Ha van egy probléma az újraprasztással, ez az izzószál rovására. Sure, there’s likewise the computationally difficult issue of slicing 3D models, however a 5 to 10 times markup on turning plastic pellets into filament is the biggest problem. It’s even a bigger issue than the issues of compatibility as well as interchangeable parts that includes everybody forking a ‘standard’ printer style lots of times. The expense of filament, though, is the biggest problem, right up there with RepRap designers focusing almost completely on different printer styles instead of the software, firmware, as well as electronics that are likewise vitally important to the RepRap project.
Nearly a year ago, we caught wind of a competition to produce a home-based filament producing station that takes inexpensive plastic pellets offered for about $5/kg as well as turns them in to 3D printer filament that usually offers for $50/kg. Végül bejelentették a versenyt. A győztes, [Hugh Lyman] csak 40 000 dollárt nyert a házszálas fejlesztő állomásának, a Lyman filament extrudernek
The goal of the Desktop factory Competition was to produce a machine that creates filament appropriate for 3D printers with a overall develop expense of under $250 USD. [Lyman] Elégedett azzal a céllal, hogy néhány motort, 3D nyomtatott részeket, PID-vezérlőt, valamint a polc auger fúrócseréjét (ez a tényleges kialakítás, valamint az általa használt szállító, az általa használt módon), amely megbízhatóan elfojtható Műanyag izzószál.
If you want to develop your own Lyman Extruder, all the plans are up on Thingiverse, however LulzBot, the incredible people who provided us a 3D printer, hope to offer a pre-assembled version of this extruder sometime in the future, ideally with a Láncvédő a lánckerék körül.
