层高如何影响3D打印的强度
了解层高如何影响FDM 3D打印的机械强度，并学习如何优化设置以获得更好的结果。
One of the biggest mistakes beginners make when selling parts is looking only at the filament spool price. The real cost goes far beyond.
What makes up the cost
- Material actually used in the part.
- Energy: power × time × price per kWh.
- Depreciation of the machine per hour.
- Consumables and a reserve for failures.
- Labor for setup and post-processing.
Filament vs. resin, in practice
A consistent, quality filament avoids rework — which is what eats margins the most. Two references we use for pricing: Bambu Lab PLA Lite for FDM and ELEGOO Resin 2.0 for fine-detail work.
