Small Batch Manufacturing Without the Tooling Cost

Spline Arc is a Houston based 3D printing farm. We produce functional parts in runs of 10 to 500 units: no molds, no minimum orders, no overseas delays.

  • Bridge production: Print parts while steel tooling is being cut
  • Low volume runs: 50 units for testing, 200 for market launch
  • Same day turnaround: Rush jobs available for urgent needs
  • Engineering grade materials: PETG, ASA, PC, Nylon, TPU

One Print Farm. One Turnaround.

Production runs sized to your launch, not our machines.

Our farm runs 24/7. Whether you need 10 brackets or 500 housings, we scale the job across our printer fleet and deliver on time.

NDA Availability

Mutual NDAs available before any files change hands. Most engagements start with an NDA and a 15 minute scoping call. We do not publish, share, or repurpose client geometry, drawings, or photographs. Your IP stays yours.

Materials We Print

PETG

PETG combines the ease of printing of PLA with the durability of ABS. It offers excellent layer adhesion, chemical resistance, and impact strength. Ideal for jigs, fixtures, enclosures, and parts that need to withstand repeated handling.

ASA

ASA provides superior UV resistance and weatherability compared to ABS. It maintains color stability and mechanical properties under prolonged sun exposure. The material of choice for outdoor applications, agricultural equipment, and automotive exterior components.

PC (Polycarbonate)

PC offers exceptional impact resistance and heat deflection up to 145C. It is the strongest standard FDM material available. Used for functional parts that must endure high loads, temperatures, or safety critical applications.

Nylon (PA)

Nylon delivers outstanding wear resistance, low friction, and high fatigue resistance. It absorbs moisture which increases flexibility and impact resistance. Perfect for gears, bearings, living hinges, and parts subject to repetitive motion.

TPU (Thermoplastic Polyurethane)

TPU is a flexible, rubber like material with excellent abrasion resistance and elasticity. Shore hardness ranges from 85A to 95A. Used for seals, gaskets, flexible mounts, impact absorbing components, and ergonomic grips.

Why FDM for Small Batch Production

No Tooling Costs

Injection molding requires steel or aluminum tooling that costs $10,000 to $100,000 and takes 8 to 16 weeks to machine. FDM 3D printing requires zero tooling. Your first part costs the same as your hundredth. This makes FDM ideal for bridge production, market testing, and low volume runs where tooling economics do not work.

Design Freedom

FDM printing builds parts layer by layer, enabling complex geometries that would be impossible or extremely expensive to machine or mold. Internal lattice structures, conformal cooling channels, and organic shapes are all possible without additional cost.

Rapid Iteration

Design changes require only a file update, not a tooling modification. You can print a design revision today and have parts in hand tomorrow. This accelerates product development cycles from weeks to days.

Domestic Manufacturing

All production happens at our Houston facility. No overseas shipping delays. No customs holds. No minimum order quantities imposed by offshore suppliers. Your parts ship from Texas to anywhere in the US within 1 to 3 business days.
