3DXTech MAX-G™ PCTG Engineered USA-Made PCTG Filament — Clearer, Tougher, More Chemical-Resistant Than PETG
The engineering upgrade to PETG — better clarity, chemical & impact resistance.
MAX-G™ PCTG is 3DXTech's engineered PCTG — a durable polyester that prints as easily as PETG but offers improved clarity, chemical resistance, and impact resistance. With low shrinkage and excellent dimensional stability, it's a go-to for demanding engineering parts. Compounded in 3DXTech's 68,000 sq-ft Grand Rapids, Michigan facility, it needs no heated chamber and runs on most open-source desktop printers. Full specifications →

A PETG upgrade — clearer, tougher, and more chemical-resistant.
PCTG and PETG are both glycol-modified polyesters and both are great, easy-printing materials — but PCTG steps up the engineering side. MAX-G™ PCTG offers improved optical clarity, better chemical resistance, and higher impact resistance than standard PETG, with low shrinkage and excellent dimensional stability. It's compounded in the USA into consistent, printable filament that runs on practically any heated-bed printer, needs no enclosure, and needs no hardened nozzle.
Impact resistance and dimensional stability — without the printing headaches.
Durable, dimensionally stable parts from a filament that just prints.
MAX-G™ PCTG stretches to roughly 24% elongation before it breaks and carries an 8 kJ/m² Izod impact strength, so parts flex and absorb impact instead of shattering. Low shrinkage and excellent dimensional stability keep prints true to CAD. And it prints easily on a standard heated bed with a normal brass nozzle — no enclosure, no abrasive fiber, no exotic hotend. That balance of toughness and printability is what makes PCTG a smart upgrade for functional parts you put into service.
Real engineering properties, from a published TDS.
These are 3DXTech's published MAX-G™ PCTG values (TDS v1.0), tested on an open-source FDM/FFF machine with a 0.4 mm nozzle at 0.25 mm layers and 100% infill, ISO methods.
Strength at break (ISO 527) — strong, durable parts that hold up in service.
Stiffness under load (ISO 527) — parts stay dimensionally stable.
Strong in bending (ISO 178) with a 1600 MPa flexural modulus.
High ductility (ISO 527) — parts flex and take impact before they fail.
Notched Izod (ISO 180/A) — genuine impact toughness for functional parts.
Deflection temp at 0.45 MPa (ISO 75) — more heat-tolerant than PLA.
Easy to run — standard nozzle, no enclosure required.
3DXTech's recommended starting conditions. MAX-G™ PCTG is unfilled and non-abrasive, so no hardened nozzle is needed and a heated chamber is not required.
Standard polyester hotend range — no exotic high-temperature hardware required.
A warm bed with a suitable adhesive gives reliable first-layer grip and low warp.
PCTG prints with minimal warping, so an enclosure is optional even on larger parts.
No hardened nozzle needed — unfilled PCTG is non-abrasive, so a standard 0.4 mm brass nozzle is fine.
No special layer-height concerns — runs cleanly across the usual range.
Like all polyesters PCTG is mildly hygroscopic; dry before printing for the best surface and consistency.
From clear parts to functional, chemical-contact components.
Off practically every heated-bed 3D printer.
Print prototypes, fixtures, enclosures, and clear or chemical-contact components.
Because it's tough, chemically resistant, and clearer than PETG, MAX-G™ PCTG is a natural fit for parts that go into service — not just prototypes. Print light-transmitting housings and guards, jigs and fixtures for the shop floor, brackets that need to take a knock, or components that see solvents and cleaners. It prints on the hardware you already own and holds tight dimensional tolerances thanks to its low shrinkage.
Four colors — every one the same engineered blend.
Black, Dark Grey, Natural & White.
Choose your color in the buy-box — the spool preview updates as you pick.
MAX-G™ PCTG ships in four colors, from stealth Black to clean, clear Natural. Every color prints the same engineered blend, so you can standardize your settings and just swap the reel. Need a specific color in bulk? Ask us about case pricing.

FAQ
3DXTech MAX-G PCTG — Common Questions
How is PCTG different from PETG?
PCTG and PETG are both glycol-modified polyesters, but PCTG offers improved optical clarity, better chemical resistance, and higher impact resistance, along with low shrinkage and excellent dimensional stability. It's a more durable, engineering-grade option for demanding parts — while printing just as easily.
Do I need a special printer?
No exotic hardware. You need a printer with a heated bed (70–90°C) and a hotend that reaches 250–270°C. PCTG prints with minimal warping, so an enclosure is not required and a standard brass nozzle is fine.
Do I need a hardened nozzle?
No. Unlike glass- or carbon-fiber filaments, MAX-G™ PCTG is unfilled and non-abrasive, so a standard 0.4 mm brass nozzle prints it without any accelerated wear.
Is it good for chemical-contact parts?
Yes. PCTG has improved chemical resistance versus PETG, making it a good choice for parts exposed to solvents, cleaners, and other chemicals. Confirm compatibility for your specific chemistry.
What colors and sizes are available?
Four colors — Black, Dark Grey, Natural, and White — in 1.75 mm and 2.85 mm, on 750 g, 2 kg, and 2.5 kg reels. Ask us for bulk.
Is it made in the USA?
Yes — 3DXTech manufactures and compounds MAX-G™ PCTG in its 68,000 sq-ft facility in Grand Rapids, Michigan, with published data and lot traceability.
