Precision Manufacturing for Complex Engineering Work
Additive and subtractive manufacturing under one roof — from first prototype to production run
Impac Additive 3D combines industrial 3D printing and precision CNC machining in a single facility. No vendor handoffs. No re-fixturing. No guesswork. Engineers and product teams move from complex CAD to validated parts faster, with consistent process control, in-house inspection, and one accountable partner from build to finished component.
Additive Manufacturing Machine Fleet
We operate seven additive technologies under one roof — each chosen for a specific engineering role. Whether you need a functional prototype by tomorrow or 10,000 end-use parts by next month, the right process starts with the right machine.
Industrial scale capacity across seven core technologies.
One integrated workflow spanning polymers, metals, and ceramics:
Polymer and Plastic 3D Printing Services
Production grade polymer parts using HP Multi Jet Fusion and industrial FFF systems. LEARN MORE

Subtractive Finishing & Machining
Tight tolerances. Critical features. Finished in-house — on the same parts we print.
Most shops split printing and machining across two vendors. That adds lead time, cost, and the risk of damage in transit. We keep both processes under one quality system. Print complex DMLS geometry, then machine sealing faces and mating features to ±0.002 in. Build large FDM fixtures, then finish hole patterns to spec. Remove supports, cut threads, hit critical tolerances — without ever moving the part.
Critical features verified with in house inspection. Certificates of Compliance available upon request.
Typical turnaround, same day to next day for finishing operations.

Design With Real Manufacturing Data
Skip guesswork. Review layer height, XY and Z accuracy, minimum feature size, and material properties for every process we offer. Build parts that meet spec the first time.
Engineering-Driven Approach
We don't just print parts — we help you build them better.
Design for Additive Manufacturing
Our engineers analyze your CAD files and recommend design optimizations to reduce cost, improve strength, and ensure printability. We catch issues before they become failed builds.
Tolerance
Optimization
We work with your tolerance requirements to select the right process, orientation, and post-processing steps. Every technology has different capabilities — we match them to your needs.
