Apium P220: The Industrial PEEK Printer, Explained
Apium's P220 prints PEEK, PEKK, and ULTEM with a patent-pending adaptive heating system instead of a conventional heated chamber, claiming 29-32% crystallinity without post-print annealing. Here's how the German machine works, what it costs, and how it stacks up against Intamsys, miniFactory, and Stratasys.
