Phrozen PFA vs FEP: Real Differences for Resin Printing
Phrozen's PFA film (nFEP) has lower surface energy than FEP, reducing peel forces by 15-20%, which improves print success with high-viscosity resins. It costs 2-3x more but lasts 30-50% longer if installed with correct tension.
Anycubic Tool Kit: Buying Guide for Makers
Anycubic Tool Kit: decent entry-level set with essential tools. Weak points: hex driver handles wear out, needles too soft. Brass brush is standout. Worth it for hobbyists, not for heavy daily use.
