For common on a regular basis use, there’s nothing incorrect with the usual collection of plastics that almost all 3D printer filaments can be found in. PLA, ABS, PETG — they’ve all obtained their place, they usually’re all fairly straightforward to work with. But when you must work with extra unique supplies, you would possibly must go to extremes and modify an off-the-shelf printer for high-temperature work.
For the group led by [Andreas Hagerup Birkelid] on the Norwegian College of Science and Know-how, the usual menu of printer chow wasn’t as much as the roles that they had in thoughts. They needed to print utilizing polyether ether ketone, or PEEK, a high-performance thermoplastic with helpful mechanical and thermal properties, along with chemical resistance. Bother is, the melting level of PEEK is a whopping 343°C (649°F), making it needed to show up the warmth — quite a bit. A typical Creality CR-10 printer was upgraded to resist not solely the five hundred°C max temperature of the brand new sizzling finish and 200° printed mattress, but additionally to outlive working in what quantities to an oven — a balmy 135° in a chamber constituted of IKEA cupboards. That entailed changing plastic components with metallic ones, upgrading belts, pulleys, and wires, and shifting all of the electronics exterior the enclosure. Even the steppers obtained particular therapy, with water cooling to maintain their magnets from reaching the Curie level.
The mods appeared to do the trick, as a result of a Benchy printed in a carbon-fiber PEEK filament got here out fairly good. It looks like an extended solution to go and form of dear — $1,700 for the printer and all of the mods — however if in case you have a must print unique supplies, it’s method cheaper than a commercial high-temp printer.
