PETG 3D printing: tough parts that take a knock, heat and damp
PETG is our standard material next to PLA for everything that has to work rather than just look good: holders, brackets, clips, enclosures and parts in the car, shed or garage. It bends instead of breaking, tolerates more heat than PLA and barely minds moisture. We print PETG in Groningen on our own FDM printers at the same material rate as PLA; upload your file for an instant price indication, or read below when PETG is the right choice and when it is not.

What does PETG 3D printing cost?
In our calculator PETG uses the same material rate per gram as PLA; the price difference comes only from the weight, print time and finishing of your part. The current rates and three example prices are on the cost page, so even without a file you know roughly where a small, medium or large PETG part lands.
PETG prints slightly slower than PLA and more often needs support on overhangs that is harder to remove. That shows in the print time and the finishing line, not in a surcharge.
- Material rate equal to PLA; weight and print time set the price
- Instant estimate through the calculator with your STL, 3MF or OBJ
- Colours in stock by arrangement; black, white and grey as standard
- Collection in Groningen without shipping costs
PLA, PETG or ASA?
Typical values from public datasheets; exact values differ per manufacturer and print setting.
| Property | PLA | PETG | ASA |
|---|---|---|---|
| Heat (glass transition, typical) | about 60 °C | about 75 to 80 °C | about 100 °C |
| Behaviour under overload | snaps, brittle | bends, tough | tough, stiffer than PETG |
| UV and outdoors | discolours and weakens | moderate: occasional outdoor use | good: years outdoors |
| Dimensional accuracy and detail | very good | good | good, prone to warping |
| Price at OmniTechs | standard | standard, same rate as PLA | on request |
Where PETG makes the difference
A dashboard holder in the sun, a bracket carrying something, a clip that opens and closes a hundred times, an enclosure around electronics that gets warm, a part in a damp room. In all those cases PLA is too brittle or too heat-sensitive and PETG is the logical step, without the drawbacks of ABS or nylon.
Design rules for PETG
PETG bonds strongly to support and strings on fast moves; most problems are prevented in the design.
- Wall thickness at least 1.2 mm; 1.6 to 2.0 mm for parts under load
- Avoid overhangs beyond 45 degrees or accept a rougher underside
- Draw holes and fits 0.2 to 0.3 mm larger; PETG shrinks little but flows slightly wider
- Clips and springs: thin, long tabs of 1.2 to 1.6 mm flex best
- Run the layer lines along the direction of the load
Where PETG stops
Above about 75 to 80 degrees PETG softens: not for parts against an engine block or in the dishwasher. For years of sunlight ASA is better; for truly flexible parts TPU; for high stiffness and accuracy indoors PLA stays the cheapest. PETG is not certified for food contact or safety-critical use; we say so honestly in the assessment.
How to order
Upload your file in the calculator and choose PETG; you see weight, print time and a price indication. Note in the remarks what the part is for, so we check print orientation and wall thickness before printing. No file? Send a photo with dimensions or the old part; the first assessment is free.
What to expect
- Print orientation and wall thickness checked against the function you describe
- Standard colours black, white and grey; other colours by arrangement
- A single small part usually within a few working days; the date is in your quote
- Honest advice when ASA, TPU or another process fits better
- Collection in Groningen without shipping costs
Frequently asked questions
Is PETG stronger than PLA?
Not in tensile strength: PLA is slightly stiffer and stronger until it breaks. PETG is tougher: it bends and springs back where PLA snaps. For parts that carry load or get knocked, PETG wins.
Is PETG watertight?
The material itself absorbs little moisture and resists water. Whether a printed part is watertight depends on wall thickness and the number of perimeters; tell us it must be watertight and we print with more walls and higher infill.
Can PETG be used outdoors?
Occasionally and in the shade, yes. For years of sunlight we recommend ASA: PETG slowly discolours and weakens under UV.
Is PETG heat resistant?
It stays in shape up to about 75 to 80 degrees; above that it softens. A car dashboard in the sun can reach that; allow for it or choose ASA.
PETG or ABS?
ABS tolerates more heat but shrinks and warps while printing and smells. PETG prints cleaner and is strong enough for most parts. If you really need more heat resistance, ASA is the modern choice.
Does your part need to flex, take heat or hang outside?
Upload your file and choose PETG, or send a photo with dimensions. We check whether PETG is the right choice and what it costs.
