Tis the season to be jolly, join the Wolfpack in a fun 25 Days of Materials 3D printing countdown to Christmas and learn about 25 different materials and their unique properties! The objects to be 3D printed are part of the Advent Calendar/Christmas Tree designed by pleppik. Everyday we will be unveiling a new part of the Advent Calendar and talking about a different special 3D printing material.
Day 5: Toy Train. 3D Printing with PETG
PETG filament is an extra tough 3D print material. This is an extreme high strength filament and can achieve very sturdy and strong prints. It has very low shrinkage, making this perfect for larger flat surfaces. PETG is a perfect alternative to ABS and PLA, offering higher strength, lower shrinkage, and a smoother finish.
Some interesting facts about PETG:
- PETG is short for polyethylene terephthalate glycol-modified, and is a transparent type of Copolyester.
- There is frequently some confusion on the difference between PETG and T-Glase. Technically-speaking both products are PETG, but the difference is tantamount to say, find out more here: http://airwolf3d.com/2015/02/25/t-glase-and-petg/
- PETG is the perfect filament to combine strength and flexibility, which is why it’s used in so many mechanical parts or robotics.
- It has great chemical resistance with good acidic and alkalic resistance.
- The filament is environmentally friendly and recyclable. PETG is known for it’s transparency and clarity.
- PETG is also very nice to make artistic prints like bracelet, rings, collars etc.. You get a nice shiny transparent/see thru look which reflects the light nicely.
3D Printing with PETG: Tips and Tricks
- PETG has a higher melt temperature due to the high strength so we recommend setting you hot end temperature around 230 to 260°C.
- Set your bed temperature at 90°C when 3D printing with PETG.
- Apply one coat of Wolfbite by painting on cold glass with long strokes, covering the Wolfbite is a solution specially engineered to bond PETG and ABS plastic parts directly to a heated glass 3D printing surface without lifting. Once the 3D printed parts have cooled, they will dismount from the printing surface with minimal effort, leaving a clean and smooth bottom surface.
Common applications of PETG
PETG is used in a variety of signage, packaging, industrial and medical applications:
- Medical braces.
- Point-of-purchase and graphic displays.
Did you know?
PETG is FDA compliant, so it can be used in medical and food applications. In medical applications, it stands up to radiation and chemical sterilization techniques without changing color.
