Capabilities

From concept file to finished part

Four capabilities, one shop. Everything happens under our roof in Cambridge — no outsourced steps, no lost-in-translation handoffs between vendors.

Rapid Prototyping

Validate form, fit, and function in days, not weeks. We print functional prototypes directly from your CAD files so you can test iterations before committing to tooling or production.

  • · Fast turnaround
  • · Design iteration
  • · Functional testing

Production-Grade FDM

Bridge production and low-to-mid volume manufacturing with industrial FDM. Engineering-grade thermoplastics and repeatable tolerances for parts that need to perform.

  • · Batch runs
  • · Engineering thermoplastics
  • · Repeatable tolerances

CAD Design & Engineering

Sketch, scan, or rough concept — our engineers take it to print-ready geometry, including design-for-additive-manufacturing reviews that catch problems before the build plate does.

  • · DFM review
  • · Reverse engineering
  • · File repair
Why Grand River Manufacturing

The difference is who's on the other end of the file

Compare us to an overseas quoting platform or a print-on-demand marketplace, and it comes down to six things.

Local Ontario Production

Every part is printed, finished, and shipped from our floor in Cambridge — not routed through a broker.

No Overseas Lead Times

Turnaround measured in days, not weeks spent waiting on a boat or customs.

Engineering Review Included

Every job gets a DFM check from an actual person, not an automated quoting bot.

Low-Volume Production Runs

Built for the 10-to-500-part order — too small for offshore tooling, too big to print by hand.

Fast Turnaround

Firm quotes typically land in your inbox within one business day.

Direct Communication

You talk to the person actually running the printer — not a support ticket queue.

Batch Production

Low-volume production manufacturing

Need 10, 50, or 500 of the same part? Grand River Manufacturing specializes in repeatable FDM production runs using industrial-grade materials and standardized processes — so part #1 matches part #500.

  • Repeatable tolerances across the full run
  • Engineering-grade thermoplastics, including PETG-CF & PPA-CF
  • Standardized QC on every batch
  • Pricing scales with quantity — no per-unit tooling costs

Who We Serve

Industries we serve

Wherever a part needs to go from CAD file to something you can hold, we can help.

Industrial Automation Robotics Agricultural Equipment Automotive Product Development Research & Development Manufacturing Maintenance
Material Library

Choose the polymer that matches the job

Every material behaves differently under load, heat, and time. Here's how we typically match polymer to application — your engineer will confirm the right fit at quoting.

PLA

Fast, clean, dimensionally stable

Our go-to material for early-stage concept models and form-fit checks. PLA prints with crisp detail and minimal warping, so you can have a physical part in hand fast.

Pricing

How pricing works

Every job is different, so we don't publish a flat price list — but here's the general shape of it.

Prototypes

Typically the most affordable option — most are quoted the same business day.

CAD & Engineering

Billed by the scope of work involved, not a flat rate.

Production Runs

Scales with quantity — the more you order, the lower your per-part cost.

Reverse Engineering

Quoted individually based on part complexity.

Every quote is free, with no obligation.

Request a Quote

Turn your file into a firm quote

Tell us what you're building and drop in your file — an engineer will review it and follow up, usually within one business day.

Drag & drop your STL, STEP, or 3MF file

or click to browse — .STL .STEP .STP .3MF .OBJ, up to 200MB. Don't have a file yet? No problem — leave this blank.

Large CAD files don't travel over this form — once you submit, we'll reply with a one-click way to send it over.
