Custom CNC Machining
When printing is not enough, machine the part.
CNC machining becomes the better manufacturing choice when a part requires metal strength, tighter dimensional control, specific machined surfaces, threaded features, durable interfaces, or production materials that are not practical to achieve with 3D printing alone.
3DRM Tech supports custom CNC machining in Montreal for engineering teams, manufacturers, product developers, robotics companies, automotive projects, industrial equipment, and hardware startups. Our capabilities include CNC milling, CNC turning/lathe work, and sheet-metal fabrication.
Not sure whether your part should be printed or machined? Because 3DRM Tech
offers both processes, we can recommend the manufacturing route around the
part instead of forcing the project onto one technology.
CNC & Metalworking Capabilities
Machining and fabrication for functional, production-ready parts.
From a single prototype to repeat low-volume components, the process is selected around geometry, tolerance, material, finish, and production needs.
02
CNC Turning & Lathe Work
Precision turned components including shafts, spindles, bushings, fittings, threaded parts, spacers, and rotational components in machinable metals and plastics.
03
Sheet-Metal Fabrication
Laser cutting, bending, and welding for sheet-metal components, enclosures, brackets, panels, guards, and fabricated assemblies.
04
Prototype CNC Machining
Machine real production materials during product development when mechanical accuracy, metal properties, threads, bearing interfaces, or machined surfaces need to be tested.
05
Custom Metal Parts
Manufacture one-off and custom components for machinery, robotics, automotive, industrial equipment, product-development projects, and specialized assemblies.
06
Low-Volume CNC Production
Move validated designs into repeat machining runs when you need consistent parts without committing to mass-manufacturing quantities.
CNC Machining Materials
Choose the material around the application.
Material affects strength, stiffness, weight, wear, corrosion behavior, machinability, cost, and final performance. 3DRM Tech currently lists aluminum, steel, brass, titanium, and engineering-grade plastics among its CNC machining materials.
Discuss Material Options →
Aluminum
A practical lightweight metal for brackets, adapters, housings, fixtures, prototypes, robotics and product components.
Steel
Suitable when strength, stiffness, wear resistance, or a more demanding mechanical application calls for steel.
Brass
Available for applications where brass is the specified material for fittings, components, hardware, or specialized parts.
Titanium
Available for demanding applications where high strength-to-weight performance or project requirements justify titanium.
Engineering Plastics
Machined plastic can be the right choice when the application calls for a non-metallic material with CNC-level geometry and finish.
Not Sure?
Send the function, load, environment, quantity, and critical requirements. We can help narrow down the suitable manufacturing route.
Precision & Manufacturability
Design the tolerance around what the part actually needs.
3DRM Tech states machining tolerances to ±0.01 mm on standard parts, with tighter requirements available on request. Final tolerance capability depends on material, geometry, feature size, setup, and project requirements.
If your existing CAD needs changes before machining, our CAD design service can help prepare the geometry for the chosen manufacturing process.
Critical Dimensions
Identify the dimensions and interfaces that actually control fit, alignment, sealing, motion, or assembly.
Threads & Mechanical Interfaces
CNC machining is well suited to components where threads, shafts, bushings, bearing fits, or mechanical interfaces matter.
Machined Surface Requirements
Surface expectations can influence tooling, process planning, material selection, and cost.
DFM Before Production
Unnecessary tolerances, inaccessible geometry, and avoidable setups can increase cost. Review the design before cutting material.
CNC Machining vs 3D Printing
Which process should you use?
Both processes are valuable. The best choice depends on the part rather than which technology sounds more advanced.
| Requirement | CNC Machining | 3D Printing |
|---|---|---|
| Metal parts | Strong choice for solid metal components and production materials | Best suited to the additive materials available for the selected process |
| Tight tolerances | Preferred when mechanical accuracy and critical interfaces drive the project | Useful for many functional parts, but process capability differs by technology |
| Complex internal geometry | Tool access can limit some features | Often stronger for complex internal channels, organic shapes and consolidated geometry |
| Fast design iteration | Useful when the prototype must be tested in the final material or machined form | Often efficient for quick design iterations and early prototypes |
| Machined finish | Natural advantage for machined surfaces and metal interfaces | May require post-processing depending on the desired finish |
| Hybrid development | A common workflow is to 3D print early prototypes, validate the geometry, then machine the final or production version. | |
Need help choosing? 3DRM Tech works with both subtractive and additive manufacturing. Send your CAD file and application requirements, and we can recommend printing, machining, or a combined workflow.

Yes. 3DRM Tech lists 3-axis and multi-axis CNC milling for custom prismatic components and complex machined parts.
Can you fabricate sheet-metal parts?
Yes. Current capabilities include laser cutting, bending, and welding for sheet-metal components and enclosures.
Should my part be CNC machined or 3D printed?
CNC is usually the stronger choice when metal, tighter tolerances, machined surfaces, threads, or production materials are critical. 3D printing can be better for fast iteration and complex additive geometry. Read our CNC vs 3D printing guide.
Can you help if my CAD is not ready for machining?
Yes. Our CAD design service can help create, modify, or prepare geometry before machining.
Can you machine replacement parts when drawings are missing?
Potentially, yes. 3D scanning and CAD design can be used to reverse engineer an existing physical component before it is evaluated for CNC machining.
Where is 3DRM Tech located?
