Our Large Format 3D Printing Services

From metal additive manufacturing to large-scale polymer printing, we offer a full range of production-capable 3D printing solutions.

Contract 3D Printing

On-demand additive manufacturing for prototypes and end-use components. Ideal for validating designs, evaluating advanced materials, and running small-to-medium batch production before committing to in-house equipment.

Rapid Prototyping

Accelerated product development using industrial additive manufacturing. Produce functional test components in compressed timelines for design verification, geometric validation, and iterative engineering decisions.

Metal Additive Manufacturing

Large format metal 3D printing for structural, thermal, and high-temperature applications. Produce complex geometries in production-grade metals that traditional fabrication methods cannot easily achieve.

Polymer & Composite Printing

High-resolution large format printing in advanced polymers and composites for tight-tolerance parts. Supports complex geometries, lightweight structures, and end-use components across industrial applications.

Post-Processing & Inspection

Comprehensive post-processing, dimensional inspection, and quality documentation to ensure every printed part meets specification and is production-ready upon delivery.

Additive Manufacturing Training

Full catalog of training courses—from fundamentals to design for metal additive manufacturing—delivered on-site or virtually to help your team maximize ROI from 3D printing technology.

Metals & Plastics Expertise

Industrial-Scale 3D Printing Built for Real Manufacturing Demands

Miller 3D Printing brings over 30 years of manufacturing know-how to large format additive manufacturing. Whether you need structural metal components for aerospace or heavy equipment production in New York and Pennsylvania, or large-scale polymer parts for R&D and medical devices, our engineers review your CAD data and develop application-specific manufacturing plans. We bridge traditional CNC expertise with cutting-edge 3D printing to deliver parts that perform—at scale, on time, and to specification.

About Miller 3D Printing

A team of engineers dedicated to advancing manufacturing through additive technology.

Founded by Al Miller with a clear vision to provide the best in machine tool technology, A.W. Miller has grown over 30 years into a multi-location manufacturing solutions leader headquartered in East Aurora, New York. After becoming the exclusive Mazak distributor for Pennsylvania and New York, the company expanded into Harmony, PA, Ville St. Laurent, Quebec, and most recently Harleysville, PA—serving manufacturers across the entire Northeast corridor. Recognizing that additive manufacturing is the perfect complement to traditional CNC machining, Miller launched the Miller 3D Printing brand to bring large format metal and plastic 3D printing to industrial customers. Today, our engineering teams on both sides work together, giving clients in industries from aerospace to medical devices a single trusted partner for complete manufacturing solutions.
