Engineered for Performance. Built for Production.

We don’t just make parts. We help you figure out how to make better ones. Most manufacturers juggle multiple vendors just to get a part made. Stack3d brings material development, SLS, FDM, and Large Format Additive Manufacturing together under one roof, so your engineering team spends less time coordinating and more time solving the problems that actually matter. From early material development to production-ready parts, we’re built to work alongside you at every stage. No handoffs, no gaps, just a faster path from concept to reality.

Full-Stack Additive Manufacturing

Why Integrated Manufacturing Matters

Most manufacturers source materials from one supplier and printing from another, leaving compatibility and performance to chance. Stack3d brings material development and manufacturing together under one roof, giving you greater control over performance, faster development, and a more efficient path to production.

From material formulation to production-ready parts, our capabilities include:

  • Custom Material Development

  • Engineered Thermoplastics & Specialty Colors

  • Filament & Pellet Manufacturing

  • SLS, FDM & Large Format Additive Manufacturing

  • Rapid Prototyping & Bridge Production

  • Production-Ready End-Use Parts

  • Material & Part Characterization

3D Printing Services Built for Real-World Performance

Idea to Prototype to Production

Stack3d moves projects from concept to functional part with a precision and speed most manufacturers can’t offer, backed by more than 60 years of combined additive manufacturing experience. We combine SLS, FDM, and large format additive manufacturing to match the right process to each application, so you’re never stuck forcing your part into a process that wasn’t built for it. Whether you’re developing a prototype, validating a design, or producing small-batch parts, our team has the depth to get it right the first time.

Additive Manufacturing Capabilities

SLS

Selective Laser Sintering (SLS) is a powder bed fusion process used to create complex geometries and functional prototypes with high dimensional accuracy and consistent mechanical performance.

FDM

Fused Deposition Modeling (FDM) is an extrusion-based process used for durable, cost-efficient parts during early-stage development and rapid design iteration.

LFAM

Large-Format Additive Manufacturing (LFAM) is a pellet-based extrusion process used for large-scale functional components and production-oriented parts where throughput, size, and scalability are critical.

Additional Services & Capabilities

Design & Manufacturability Feedback

Our engineers catch printability and performance issues before they become expensive problems, giving your part the best possible start before production begins.

Material Validation & Testing

We put every material and part through rigorous mechanical and thermal evaluation, so you know exactly how it will perform before it ever reaches the field.

Rapid Prototyping & Bridge Production Tooling

We bridge the gap other manufacturers can’t, with short-run injection molding tools and transitional manufacturing solutions that get you to scale without waiting on full production tooling.

Post-Processing & Assembly Support

From inserts and machining to blasting and assembly prep, we deliver parts that arrive truly ready for end use, not just ready to print.

Custom Material Production

Production of Non-Standard Materials, Including Custom Colors

Few manufacturers can develop their own thermoplastic materials in-house. Stack3d can, including custom color development and non-standard formulations that fall outside typical off-the-shelf material systems. This includes adjusting material properties, integrating recycled content where appropriate, and developing consistent, repeatable color matching for functional and aesthetic requirements. The result is feedstock engineered specifically for your application, built for reliable processing and predictable performance from day one.
