Supplies for 3D printers are PLA、ABS、Photosensitive resin (liquid)、wax-based material、nylon powder、gypsum-like powder、metal powder(Including stainless steel、titanium alloys、cobalt-chromium alloys、etc)。Photosensitive resin, a wax-based material or the like。There are many kinds of 3D printing consumable materials,The melting point, hardness, and strength of each material are different. Different 3D printers use different materials for printing,In general,3D printer is currently printing costs generally higher。In general, FDM technology uses more PLA and ABS；Photo-curing molding using more photosensitive resin or wax-based materials；The use of nylon powder and metal powder laser sintering more；Overall, all belong to additive manufacturing。
Although there are many kinds of 3D printing consumables,PLA is most commonly used at present,PLA is a polymer material synthesized from corn starch,which is more environmentally friendly than the original ABS material,and there is no irritating odor during the printing process。And PLA material is a degradable environmental protection material。
　　3D printing consumables technology is a kind of rapid prototyping technology,It uses adhesive materials such as powdered metal or plastic,Through layer after layer of multi-layer printing method,To construct zero objects。Mold manufacturing and industrial design often use this technology for building models, and now it is developing in the direction of product manufacturing to form "direct digital manufacturing."。
