PEN HF Filament
SKU: KN-R20
Food Grade FDA 21 CFR 177.1637 l EU 10/2011 l PFAS-free
PEN HF (Polyethylene Naphthalate High-Flow) is a food-contact approved 3D printing material. It is suitable for all food types and food-processing temperature ranges, in accordance with FDA, EU, and Japan food-contact regulations.
It is safe for food contact as printed, no coating or additional surface treatment required. Its low-adsorption surface helps reduce staining, odor retention, and taste carryover between food batches, supporting easy cleaning and consistent hygiene control.
3D printed PEN HF parts remain dimensionally stable under hot-fill food-processing conditions. The material also offers wear resistance comparable to POM, reducing concerns about microplastic release into food. PEN HF is PFAS-free for food-processing teams moving away from PFAS-based materials

Making Biocompatible 3D Printed Parts Shouldn’t Be Complicated
If you’re struggling to make biocompatible 3D printed parts with SLA and DLP,
We know how frustrating that can be.
Print with PEN filament, and the workflow becomes much simpler.
Send your model to the 3D printer, pick up the finished part, inspect it, and move straight to testing.
So you're not left wondering whether the part was washed and cured properly to meet compliance and perform.
Made in Taiwan
Our filament is manufactured in Taiwan, with every step—from extrusion to final packaging—performed in an ISO Class 8 cleanroom.
An air-cooling extrusion system helps minimize contamination risks, while precise diameter control and consistent spooling ensure reliable printing performance.
Our patent-pending spool design helps prevent filament jams and ensures smooth feeding.

CHEMICAL RESISTANCE CHART
We tested this material with different solvents both in our lab and with real customers in the field. Keep in mind that resistance levels can change at different temperatures or when solvents are mixed together. Use this data as a general guide. We regularly update our solvent resistance table as we gather more data, and you can download the complete list below.
