Longer ePrint: the World's 1st Dual-head Personal UV Printer

Custom printing has always had a barrier: industrial UV printers cost tens of thousands of dollars and fill a room, out of reach for creators and small shops, especially for raised, textured designs. Longer ePrint brings it to the desktop, billed as the world's first dual-head personal UV printer. Dual printheads with 12 ink channels let all six white channels work together in 3D-textured printing, theoretically stacking up to 6× faster than a single white channel. It supports DTF transfer, uses an open ink system without locked consumables, prints on 300+ materials from phone cases to mugs and fabric, and adds AI assistance and auto-cleaning in a compact all-in-one. Launched in November 2025, it drew 1,621 backers and raised $4,294,357, around 8,588% funded.
