FORMLABS ALPHA BLACK RESIN

Formlabs Alpha Black Resin

Matte black general-purpose resin for the Form Studio 1 – fine details, smooth surfaces and durable parts at an average print speed of 40 mm/h.

Aesthetic and functional parts in black

Alpha Black Resin is a versatile SLA resin from Formlabs' Alpha Resin family, developed specifically for the Form Studio 1. It combines crisp details and a rich matte finish with solid mechanical properties: 42 MPa tensile strength and 36% elongation at break. This makes it suitable for presentation-ready concept models, form and fit prototypes, and jigs and fixtures.

Designed for indoor printing

Alpha Resins are formulated with low-odor components. The liquid resin is classified as non-irritating to skin according to OECD 439, reducing risk from accidental skin contact. Post-processed parts meet ISO 10993 requirements for long-term skin contact (more than 30 days). When printed on the Form Studio 1 with VOC Extractor, the printing process is UL GREENGUARD Gold certified – the certification covers the printing process, not just the finished part.

SURFACE & PERFORMANCE

Presentation-ready and accurate

Rich matte color, crisp details and smooth, dimensionally accurate surfaces mean parts are ready to present and assemblies fit together. The average print speed of 40 mm/h at 100 µm layer height applies regardless of part count or size; print settings are tested and validated by Formlabs.

POST-PROCESSING

Wash, dry, optionally post-cure

After printing, parts are washed in clean IPA of at least 90% purity or in Formlabs Resin Washing Solution. For the best surface finish, Formlabs recommends letting them air dry for at least 30 minutes before handling. Post-curing is optional for Alpha Resins but recommended for parts to reach full strength. Validated settings are available for Form Studio Wash+Cure, Form Wash, Form Wash L, Form Cure and Form Cure L.

Typical Applications

Alpha Black Resin suits form and fit prototypes, presentation and concept models, functional assemblies, and jigs and fixtures. Everyday items such as tools, organizers and replacement parts can also be printed. Since post-processed parts are suitable for long-term skin contact, it is also an option for wearables and frequently handled parts.

The black general-purpose resin for the Form Studio 1

Formlabs Alpha Black Resin suits anyone who wants to print aesthetic yet functional parts with a matte finish on the Form Studio 1 – at home, in the office or in the workshop.

Notes on Use

Alpha Black Resin is supported exclusively by the Form Studio 1. The stated material properties apply to parts post-cured for 5 minutes at room temperature in the Form Studio Wash+Cure. *UL GREENGUARD Gold certification applies only when printing on the Form Studio 1 with VOC Extractor. Suitability for skin contact refers to fully post-processed parts. When handling liquid resin and solvents, follow the safety data sheets.
