3d peek12/20/2023 ![]() ![]() Industrial 3D printers like the Apium P220 start at $30,000.īut high-end industrial 3D printers can use even stronger plastics such as polyetherimide (PEI) or members of the polyaryletherketone family (PAEK, PEEK, PEKK). ![]() That puts them on the upper end of what the hobbyist community is generally capable of working with. Not only are the extrusion temperatures of these materials greater than 250 ☌, but an enclosed print chamber is generally recommended for best results. But this is where things start to get tricky. If you need greater durability or higher heat tolerance than PETG offers, you could move on to something like acrylonitrile butadiene styrene (ABS), polycarbonate (PC), or nylon. This material isn’t much more difficult to work with than PLA, but is more durable, can handle higher temperatures, and in general is better suited for mechanical parts. The next step up is usually polyethylene terephthalate glycol (PETG). It’s a fine plastic for prototyping and light duty projects, but it won’t take long for many users to outgrow its capabilities. ![]() The downside is that objects printed in PLA tend to be somewhat brittle and have a low heat tolerance. PLA can be extruded at temperatures as low as 180 ☌, and it’s possible to get good results even without a heated bed. That’s because it’s not only the cheapest material available, but also the easiest to work with. Despite the impressive variety of thermoplastics that can be printed on consumer-level desktop 3D printers, the most commonly used filament is polylactic acid (PLA). ![]()
