What do we know about Bambu Lab's next 3D printer? Not much, but the company has apparently left us a few breadcrumbs. Photos from certification filings reveal the P3C, a seemingly compact, enclosed P-series 3D printer with what looks like a seven-head tool-changing system. Think P2S, but with a serious case of multiple personalities. Pricing and launch timing remain a mystery. Seven heads are better than one, but none of them is talking.
