Today, there are binder jetting applications in several industries, and you can create everything from metal parts to large sand-casting cores to full-color prototypes. As a result, the build volume of Binder Jetting machines are amongst the largest compared to all 3D printing technologies (up to 2200 x 1200 x 600 mm). This means that the parts can be "stacked" in the build box. The sintering causes a shrinkage of the part, that is to say a reduction in volume of more than 40%. What are the advantages of the metal binder jetting (mbj) process? In addition, those materials that require post processing can shrink as a result (see disadvantages above), although this shrinkage is often taken into account during the build stage. is cost-competitive to casting. Vat polymerisation uses a vat of liquid photopolymer resin, out of which the model is constructed layer by layer. The same printing method applies as with full color sand printing. The printhead strategically drops binder into the powder. These molds are created and then cast, before being broken apart so the metal part inside can be removed. Sand: 800 x 500 x 400 (up to 2200 x 1200 x 600 mm), Metal: 35 - 50 m As the process uses liquid to form objects . Full colour models typically use a 100 micron layer height while metal parts use a layer height of just 50 microns. AM methods usually impose restrictions on: Wall thickness. It differs from other 3D printing technologies by several advantages. Not only does this remove the need for post-processing to remove supports, but also allows for parts to be positioned so as to maximise build volume. To produce full-color prints, a CAD model that contains the color information must be provided. The type of binder used depends on the type of powder or system that is being used or customer application requirements.
