Proper Handling of UV Curable 3D Printing Resins

Ultraviolet (UV) curable resins for 3D printing/additive manufacturing cure rapidly when exposed to UV light. As with all chemicals, UV curable resins must be handled in a safe manner. This fact sheet is meant as a general guideline for the handling of UV curable resin materials (photopolymers) used in 3D printing systems such as stereolithography (SLA), digital light processing (DLP) and UV inkjet.

PAMA Webinar: Fire Testing and Flammability in Photopolymer Additive Manufacturing, April 11, 2023

April 11, 2023, 1:00 PM – 2:00 PM EDT :: The on-demand ideal of additive manufacturing requires versatile feedstock materials to meet the needs of a variety of industries. Flammability requirements vary widely from industry-to-industry, making the ideal of a universal “fire safe” photopolymer resin challenging to attain. This webinar will present an overview of the ubiquitous UL-94 flammability test, as well as an overview of the requirements for the most common tests in the aerospace and automotive industry where photopolymer additive manufacturing promises to have its greatest impact. Additionally, use of the unique architectures enabled by additive manufacturing to create flame retardant metamaterials will be discussed to highlight a potential future direction for fire-safe photopolymer materials.

Announcing the first PAMA "mini" magazine, December 22, 2022

December 2022

PAMA was formed as a collaboration between the National Institutes of Standards and Technology (NIST) and RadTech, a nonprofit trade association, as additive manufacturing (AM) begins to accelerate on its journey into the manufacturing supply chain. PAMA doesn’t necessarily target specific industries, but instead is a multi-stakeholder organization which spans across the length of the entire AM supply chain (i.e., chemical producers, resin formulators, hardware OEMs, print shops, end-users/customers) and across multiple industry verticals (aerospace, automotive, dental, medical device, construction materials, etc.).

PAMA Webinar: Working Safely with Resin-based Additive Manufacturing Machines, January 24, 2023

January 24, 2023, 2:00 PM – 3:00 PM EST :: Resin-based additive manufacturing processes such as vat photopolymerization and material jetting involve curing liquid resins to build objects. Feedstock resins for these processes can contain chemicals that are known lung or skin irritants and/or sensitizers. This webinar will present an overview of potential adverse health effects from exposure to resin constituents, review current research to understand if and how users might be exposed to resin constituents and to what extent, and describe pragmatic approaches to minimize exposure potential.
