PETG for 3D printing material
The research and application of 3D printing material is very important to 3D printing industry. PETG has various advantages as 3D printing material:
- Biodegradable
- Good toughness and chemical resistance
- No smell during printing process
- Can be used for transparent articles.
- Good processability when be made of linear material. Easy formation, no curl and bending, no deformation.
