3D printer quality appraisal

3D printer is a device that can "print" real three-dimensional objects. It is based on rapid prototyping technology, also known as additive manufacturing. This technology converts bondable materials such as powdered metal or plastic into solid objects by printing layer by layer. The principle of the
3D printer is to decompose the object into many thin layers, and then stack them layer by layer, using different materials, such as plastics, metals, ceramics, sand, etc., to bond the materials together through heating, curing, sintering, etc., to finally form the object. The printing content of a 3D printer can come from a 3D model on a computer or a real object scanned by a 3D scanner. As long as there is data, it can be printed.
In 3D printer quality appraisal cases, Zhongke Testing can provide 3D printer quality appraisal services.
