PETG HF is a PETG with an emphasis on stable and fast printing, especially for large models. At HEDRAFT, we use PETG HF for large enclosures, large-scale parts, and series where geometry, repeatability, and lead times are critical.

PETG HF – for large and precise parts

PETG HF is chosen when large parts need to be printed faster and more reliably while maintaining precision. This material is well suited for large-scale parts, series, and projects where repeatability and clean geometry are essential.

Where PETG HF is suitable

• Large housings and casings (machinery, equipment, devices)

• Overall functional parts: panels, covers, protective elements

• Serial production: when dimensional repeatability is important

• Parts with geometric requirements (fittings, matings)

• Projects where deadlines are important (we need to get it done faster without sacrificing quality)

• Large interior elements (technical/utilitarian components)

• Large-format spare parts for repair and modernization

When PETG HF is not the best choice

• Permanent Street/UV - Better than ASA

• Strong heat - better than ABS/ASA/PA

• Maximum rigidity - PETG-CF or PAHT-CF is better

• Flexibility is better than TPU

Why choose PETG HF

• Stable printing on large parts (fewer geometry surprises)

• Good repeatability in the series (identical parts)

• Faster production than conventional PETG modes

• Universal "working" mechanics for functional parts

What we need to know before printing PETG HF

• Dimensions of the part and whether a series is required

• Are there any landing sites and tolerances?

• Operating conditions: indoor/outdoor/humidity

• Will there be heating?

• Is a “showcase” surface necessary or is a technical one sufficient?

Examples of PETG HF products

• Equipment housings and casings

• Large panels and covers

• Serial fasteners/structural elements

• Overall repair parts

Frequently asked questions:

How is PETG HF different from regular PETG?

PETG HF is designed for stable and faster printing, especially on large models and in series where repeatability is important.

Is PETG HF suitable for large parts?

Does PETG HF withstand heat?

If you need maximum rigidity, is PETG HF suitable?

Is PETG HF suitable for outdoor use?

For parts near heat, ABS/ASA/PA is better. PETG HF is a "general-purpose" material at moderate temperatures.

For continuous outdoor use and UV exposure, ASA is better. PETG HF can be used in moderate conditions, but for outdoor use, we select the material according to the intended application.

Yes, this is one of the best options when you need to print a large-sized part with good geometry and predictable results.

If rigidity and geometric stability under load are critical, we often choose PETG-CF or PAHT-CF.
