PETG 3D Printing Services
Tough, chemical- and moisture-resistant PETG 3D printing for functional brackets, housings and everyday working parts, with instant online quotes and Australia-wide delivery.

The Tough, Reliable All-Rounder
PETG (polyethylene terephthalate glycol) is the workhorse material for strong, functional everyday parts. It sits neatly between easy-to-print PLA and high-performance engineering plastics, giving you real durability, chemical and moisture resistance, and a clean finish without fuss.
At Solidium3D we print PETG for brackets, housings, guards and mechanical parts that need to survive handling, humidity and light loads. Upload your STL for an instant, geometry-based quote and we manufacture locally with fast, reliable turnaround.
Why Choose PETG
A dependable balance of strength, durability and value for functional parts.
Strong & Durable
Excellent layer adhesion and impact resistance for parts that take real-world use.
Chemical Resistant
Shrugs off moisture, many chemicals and diluted acids, ideal for the workshop.
Slight Flexibility
Bends before it breaks, so parts absorb shock instead of snapping.
Good Finish
Semi-gloss surface with a wide colour range, including translucent options.
Weather Tolerant
Handles humidity and outdoor exposure better than PLA.
Cost-Effective
Engineering-grade performance at an everyday price point.
PETG for Functional Parts
PETG is our go-to for functional brackets, enclosures, guards and mounts, parts that need to be tough and dimensionally stable without the print difficulty of ABS.
It resists moisture and many chemicals, making it a smart choice for parts used around water, cleaning agents or the outdoors. Tell us the application and we will tune wall thickness and infill for the right strength.

What PETG Is Best For
Functional Prototypes
Test-fit and validate designs in a tough, real-world material.
Brackets & Mounts
Load-bearing hardware that resists cracking and fatigue.
Enclosures & Housings
Protective cases for electronics and equipment.
Guards & Covers
Durable machine guards and protective covers.
Mechanical Parts
Clips, spacers and fittings that need to flex a little.
Outdoor Fittings
Parts exposed to moisture, humidity and washdowns.
How It Works
From CAD file to finished PETG parts in four simple steps.
Upload STL, OBJ, STEP or STP files to the online quote tool and get an instant, geometry-based price.
Select PETG, pick a colour and set infill and quantity. The price updates live as you configure.
We optimise orientation and settings for strength, print on calibrated machines and inspect every part.
Parts are carefully packed and dispatched Australia-wide, typically within 2 to 5 business days.
Design Tips for PETG Parts
A few small design choices make PETG parts noticeably stronger and cleaner. Keep walls at 1.2 mm or thicker on structural features, add generous fillets on inside corners to spread load, and avoid long unsupported bridges where a slight sag would matter.
PETG has a little natural flex, which is an advantage for snap-fits and clips: give tabs room to bend and they will survive thousands of cycles. For holes and slots that need a precise fit, add 0.2 to 0.3 mm of clearance and tell us the critical dimensions so we can orient the part for accuracy.
Thinking about infill? For most brackets and housings 25 to 40 percent is plenty; going solid only helps parts under heavy sustained load. If you are unsure, send us the application notes with your order and we will tune the settings for you at no extra cost.
Finishing & Post-Processing
Order PETG parts print-ready, or take them further with optional finishing.
Support Removal
Clean removal of support material so parts arrive tidy and ready to use.
Sanding & Smoothing
Knock back layer lines on visible faces for a smoother, more refined look.
Threaded Inserts
Heat-set brass inserts for strong, re-usable fastening in PETG parts.
Drilling & Fitting
Post-drilling and test fitting for holes that need an exact tolerance.
Industries That Choose PETG
PETG's balance of toughness, moisture resistance and price makes it a favourite across many sectors.
Manufacturing
Guards, brackets and fixtures that survive the factory floor.
Food & Beverage
Moisture-tolerant housings and fittings around washdown areas.
Agriculture
Durable outdoor-adjacent parts that handle humidity and knocks.
Electronics
Enclosures and mounts with a clean, semi-gloss finish.
Marine & Outdoor
Water-resistant fittings, clips and covers.
Product Development
Tough functional prototypes that behave like end-use parts.
What to Send Us
- 3D file: STL is preferred; we also accept STEP, STP and OBJ.
- Units & scale: export in millimetres and confirm the part is real-world size.
- Wall thickness: aim for 1.2 mm or more on structural walls.
- Application notes: tell us the loads and environment so we can tune settings.
- Critical dimensions: flag holes and mating faces that need a precise fit.
- Quantity: add quantities in the quote tool for automatic batch pricing.
PETG 3D Printing FAQs
Is PETG strong enough for functional parts?
Yes. PETG has excellent layer adhesion and impact resistance, making it a reliable choice for brackets, housings and everyday mechanical parts.
PETG vs PLA vs ABS, which should I choose?
PLA is best for looks and detail, ABS for heat and post-processing, and PETG for a tough, moisture-resistant all-rounder. Send us your part and we will recommend the right material.
Is PETG water resistant?
PETG resists moisture and humidity well, so it suits parts used around water. Printed parts are water-resistant rather than fully water-tight unless designed and finished for sealing.
What colours can you print in PETG?
A wide range of solid and translucent colours. Tell us your preference when you order and we will confirm availability.
How strong are PETG layer bonds?
PETG is known for excellent layer adhesion, one of the best among common FDM materials, so printed parts stay strong even across layer lines when loaded in awkward directions.
Can PETG be used outdoors?
PETG handles humidity and occasional weather well. For parts permanently exposed to harsh sun we recommend ASA, which adds full UV stability on top of similar strength.
What tolerances can you hold in PETG?
Typically around plus or minus 0.3 mm depending on geometry and orientation. Flag the critical dimensions with your order and we will orient the print to protect them.
How much does PETG printing cost?
Pricing is calculated instantly from your model's geometry, material and quantity. Upload your STL to the quote tool and you will see the exact price in seconds, with no obligation.
