Spline Arc is a Houston-based 3D printing and CAD design company built for speed, precision, and reliability. We operate a local print floor with professional FDM printers capable of producing functional prototypes, custom parts, and production tooling with quick turnaround. Every part is printed through our Texas workflow, which supports direct quality control, faster iteration, and communication with the team actually building your components.
Working with a local Houston 3D printing shop helps reduce communication gaps, unclear handoffs, and long review cycles. Our clients include product development firms in the Energy Corridor, medical device startups near the Texas Medical Center, university teams, and manufacturing operations across Dallas, Austin, and San Antonio. We offer local pickup when available, statewide shipping, and the ability to iterate on a design through direct discussion with the team preparing the print.
Not every project starts with a CAD file. We model parts from sketches, photos, broken samples, or written descriptions. Our prototype sprint process can include concept review, CAD modeling, one functional printed prototype, revision support, and a complete file pack with production guidance based on the approved project scope. Per-project quotes are provided before work begins so expectations stay clear.
We print in PLA, ABS, PETG, TPU, Nylon, PC, and ASA with layer heights from 0.1mm to 0.3mm and project-specific tolerance review. Maximum build volume is up to 1000mm, accommodating large-format tooling and multi-part assemblies. Material selection is based on your part's functional requirements, and we recommend the right filament for strength, flexibility, heat resistance, chemical exposure, or outdoor durability.
Spline Arc supports inventors, manufacturers, makers, and product teams that need a practical path from idea to physical part. We review wall thickness, orientation, support requirements, fastener locations, assembly clearances, and material behavior before production. That review helps reduce avoidable rework and gives customers a clear understanding of what is possible with FDM printing before committing to a larger run.
Common projects include functional prototypes, custom brackets, equipment covers, replacement parts, shop floor fixtures, large-format models, product samples, and low-volume components. Whether the starting point is a clean STEP file, a rough sketch, a damaged sample, or a short written description, our Houston workflow is built to turn practical requirements into a printable plan.
