These beautiful PETG filaments make prints come out with a little "shine" to them. There will be a sparkling feeling under the light. The PETG printer filament is widely used in various mainstream FDM 3D printers, with outstanding comprehensive performance. iSANMATE PETG filaments are very tough and easy to use, which combines the advantages of other filaments such as being safe and odorless; having little shrinkage rate; high impact strength, and good liquidity (flows smoothly). The PETG filament 1.75mm is smooth printing, reducing the odds of failing prints thus reducing waste of time and filament. Advanced laser diameter measuring and self-adaptive control system in the manufacturing ensure these PETG 3D printer filaments of 1.75 mm diameter.
