Custom Plastic Parts Houston, TX
When you need a custom plastic part that doesn’t exist off the shelf, Spline Arc delivers. We provide custom plastic parts manufacturing in Houston using industrial-grade 3D printing, producing functional components that match or exceed the performance of injection-molded equivalents for small quantities. From one-off prototypes to production runs of 500 parts, we produce custom plastic components without tooling costs or minimum order requirements.

Custom Plastic Parts We Produce
3D Printing Services Houston
Replacement and Discontinued Parts
When OEM parts are discontinued, backordered, or priced unreasonably, we reverse engineer and produce custom replacements. Our process includes 3D scanning the original part, modeling the geometry, and printing in a material that matches or exceeds the original properties. This is ideal for legacy equipment, imported machinery with no local support, and obsolete components.
Custom Brackets and Mounts
Every assembly needs custom brackets, adapters, and mounting plates that don’t exist commercially. We design and print structural brackets, sensor mounts, panel adapters, and mounting hardware in carbon fiber nylon or glass-filled nylon for maximum strength.
Enclosures and Housings
Custom enclosures for electronics, sensors, and control systems. We design for heat dissipation, cable management, mounting features, and environmental sealing. Materials include PETG for chemical resistance, ASA for UV exposure, and ABS for paintability.
Seals, Gaskets, and Flexible Components
TPU and flexible nylon parts for seals, gaskets, vibration dampeners, and protective covers. We print Shore hardness values from 85A to 95A, matching commercial rubber specifications without the mold tooling cost.
Jigs, Fixtures, and Production Aids
Why Choose 3D Printing for Custom Plastic Parts?
- No Tooling: No injection molds, no CNC fixturing, no setup costs.
- No Minimums: One part or one hundred. The cost per part drops with quantity but there’s no minimum threshold.
- Fast Turnaround: Most parts are ready in 24–48 hours, not 4–6 weeks.
- Complex Geometry: Internal channels, lattice structures, and organic shapes that are impossible with machining or molding.
- Design Changes: Update the file and the next batch reflects the change instantly.
- Local Production: Made in Houston, delivered to your door or ready for pickup.
Materials for Custom Plastic Parts
Every application demands a specific material. We match the material to your functional requirements:
| Material | Properties | Applications |
|---|---|---|
| Carbon Fiber Nylon | High stiffness, lightweight, heat resistant | Structural brackets, aerospace mounts |
| Glass-Filled Nylon | Impact resistant, abrasion resistant | Gears, pulleys, wear pads |
| PETG | Strong, chemical resistant, dimensionally stable | Enclosures, fluid handling |
| ABS | Tough, heat resistant, machinable | Automotive, paintable parts |
| ASA | UV stable, weather resistant | Outdoor, marine components |
| TPU | Flexible, rubber-like, durable | Seals, gaskets, grips |
| Resin | High detail, smooth finish | Presentation models, master patterns |
