Modix large format 3D printer for oversized parts and fixtures — large-scale additive manufacturing Long Island NY
Oversized

Large Format 3D Printing

When standard build volumes aren't enough. Our large-format printers produce oversized parts, enclosures, panels, and fixtures as single pieces — eliminating assembly and reducing lead time.

  • Oversized parts printed as single pieces
  • Enclosures, housings, and structural components
  • Trade show models and display pieces
  • Eliminates multi-part assembly
  • Cost-effective for low-volume large parts

Frequently Asked Questions

Answers to the questions we hear most from new customers.

What is the minimum order quantity for injection molding?

We have no strict minimum order quantity. We regularly handle small runs of 100–500 parts and are happy to quote jobs of any size. Whether you need a short prototype run or ongoing production, we'll find an approach that fits your budget.

How long does it take to make an injection mold?

Typical lead times for a new injection mold range from 2–6 weeks depending on complexity, material (aluminum vs steel), and number of cavities. Simple aluminum prototype molds can be ready in as little as 1–2 weeks. We also offer 3D printed bridge molds that can be produced in days.

What plastics do you work with?

We process a wide range of thermoplastics including ABS, polypropylene, polyethylene, nylon, polycarbonate, acetal (Delrin), PETG, TPE/TPU, and engineered resins like PEEK and Ultem. We'll help you select the right material for your application's mechanical, thermal, and chemical requirements.

Can you help with mold design?

Absolutely. We provide full engineering support including Design for Manufacturability (DFM) analysis, mold flow simulation guidance, gate and runner layout, and draft angle recommendations. Whether you have a finished CAD model or just a napkin sketch, we can help refine your design for optimal molding results.

Do you offer rapid prototyping before full production?

Yes. We offer multiple prototyping paths: 3D printing (FDM, SLA, and high-temp resin), 3D printed injection molds for molded prototypes in production materials, and rapid aluminum tooling for bridge production. This lets you validate your design before investing in full production tooling.
