E3D-Online Ltd, an获奖总部位于英国的3D打印热台和外围制造商已发布了用于高温3D打印的新产品。
最新版本是E3D努力携带高温工程级的努力的一部分PAEK filament to desktop 3D printers. These efforts have been successful with the help ofvictrex，用于兰开夏郡3D打印的高级聚合物制造商。
PAEK filament has certain temperature requirements which must be maintained during the print. These demands are fulfilled by E3D’s high-temperature 3D printer components, enabling desktop FDM/FFF machines to print with PAEK filament.
High-temperature desktop 3D printer hotend
Desktop FDM/FFF printers are mostly used with PLA (optimal conditions 185°C-205°C) and ABS (230°C). These printers are not designed to operate above 260°C. Therefore, 3D printing PAEK which has an extrusion temperature between 380°C and 430°C is beyond the technical capabilities of such machines.
使用PAEK打印的另一个重要考虑因素是加热床的温度。与PLA和ABS相比，PAEK需要140°C-160˚C加热床，介于40°C-1110°C之间。
Keeping this in mind, E3D’s has developed the high-temperature heater cartridge and the heater bed, which have made PAEK filament printing possible with desktop 3D printers.
加热器块的喷嘴内安装了热台加热器盒。它的功能是加载或启动打印时加热喷嘴。
E3D has designed the heater cartridge with high-gauge silicone fiber wires and ceramic insulation to make sure it withstands extremes of high temperature. A conductive thermal coating also guarantees that the heat is supplied evenly to the hotend.
这些品质使加热器墨盒能够处理高达550°C的温度。
此外，高温温床可防止磁丝翘曲。E3D通过E3D加热的3mm厚的铝床可以在80秒内达到100°C，并在200°C下连续运行。
Currently, the two products are priced:
–高温加热器墨盒: £57.60 (incl. VAT)
–High temperature heated bed: £103-180 (incl. VAT)
PAEK for desktop 3D printers
由于桌面3D打印机无法雷电竞app下载达到高挤压温度，因此他们无法使用Paek或其他工程级细丝打印。
阻止Paek的另一个障碍是高级聚合物3D打印机的成本，例如雷电竞app下载3DGence INDUSTRY F340and最小超级, both priced over £15,000.
But the 3D printing community has responded to such barriers. In 2016, a team of researchers, facilitated by NASA, modified the opensourceLulzbot TAZ 4至3D印刷，带有高温聚合物. Along with other software and hardware modifications, LulzBot’s native hotend was replaced with E3D-v6 1.75 mm Universal. The refashioned printer was capable of printing with PEI (Polyetherimide).
E3D’s partnership with Victrex and the latest release of the high-temperature 3D printer components is another step in the direction of making PAEK affordable and accessible to the desktop 3D printing community.
