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。
People without a printer assume it's just for toys. In practice, the most common use is a lot more useful (and sometimes profitable) than that.

People who don't have a printer yet usually assume it's just for printing little figurines. In practice, the most common use is a lot more useful (and sometimes profitable) than that.
This is the use case that saves the most money long-term: a discontinued appliance part, a cabinet latch, a broken bracket — a lot of these already have a free 3D file available, or you can measure and model them from scratch.
Once you get the hang of it, you can sell custom parts (keychains, cake toppers, stands) on local marketplaces. Just make sure to price it properly — power, machine wear and your time all count. Our FDM cost calculator does that math for you.

Far more than toys: home organizers, replacement parts, phone stands, hobby miniatures, personalized gifts, and even extra income selling custom parts.
