Engineering Behind Every Layer.
From concept sketch to finished prototype — Duval Prototype & Manufacturing Works delivers precision 3D printed parts and custom prototype design for engineers, inventors, and businesses in Jacksonville and beyond.
Print Technology
We specialize in FDM (Fused Deposition Modeling) — the most versatile and cost-effective 3D printing technology for functional prototypes and custom parts.
FDM builds parts layer by layer from thermoplastic filament — delivering strong, functional, and cost-effective results across a huge range of materials. It's the right choice for the vast majority of prototype and custom part applications.
Custom Prototype Design
Most clients come to us with an idea, a sketch, or a rough concept — not a finished file. We can help develop print-ready 3D models optimized for your chosen process and material.
We don't just print files. We help bring your ideas to life from the ground up.
We translate your idea, sketch, or reference into a precise 3D model ready for printing — no engineering experience required on your end.
Every model is reviewed and optimized for the target process — wall thickness, overhangs, tolerances, and support placement are all dialed in before a single layer prints.
Prototyping is rarely one-and-done. We work in fast revision cycles so your design gets refined quickly based on real printed feedback.
Receive production-ready STEP, STL, and native formats for future use, modifications, or manufacturing scale-up.
What We Print In
Easy to print, rigid, great for concept models and visual prototypes. Available in dozens of colors.
Tough, slightly flexible, and chemical-resistant. Ideal for functional parts that need to hold up in real conditions.
Impact-resistant with excellent heat tolerance. ASA adds UV stability for outdoor-use prototypes.
Flexible filament for grips, seals, gaskets, and wearables. Highly customizable shore durometer.
Strong, slightly flexible, and fatigue-resistant. Great for complex assemblies and demanding end-use parts.
Exceptional strength and heat resistance for demanding prototype applications and structural testing.
How It Works
Share your concept, sketch, reference photo, or CAD file. There's no wrong starting point — we work from wherever you are.
We model or prepare your file for printing, check for printability issues, and get your sign-off before committing to material.
Clear pricing with no surprises. We quote material, process, post-processing, and turnaround time — all upfront.
Parts are printed in-house, inspected, and post-processed as needed — support removal, sanding, priming, or painting per your spec.
Local Jacksonville pickup available. We ship nationwide and stay available for revision rounds and next-iteration work.
About Duval Prototype
Duval Prototype & Manufacturing Works is a Jacksonville-based 3D printing and prototype design shop. We work with engineers, entrepreneurs, small businesses, and first-time inventors who need a real partner — not a web portal.
When you contact us, you talk to the people doing the work. We ask the right questions, push back on designs when it'll save you time, and care about the outcome because our name is on every part that ships.
Get In Touch
Send us your files, sketches, or just a description. We'll review your project and get back to you with a quote — usually within 24 business hours.
