If you want the best possible quality, you need a 3D printer that can handle engineering-grade materials like PEEK and PEI. You can find that with the Intamsys brand.
The Intamsys Funmat HT Enhanced offers desirable features at a very reasonable price of just below $6,000. There are three other Intamsys 3D printers that are industrial-grade and just as reliable: the Funmat PRO 410 Best Peek 3D Printer, the PRO 610 HT Full-Size 3D Printer and the Funmat Pro 310.
It’s no secret that printing in PEEK is tricky, and other 3D printing brands have been around longer. However, newer manufacturers like Intamsys are setting themselves apart by offering similarly capable printers at lower prices than their more established counterparts.
