Design Guidelines
Minimum Wall Thickness
1.2mm for structural parts, 1mm for non-structural
PETG has excellent layer adhesion but needs adequate thickness
Overhang Angles
Maximum 50° without support
Better overhang performance than PLA due to slower cooling
Shrinkage
Minimal shrinkage and warping
Excellent dimensional stability makes it ideal for mechanical parts
Post-Processing
Can be welded, bent when heated, chemical smoothing
Acetone vapor can smooth surface finish

Frequently Asked Questions
Is PETG food safe?
Yes, PETG is FDA approved for food contact and is commonly used in food packaging. It's an excellent choice for kitchen tools and food containers.
How does PETG handle outdoor conditions?
PETG has good UV resistance and can handle temperature variations well. It's suitable for outdoor applications where PLA would degrade.
How clear is transparent PETG?
Transparent PETG provides good clarity suitable for displays and protective covers, though not as clear as injection-molded plastics.
What's the difference between PETG and PET?
PETG is glycol-modified PET, making it easier to print and process while maintaining the chemical resistance and clarity of PET.
