Next‑gen 3D printing: The Scrap 1 turns metal into precision parts

We have already reported on 3D printers capable of processing not only plastics but also metals. The Scrap 1 from Scrap Labs is one such system. Expanding the range of usable materials should also considerably broaden possible applications — for instance, enabling the production of high-strength replacement parts for heavy-duty machinery. According to the manufacturer, models can be produced from stainless steel, tool steel, and copper and nickel alloys. Cobalt-chrome alloys can also be processed; such materials are commonly used in the medical sector.

What the hot end and heating element do in a conventional 3D printer is replaced in the Scrap 1 by a 200-watt laser operating at 915 nm. However, the operating principle differs significantly from that of conventional 3D printing. Instead of extruding filament layer by layer, the Scrap 1 selectively sinters powder in the build chamber. This laser enables the processing of those metal alloys in the first place. The manufacturer specifies achievable layer thicknesses between 20 and 100 µm, with a laser focus of 0.135 mm and no drift during printing. The printer measures 43 × 50 × 57 centimeters (16.9 × 19.7 × 22.4 inches) and weighs 30 kilograms. The build volume is 100 × 100 × 100 millimeters (3.9 × 3.9 × 3.9 inches), making the system suitable for producing smaller parts. Operation is said to be straightforward, and the printer supports software such as PrusaSlicer. The price starts at $17,990, clearly positioning the Scrap 1 as a professional-grade system.
