Biocompatible 3D Printer Resin for Skin Contact

Looking for a 3D printer resin for parts that touch the skin? At Mr Resin we've put together resins that the manufacturer has tested to ISO 10993 standards for external skin contact once cured: made for cosplay, wearables, grips, handles, jigs and prototypes that get handled every day.

On each product page we list which tests the manufacturer declares (for example ISO 10993-5 / 10993-10 for skin contact) and under what conditions. These are not materials for use in the mouth, implants or food contact. If you're after resins for a dental lab, have a look at our dental resins.

What does "biocompatible" mean for a 3D printing resin?

Biocompatibility isn't a simple yes or no: it depends on what the material has been tested for. ISO 10993 has several parts; for example, ISO 10993-5 covers cytotoxicity and ISO 10993-10 covers skin irritation and sensitisation. A resin that passes these tests is suitable, once properly washed and cured, for parts you touch or wear, but that does not make it suitable for use in the mouth, implants or food contact, which need other tests and certifications.

That's why each product page tells you exactly which tests the manufacturer declares and for what kind of contact.

Recommended uses

Cosplay and wearables: masks, armour, props and parts you wear for hours.

Grips and handles: grips, tool handles and parts you touch every day.

Jigs and prototypes: templates, holders and functional prototypes that get handled all the time.

Home and education: everyday parts, with the peace of mind of a material tested for skin contact.

How to make sure the part is safe

The manufacturer's tests apply to the fully cured and post-processed part. Always follow the manufacturer's guide: wash the part thoroughly (isopropyl alcohol or water, depending on the resin), dry it and post-cure it for the stated time under 405 nm UV light; a wash and cure station helps you do it evenly. A badly cured part can keep liquid resin on the surface, and that can irritate skin. Wear gloves when handling uncured resin.

Printer compatibility

The resins in this category work with 405 nm LCD/MSLA resin 3D printers, and some also with DLP or SLA. Check each product page for the recommended exposure settings and exact compatibility.

What each manufacturer declares

Every manufacturer tests different things, so here's exactly what each one states:

Siraya Tech Blu Lava: according to Siraya, the Blu range passes ISO 10993-5 and ISO 10993-10 for external skin contact, as long as you follow their post-processing guide.

BASF Ultracur3D ST 45: Forward AM has tested it to ISO 10993-5 and ISO 10993-10 for skin contact.

BASF Ultracur3D ST 1400: Forward AM has tested it to ISO 10993-10 (skin irritation and sensitisation).

Liqcreate Bio-Med Clear: according to Liqcreate, parts washed and post-cured with their validated workflow pass ISO 10993-5, ISO 10993-10 and ISO 10993-23, and can be autoclaved. Liqcreate doesn't publish a contact class or duration; if you're making a medical device, registration and liability are on you.

Before using a part in contact with skin, check the product page and follow the manufacturer's post-processing to the letter: the tests only apply to a properly washed and cured part.

What about dental or medical use?

For dental labs we have a dedicated dental resins category: resins for models, orthodontics and castables. They're model and pattern materials, not for intraoral use. Resins for use in the mouth, implants or medical devices need specific certifications (medical device certification, for example) that the resins in this category don't have.

FAQs about resin for skin contact

A resin the manufacturer has tested for safety in a specific type of contact with the body. In this category, that means external contact with the skin once the part is cured.

No. The resins in this category have been tested for skin contact, not for intraoral use, implants or medical devices.

They're parts of the ISO 10993 standard: part 5 assesses cytotoxicity and part 10 skin irritation and sensitisation. Passing them indicates that, under the test conditions and with a properly cured part, the material wasn't cytotoxic, irritating or sensitising.

None of the resins in this category declares EN 71-3, the European toy safety standard, so we don't recommend them for toys. What their manufacturers declare are ISO 10993 tests for skin contact.

Cosplay, wearables, grips, handles, jigs and prototypes that you touch or wear.

No. Safety refers to the part once it's been washed, dried and fully post-cured following the manufacturer's guide.

No. None of these resins is certified for food contact.

Have a look at our dental resins category: there are resins for models, orthodontics and castable patterns. They're model materials, not for use in the mouth.

Yes. Uncured resin can irritate the skin, so wear nitrile gloves and work somewhere well ventilated until the part is cured.

Yes. We ship from Spain to Ireland, Portugal, France, Germany, Italy, Belgium, the Netherlands, Luxembourg, Austria and Denmark, with free shipping on orders over €99. Delivery time depends on the country. Below €99, the cost depends on where it's going and how much it weighs, and you'll see it before you pay.
