3D Printing with Binder Jetting

Binder Jetting (BJ) can produce small details in metal with very high detail. The process binds metal powder to the shape of the part and is then sintered into a fully solid metal part without pores. The part is printed on a larger scale and then shrinks to the desired size during the sintering process. The scaling is difficult to get exactly right, which means that this process has a relatively large tolerance range. The result in terms of the material properties is very similar to the properties you get through traditional sintering of metal, but through Binder Jetting you can get completely different types of geometries. After sintering, the 3D printed parts can be polished in various ways to achieve the desired finish. Another method of 3D printing in metal is DMLS.

ESD står för elektrostatisk urladdning (Electrostatic Discharge), vilket är en plötslig överföring av elektricitet mellan två elektriskt laddade objekt orsakad av direkt kontakt eller genom ett elektriskt fält. Detta fenomen kan orsaka skador på elektroniska komponenter och kretsar, eftersom de ofta är känsliga för små laddningar. För att skydda mot ESD-skador används ofta antistatiska material, jordningsmetoder och andra förebyggande åtgärder inom elektronikindustrin.

A CAD program, which stands for "Computer-Aided Design," is an important component when it comes to ordering 3D prints for industrial purposes. CAD programs are specialized software used to create detailed and accurate digital models of objects, components or prototypes. These digital models serve as basic blueprints or designs needed to produce physical objects using 3D printing technology.

.STL (stereolithography) is a file format used to represent 3D geometry, especially surfaces made up of triangles. It is a common format in 3D printing and is used to describe models to be printed in 3D printers.

.STEP (Standard for the Exchange of Product Data) is a standard for exchanging 3D models and product data between different CAD (Computer-Aided Design) programs. It is a common format in industry and is used to transfer detailed 3D models of components and products.
