Print with Confidence
The Alpha Resin Family uses low-odor components and post-processed parts meet safety requirements for long-term skin contact. Alpha Resins are the first resin printing materials certified for UL GREENGUARD Gold, when printed on Form Studio 1 and using VOC Extractor.
Applications

Concept models and form-and-fit prototypes with smooth, dimensionally accurate surfaces that are display-ready and fit together.

Jigs, fixtures, and structural parts durable enough to tap, screw, and cut.

Functional assemblies that stand up to real world use.

Versatile tools, organizers, and replacement parts with exceptionally smooth surfaces and fine detail.
Resin Printing with Confidence

Low VOC Emissions
The Alpha Resins are the first resin printing materials to achieve UL GREENGUARD Gold*, an independent standard certifying low VOC emissions for homes, offices, schools, and other indoor environments. This certification is for the printing process - not just for a final part.
*when printed on Form Studio 1 using VOC Extractor

Skin-Safe Parts
Post-processed parts meet requirements for long-term (>30 day) skin contact, in accordance with ISO 10993, meaning they can be used in wearables and high-contact applications.

Minimize Risks
Liquid resin scored as non-skin irritant according to OECD 439, a standard commonly used in cosmetics industry, to minimize the risks from incidental skin contact with resin.

Low-Odor Components
Formulated using low-odor chemicals, ensuring a pleasant printing experience.

FAQ
Alpha Grey Resin is a matte grey SLA 3D printing resin in the Formlabs Alpha Resin Family. It combines crisp fine features and smooth, dimensionally accurate surfaces with the durability for functional parts. It's an all-around choice for makers and hobbyists using a desktop 3D printer.
Alpha Grey Resin is well suited for these uses:
- Concept models and form-and-fit prototypes
- Jigs, fixtures, and structural parts
- Functional assemblies
- Tools, organizers, and replacement parts
Yes. Alpha Grey Resin is recommended for jigs, fixtures, and structural parts durable enough to tap, screw, and cut. That makes it practical for home repairs, workshop tools, and parts that need to be assembled with hardware.
Alpha Grey Resin averages 40 mm/h at a 100 μm layer height, regardless of part count or size, without compromising reliability.
Alpha Grey Resin balances speed and aesthetics, like Alpha Black, White, and Clear. Alpha Model Resin offers finer detail at 30 & 50 μm for scale models and figurines. Alpha Fast Resin offers the fastest printing, up to 130 mm/h, for rapid prototyping.
Yes. Alpha Grey Resin uses low-odor components. Alpha Resins are the first resin printing materials certified UL GREENGUARD Gold for low VOC emissions when printed on Form Studio 1 using VOC Extractor. The certification applies to the printing process, not just finished parts.
Post-processed parts meet ISO 10993 requirements for long-term (more than 30 days) skin contact. The liquid resin scored as a non-skin irritant under OECD 439.
Wash parts in clean ≥90% IPA or Formlabs Resin Washing Solution, then air dry for at least 30 minutes before handling. Post-curing is optional but recommended for full strength and functionality. Settings are available for Form Wash+Cure, Form Wash, Form Wash L, and Form Cure units.
Alpha Grey Resin is designed for Form Studio 1.
Post-Processing
Washing
The foundational step in any SLA post-processing workflow is to remove any excess resin on the surface of the parts through a solvent wash.
Use clean ≥ 90% IPA, or use Formlabs Resin Washing Solution.
For the best surface finish, Formlabs recommends allowing parts printed in Alpha Resins to air dry for at least 30 minutes after washing, before handling.
SETTINGS
Curing
Post-curing Alpha Resins is optional, but recommended, for parts to achieve their full strength and functionality. This step completes the chemical reaction initiated during printing, transforming the part from its green state into a fully finished component.
