Assembling multi-part 3D prints (whether FDM, SLA, or SLS) presents a unique challenge. Unlike traditionally molded parts, 3D prints often have layer lines, minor surface porosity, and deliberate mating tolerances that create small gaps. Furthermore, many common 3D printing plastics like PLA, ABS, and especially high-performance Nylon and Polycarbonate, can be tricky to bond.
You need a fast, high-strength adhesive that delivers a reliable bond across diverse plastic chemistries and can handle the microscopic imperfections inherent in a printed surface.
Don’t let slow-curing epoxies or weak solvent glues bottleneck your rapid prototyping or production assembly process.
INCURE GapFill™ D01 General Purpose Instant Adhesive
The INCURE GapFill™ D01 is a low-viscosity, general-purpose ethyl cyanoacrylate that offers an exceptional balance of speed, strength, and versatility, making it the ideal choice for assembling a wide variety of 3D printed materials. Its low viscosity allows it to wick into fine layer gaps and pores, creating a stronger mechanical lock than high-viscosity gels.
| Feature & Benefit | Technical Insight for 3D Prints | Conversion Value |
| Ultra-Fast Fixture Time | Cures in as little as 5 seconds, which is critical for assembling complex prints where quick alignment and handling are necessary to maintain production speed. | Rapid Prototyping Ready: Go from printing to finished assembly in minutes, not hours. |
| High Shear Strength | Provides a maximum shear strength of 2,900 psi, ensuring the bond line is often stronger than the 3D printed substrate itself, resisting structural failure. | Structural Integrity: Achieve professional-grade, load-bearing joints suitable for final-use parts. |
| Low Viscosity for Wicking | The low-viscosity formula allows the liquid adhesive to be drawn into and fill microscopic gaps and layer lines on the printed surfaces via capillary action. | Fills the Voids: Get a comprehensive, full-surface bond, even with minor surface imperfections typical of 3D prints. |
| Wide Material Compatibility | Bonds effectively to common 3D print materials including PLA, ABS, PETG, and Polycarbonate, as well as other materials you might integrate (e.g., metal inserts). | Universal Tool: Use one adhesive for nearly all the materials in your 3D printing workflow. |
Application Steps: Assembling 3D Printed Components for Peak Strength
1. Preparation (Cleanliness is Key): Thoroughly clean both mating surfaces of the 3D print. Remove all support material residue, dust, or oils (especially from Nylon prints). Use a degreasing solvent (like IPA) and wipe until the surfaces are completely dry. For hard-to-bond plastics (like Polypropylene), an activator/primer may be necessary.
2. Application (Use Sparingly): Apply a very thin, uniform bead of GapFill™ D01 to one side of the joint. Remember, cyanoacrylates cure best in a thin film. Applying too much will slow the cure and weaken the bond.
3. Assembly (Immediate and Firm): Immediately bring the two printed surfaces together and hold firmly for at least 15-30 seconds. This pressure ensures the adhesive spreads uniformly and initiates the ultra-fast cure.
4. Curing Time (Handling Strength): While the parts are fixed quickly, allow a full 24 hours for the assembly to reach its maximum strength before subjecting the part to stress, machining, or heavy loads.
