Manufacturing Tooling · Jigs · Fixtures
3D-printed jigs and fixtures can locate, hold, guide or inspect components using tooling designed around a specific product, operator and workstation.
Jigs and fixtures are rarely visible to the customer, but they influence how accurately, safely and consistently work is performed. Because these tools are usually specific to one product or operation, they are strong candidates for digital manufacturing.
3D printing can make one-off and low-quantity tooling practical without a dedicated mould. A fixture can include custom locating pockets, cable paths, ergonomic handles, labels and hardware interfaces matched to the actual workstation.
3DRM Tech provides 3D printing in Montreal alongside CAD, scanning and CNC for custom production aids and tooling.
Short answer
A jig guides a tool or operation; a fixture locates or holds a workpiece. FDM and SLS can produce many assembly aids, drill guides, nests, inspection fixtures and machine-specific holders when load, heat, wear and accuracy fit the selected material and process.
01What are jigs and fixtures?
A jig normally guides a tool or repeat operation, such as a drilling guide or alignment template. A fixture normally locates or holds a workpiece during assembly, inspection or manufacturing. In practice, custom production aids can combine both functions.
The best tool creates repeatability around the real operation. It should control the important interfaces without making loading, unloading, cleaning or maintenance unnecessarily difficult.
02Why use 3D printing for production tooling?
Operational advantages
- Geometry matched to the part
- Lightweight operator handling
- Integrated labels and guides
- Rapid replacement or revision
Economic advantages
- No dedicated mould
- Practical one-off quantities
- Digital design changes
- Repeat production from files
Printing is not always cheaper than machining. It is valuable when customization, complexity, low quantity and design change align with additive manufacturing.
03Types of jigs and fixtures that can be printed
04Which printing process fits tooling?
| Process | Why it may fit | Review carefully |
|---|---|---|
| FDM | Practical for larger tools, iterations and many functional fixtures | Orientation, infill, supports, heat and load |
| SLS | Durable nylon and complex geometry without conventional supports | Stiffness, finish, powder access and size |
| SLA | Fine detail and smooth reference surfaces | Resin behaviour under shop-floor load and environment |
05Selecting a fixture material
Material choice depends on mechanical load, clamping force, impact, temperature, chemicals, moisture, UV, abrasion and expected cycles. PLA may suit a visual template while PETG, ABS, ASA, nylon or another engineering material may better fit functional use. Match the specific datasheet and process to the workstation.
06How to design a 3D-printed jig or fixture
Define the operation
Document what the operator, machine or inspection step must accomplish.
Identify datums and interfaces
Mark the features that control part position.
Capture the workpiece
Use CAD, measurements, photos or 3D scanning.
Design for use
Add access, handles, labels, clearances and fasteners.
Prototype at the workstation
Test loading, alignment, ergonomics and cycle behaviour.
Revise and validate
Approve material, process and file revision.
Produce and control spares
Retain controlled files for replacements.
CAD design can create tooling around an existing component, workstation or rough concept.
07Inserts, wear surfaces and maintenance
Repeated threads, clamps, pins and abrasive contact points may benefit from metal inserts or replaceable elements. Designing sacrificial wear pads can make maintenance easier than replacing the complete fixture. Document fasteners and replacement components with the tool revision.
08Ergonomics and shop-floor safety
Consider grip, weight, edges, pinch points, visibility, loading direction and error prevention. Colour, labels and asymmetric features can make orientation obvious. A printed fixture does not replace a proper safety review, guarding or process validation.
09When should tooling be CNC machined?
CNC machining may be preferable when tooling requires metal stiffness, precision interfaces, substantial wear resistance, heat capability or high clamping loads. Hybrid fixtures can use a printed body with machined inserts, pins, bushings, plates and standard hardware.
10Cost and return-on-investment factors
Cost depends on CAD work, size, material, process, quantity, hardware, finishing and inspection. Business value may come from reduced setup time, fewer positioning errors, improved ergonomics, shorter changeovers or faster replacement—not only the price of the fixture.
For repeated sets, low-volume production can retain a validated tooling revision for follow-up batches.
11What should you send for a tooling quote?
Send the workpiece or CAD, workstation photos, required operation, locating features, load, temperature, chemicals, expected cycles, quantity and current pain point. Video of the existing process can also clarify handling and access.
Need a custom jig, fixture or production aid?

// common questions, answered
Can jigs and fixtures really be 3D printed?
Yes. Many assembly aids, guides, inspection tools and holders are suitable when load, heat, wear and accuracy fit the process.
What is the best material for a printed fixture?
There is no single best material. Select according to load, stiffness, temperature, chemicals, wear and service life.
Is FDM strong enough for factory tooling?
It can be suitable when material, geometry and orientation match the use. Demanding tools may require SLS, CNC or a hybrid.
Can you design a fixture if I only have the part?
Yes. CAD can be developed from the component, measurements, photographs, scans or available drawings.
Can metal inserts be added?
Yes. Threaded inserts, bushings, pins and plates can reinforce loaded or frequently serviced interfaces.
Can a fixture be reproduced later?
Yes. A validated and controlled digital file can support replacement or repeat orders.
When should a fixture be machined?
Choose machining when metal, tight interfaces, high stiffness, heat or severe wear drive the requirement.
How can printed tooling reduce cost?
It can reduce custom-tool lead time, setup effort, errors and tooling investment when the application fits additive manufacturing.
Can printed tooling be used for inspection?
Yes, provided locating strategy, stability and required measurement accuracy are validated.
What should I send for a quote?
Send workpiece CAD or photos, the operation, critical interfaces, environment, cycles, quantity and current problem.
