3M™ Scotch-Weld™ CA40H Clear Gel Instant Adhesive – Ideal for 3D Printed Assemblies

Limited Stock- Once it's gone it's gone! (Subscription box surplus only. We will not be restocking this item!)

When your 3D printed parts need more than friction to stay together, 3M CA40H delivers fast, reliable bonding engineered for plastics commonly used in additive manufacturing.

3M™ Scotch-Weld™ CA40H is a high-performance cyanoacrylate adhesive designed to create strong, durable bonds on PLA, PETG, ABS, nylon, and many other plastics used in 3D printing. Its controlled viscosity formulation forms a stable gel-like bond line that stays where you apply it, making it ideal for precision work on small printed components and assemblies.

Unlike thin CA glues that run everywhere, 3M™ Scotch-Weld™ CA40H provides excellent placement control and small gap-filling capability, allowing it to bridge minor imperfections between printed layers or mating surfaces.

Once applied, the adhesive cures rapidly in the presence of trace moisture on surfaces, producing high-strength bonds within seconds and full structural strength within hours.
