Troubleshooting: Print-Roller Sinking and Burr
故障：树脂辊压花纹理塌陷与毛边
标签：塌陷,毛边,树脂辊,压深过大,分道辊压
直接用树脂辊压花时花纹肩部塌陷、板面起毛边，多因树脂硬度不足或单道压深过大。对策：单道压深限制在板厚 5% 以内、深纹分两道辊压；小于 0.3 mm 的花纹改由金属辊承担；辊压约 200 次后检查辊面磨损并补固化。边缘毛边用 400 目砂带顺纹理轻磨。
When rolling directly with a resin roller, pattern shoulders sink and the sheet grows burrs—usually from low resin hardness or excessive single-pass depth. Keep single-pass reduction within 5% of sheet thickness and split deep patterns into two passes; shift features under 0.3 mm to a metal roller, and inspect the surface for wear after about 200 passes, re-curing as needed. Trim edge burrs lightly along the grain with 400-grit.
