\n3D Printer That Prints Metal: Binder Jetting vs SLM, Materials and Price Bands (2026)\n<\/h1>

\nA 3D printer that prints metal is a production machine, not a desktop unit: it either jets binder into a metal powder bed and sinters the green part, or melts each layer with a laser. We build both routes on one open material platform \u2014 7 systems<\/strong>, 30+ qualified alloys<\/strong>, build volumes from 160 \u00d7 65 \u00d7 65 mm \uff5e 800 \u00d7 500 \u00d7 400 mm<\/strong>, and 2026 ex-works prices from about US$120,000 to US$570,000<\/strong>.\n<\/p>

\nWhat a metal 3D printer actually does\n<\/h2>

\nEvery metal 3D printer does the same three things: spreads a thin layer of metal powder, places material only where the part is, and repeats until the build is finished. Where machines differ is how they place the material \u2014 and that decides density, speed, materials and cost per part.\n<\/p>

\n\u30d0\u30a4\u30f3\u30c0\u30fc\u30b8\u30a7\u30c3\u30c6\u30a3\u30f3\u30b0<\/b> prints the whole layer at once with an inkjet head, then sinters the green part in a furnace. SLM<\/b> (selective laser melting) melts the layer point by point with a 500 W fibre laser, producing a fully dense part straight off the plate. A third option, gradient SLM<\/b>, blends two to four powders in one build.\n<\/p>

\nThe difference is not cosmetic. A binder-jetted green part leaves the machine at roughly 67% density \u2014 the furnace is what makes it metal. An SLM part leaves the machine at 99.9% relative density but has to be cut off its supports.\n<\/p>
