Our Customer says
3D printing in San Jose, common questions
Straight answers on what Additiv3 prints, where we are, how quoting works and what we can design for you.
Do you offer 3D modeling and 3D design services?
Yes. Alongside printing, Additiv3 offers engineering design: CAD design, 3D modeling and design for additive manufacturing (DFAM). We can take a sketch or an existing part and turn it into a print ready model, tune a design for strength, printability and cost, or make light DFM adjustments to a file you already have. Deeper modeling work is quoted separately once we have seen the project.
Where is Additiv3, and do you handle 3D printing near me?
Additiv3 is a 3D printing shop in San Jose, in the South Bay. Finished parts ship to your address with tracking, and customers in Santa Clara, San Mateo, Alameda, San Francisco, Santa Cruz and Monterey County can choose local pickup at checkout instead. Pickup orders carry no shipping charge, and we contact you to arrange a time once the parts are ready.
What is additive manufacturing, and which processes do you run?
Additive manufacturing is the industrial term for 3D printing: a part is built up layer by layer from a digital model instead of being cut from a block of material. Additiv3 runs two additive processes in house. FDM (fused deposition modeling) prints tough thermoplastic parts such as brackets, enclosures, jigs and fixtures. SLA (stereolithography) cures liquid resin into high detail parts with a smooth surface for cosmetic models, snap fit tests and fine features.
Do you offer rapid prototyping services in San Jose?
Yes. Rapid prototyping is the core of what we do for hardware startups, R&D teams, students and designers across San Jose and the Bay Area. Upload your file, get a price instantly and we print the part in FDM or SLA. Turnaround is same day to three days depending on volume and materials, and small batch production runs use the same workflow.
How do I get a 3D printing quote?
Upload an STL, STEP, OBJ or 3MF file on the quote page, then select the process, material, color, detail, infill and quantity. The price appears instantly from the geometry of your part, so you can compare options before you add anything to the cart. Check out online, or ask us a question from the same page if your part needs a review first.
What materials can you 3D print?
For FDM we print PLA, ABS, ASA, Nylon, PC and more, chosen on the quote page per part. For SLA we print Formlabs resins for high detail work. If you do not see a material that fits your application, ask us and we will help evaluate options for your requirements.
