Exploring the Right 3D Printing Process for Your Project at Mack Prototype
At Mack Prototype, we know that not all 3D printers—or printed parts—are created equal. That’s why we offer five distinct 3D printing technologies, each with its own unique strengths, material options, and applications. Whether you need a fast prototype, functional parts, or small-batch production, we’ve got the right process for your project.
Carbon Digital Light Synthesis (DLS)
Ideal for small (5-inch or less) parts that closely mimic injection-molded materials, Carbon DLS delivers high-quality, ridge-free surfaces using advanced light projection. With fast print times (under 4 hours) and versatile material options—including clear, elastomeric, and UL94V0-rated resins—DLS is perfect for strong, flexible prototypes and functional parts.
Fused Deposition Modeling (FDM)
FDM is the most widely used 3D printing process, and we’ve taken it to the next level. With one of the largest FDM printers in New England (39″ x 24″ x 24″), we print everything from small components to full-sized parts in a variety of materials—including ESD-safe and UL94V0-rated options, as well as actual thermoplastic materials like ABS, PC, Nylon and even PEI (Ultem). Our high-performance equipment allows us to deliver accurate, durable parts in just 1–2 days.
Stereolithography (SLA)
The original 3D printing technology, SLA is perfect for high-resolution, highly detailed parts. It’s a go-to for fit and finish models, marketing prototypes, and master patterns. SLA parts require post-curing and light sanding, but they print fast and beautifully—ready in 1–2 days using clear, elastomeric, tough, or high-heat materials.
HP Multi Jet Fusion (MJF)
Need high-speed production? MJF prints isotropically and finishes builds in under 14 hours. Best suited for low-volume production runs (up to 10,000 units) and parts under 10 inches, MJF uses durable materials like nylon, polypropylene, and TPU, with the ability to dye, paint, or finish parts as needed.
Selective Laser Sintering (SLS)
The workhorse for production. SLS offers higher tolerances than MJF, making it ideal for medical, aerospace, and industrial applications. While it has a longer build time (3–5 days), it creates larger, tougher parts with exceptional precision. Like MJF, parts can be dyed and finished to your specs.
Not Sure Which 3D Printing Process Is Right for You? We’ve Got You Covered.
Choosing the right 3D printing method can be tough, but that’s where our expertise comes in. Our team will guide you through the options, ensuring your parts are produced with the ideal balance of speed, performance, and cost.
And 3D printing is just the beginning.
Mack Prototype also offers urethane casting, CNC machining, short-run injection molding, in-house mold design, and tooling services to support your product from concept through pre-production. Contact us today to start your next project with confidence!
