The iro3d SPD metal printerThe iro3d selective powder deposition printer is the first high quality low cost metal printer available for $5000 and access to a high temperature furnace or kiln. It works by filling a cruible with sand and metal powder one layer at a time. Metal powder is placed in the shape of the part, while a sand support powder is poured everywhere else. At the top of a part, a long metal powder chimney or runner will be built up from the part. When pouring is completed, an optional shelf and then metal infill and carbon in the form of coke will be placed on the top of the pour on the top of the chimney. A bulbous crucible top will be placed over the crucible, and sand will be added to completely fill the bulbous top. The whole crucible will then be heated in a furnace or kiln to melt the infill metal, which will seep down into the metal powder sections of the pour. After everything cools off, the crucible can be opened, sand and coke poured off, and you will be left with your metal part.
The powders are distinguished between a rough and a fine... (RF and FN respectively.) The rough power may have larger particle size and better thermal conductivity. The amount of fine powder used in a print depends on the surface area of the part. A cube will use less fine powder than a heat sink with fins of the same size. First Order Suggestions:It can be a bit challenging to know what to get for your first order. We are giving some loose suggestions, along with an explaination of what each consumable is used for.
