacky, and let the print dry for 24 hours before priming.

  TGM-7’s hard surface accepts both spray and brush primers well washed and cured. If paint adhesion fails it means people miss proper post-curing.

• How do I remove supports without damaging fine details?

  Remove supports before post-curing, while the print is still slightly flexible. After full cure the material becomes more brittle and supports are harder to remove cleanly. Use flush cutters for main supports and a sharp hobby knife for small nubs.

  This single workflow change protects a lot of delicate features. Studios doing production work tend to make it standard procedure.

• How many minis can I expect from a 1 kg resin bottle?

  A 1 kg bottle of TGM-7 typically produces 100 to 120 standard 28 to 32 mm minis, depending on geometry and support usage. Run a slicer estimate with your files for the most accurate number for your style of printing.

  Heroes, monsters, and large vehicles use more resin per piece. Rank-and-file infantry pushes the count higher.

• Is TGM-7 worth the higher price?

  For production work or selling minis, the answer is usually yes. Fewer reprints, fewer broken pieces in transit, and consistent settings between bottles tend to recover the price difference quickly.

  For very casual hobby printing, cheaper resins may be acceptable. Once volumes go up or pieces are sold, the lower failure rate makes the difference matter.

• What is the best way to prime and paint TGM-7 prints?

  Wash thoroughly, post-cure until non-tacky, and let the print rest 24 hours before priming. Both spray and brush primers (Citadel, Vallejo, Army Painter) work on the surface after proper preparation.

  A light 400 to 600 grit scuff helps on smooth armor plates. The glossy hard surface holds primer well once the print is fully cured and dry.

• How should I store printed minis long-term?

  Keep printed minis out of direct sunlight and high heat. For display pieces under bright lights, a thin clear varnish helps prevent UV-related brittleness over years.

  Normal indoor storage is fine for gaming minis. For pieces displayed under strong lights for years, a UV-protective clear coat is recommended.
