Alpha Clear Resin (Form Studio 1) 1 L

Alpha Clear Resin is a versatile transparent 3D printing resin for aesthetic, functional parts, combining an optically clear, neutral-colour appearance with fast print speeds and superior mechanical properties.

Formlabs Alpha Clear Resin 1 L cartridge for Form Studio 1

Create transparent enclosures, lighting prototypes and moulds that exceed the strength and toughness of comparable ABS-like resins, with a surface quality that rivals acrylic.

The Alpha Resin family uses low-odour components, post-processed parts meet safety requirements for long-term skin contact, and Alpha Resins are the first 3D printing materials certified UL GREENGUARD Gold when printed on Form Studio 1 with the VOC Extractor.

Form Studio 1 only. Alpha Resins are not compatible with Form 4, Form 4B, Form 4L or Form 4BL.

Resin printing with confidence

 
Low VOC emissions
Alpha Resins are the first resin printing materials to achieve UL GREENGUARD Gold, an independent standard certifying low VOC emissions for homes, offices and schools, when printed on Form Studio 1 with the VOC Extractor. The certification covers the printing process, not just the finished part.
Skin-safe parts
Post-processed parts meet ISO 10993 requirements for long-term (more than 30 day) skin contact, so they suit wearables and high-contact applications.
Minimise risks
The liquid resin scored as a non-skin irritant under OECD 439, a standard commonly used in the cosmetics industry, to minimise risks from incidental contact.
Low-odour components
Formulated with low-odour chemicals for a more pleasant printing experience.
