3-D-printing with high performance materials such as PEEK or PEI has been prohibited to only large corporations due to the need for expensive, proprietary 3-D printers. To print in these materials, the hotend, which melts the polymer for deposition, needs to be able to reach temperatures of over 400℃. Also required for successful printing are; a fully enclosed and heated build chamber, an all metal tool-head, and active machine cooling. These professional machines cost between $10,000 to $250,000 and often need proprietary software to run them. The benefit of 3-D printing on desktop machines is that they have most of the functionality of the professional machines, for less than $1000. What they have lacked up to this point has been the inability to print in high temperature plastics. Many desktop 3-D printers have a maximum temperature of 290℃ because of their temperature sensors, and plastic components on the hotend. They often lack heated chambers and heated build plates as well. | 3-D-printing with high performance materials such as PEEK or PEI has been prohibited to only large corporations due to the need for expensive, proprietary 3-D printers.
