Glueing

3D Gloop

Specialized adhesives formulated for 3D printing materials include PLA Gloop, ABS/ASA Gloop, and PET Gloop, addressing bonding challenges unique to printed components. These products enable molecular-level adhesion by partially dissolving the plastic surface to create seamless welds. While the bottle design may limit access to tight spaces, PLA Gloop demonstrates reliable performance, and PET Gloop proves particularly effective for PET/PETG—materials traditionally difficult to bond. Widely endorsed within the 3D printing community, these adhesives also enhance bed adhesion and surface smoothing when applied sparingly to print surfaces.

Loctite/Gorilla Glue Super Glue Gel

Loctite Super Glue Gel and Gorilla Glue Super Glue Gel remain popular choices for bonding rigid plastics like PLA and ABS. Loctite’s gel formula allows precise application, dries transparent in under a minute, and resists accidental spills. However, residual glue often remains trapped in the bottle’s hard plastic casing, requiring extraction for full utilization. While effective for small or unclampable parts, these adhesives are unsuitable for nylon and may fail under prolonged stress.

Devcon Plastic Welder

Devcon Plastic Welder, a two-part epoxy, creates bonds stronger than the layer adhesion of many printed materials. Suitable for high-stress applications, it requires mixing and curing for 10 minutes (initial hold) and 24 hours (full strength). Though occasional inconsistencies in component flow may occur—potentially due to age or storage conditions—it remains a robust alternative to 3D Gloop for clamped assemblies.

J-B Weld

J-B Weld excels in hybrid bonding, such as adhering plastic components to metal. Its steel-reinforced epoxy forms near-permanent bonds, often necessitating destructive methods (e.g., grinding or melting) for separation. Popular in functional applications like 3D-printed firearms, it cures fully within 12–24 hours and withstands extreme mechanical stress.

Material-Specific Recommendations

• PLA/ABS/PETG: Prioritize 3D Gloop for seamless welds; use super glue gels for quick repairs.

• Nylon: Avoid adhesives—opt for mechanical fasteners (screws, clips) due to poor bonding performance.

• Metal-Plastic Hybrids: J-B Weld ensures durable, load-bearing joints.

Note: Surface preparation (sanding, cleaning) is critical for all adhesives. Test compatibility with coated build plates before full application.
