Model Design
Transform the built 3D digital model into the walking path and extrusion amount that can be recognized by the 3D printer. First, load the model you want to print into the slicing software, and click model slicing. After slicing, send the file to the 3D printer.

3D Printing
Based on PEP technology, metal & ceramic pellets are fused and extruded through UPRISE 3D printers, and are printed and formed layer by layer. The printed products are called "green parts", and two subsequent procedures of debinding and sintering are needed to obtain the final densified metal & ceramic products.

Debinding
The debinding process is to soak the printed product (green parts) in a specific solution and heat it for a certain period of time. Most of the polymer binder in the green parts produce chemical reaction with solution to produce gas and then remove it. The debinded parts are also called "brown parts".

Sintering
Sintering is a process of the contraction of the manufactured parts and the final densification caused by the increase of the contact area between powder particles and the decrease of the void volume through high temperature treatment. The purpose of sintering is to adjust the properties of the parts, from porous degreasing state to non-porous material properties.
