What 3ERP does
3ERP (3E Rapid Prototyping) is a Guangdong, China manufacturer built for rapid prototyping and low-volume production. It runs a large in-house floor of 3, 4, and 5 axis machining centers, lathes, EDM, grinding, and CMM equipment, and it adds vacuum casting, die casting, 3D printing, rapid tooling, injection molding, and sheet metal. With many years of prototyping experience and fast turnaround on small lots, 3ERP is a capable one-stop source for early-stage development work that spans several processes.
Where Wexmar is the better fit
Wexmar is a US production machine shop. Rather than a broad prototyping menu, it concentrates on turned, milled, and Swiss parts made domestically, with the maker directly accountable for the result.
Wexmar is a US CNC machine shop in Canastota, NY that ships nationwide. The shop runs 10 CNC lathes, 6 Mazak horizontal machining centers (3 and 4 axis), and 4 Maier MLK-32 Swiss lathes turning bar stock to 32mm diameter, with 2 Brown & Sharpe CMMs for in-house inspection. Work runs from one-off parts through long-run production. Wexmar is SAM registered (CAGE 16AD7), NIST 800-171 scored 110 of 110 in SPRS, DFARS-relevant, Buy American, and Made in USA. Quality is ISO 9001-aligned.
3ERP offers processes Wexmar does not, including 5-axis machining, wire EDM, casting, injection molding, 3D printing, and sheet metal. If a program needs any of those, 3ERP or a similar multi-process shop is appropriate. Wexmar's lane is domestic turned and milled production with in-house CMM inspection and federal compliance already established.

How to decide
For mixed-process prototypes and short overseas runs, 3ERP is a strong option. For turned and milled metal parts that must be made in the United States, held to a CMM, and supported by federal registrations, a domestic direct shop is the cleaner path. Wexmar quotes prototypes and production from the same drawing. See CNC turning or get an instant quote.
Materials, tolerances, and lead time
Wexmar machines common and specialty metals for turned and milled work, including aluminum, stainless, carbon and alloy steels, brass, and bronze, with material choice driven by the drawing. The four Maier MLK-32 Swiss lathes handle small, tight-tolerance turned parts in bar stock to 32mm diameter, while the 6 Mazak horizontal machining centers cover 3 and 4 axis milled work. Every job can be checked on the shop's two Brown & Sharpe CMMs before it ships, and first-article and in-process inspection scale with the run. Lead time tracks material availability and quantity rather than a queue in someone else's plant, and the same drawing that priced the job runs it from prototype through production.
