Why start with jigs and fixtures
Every production line relies on small tools: drilling jigs, assembly fixtures, go/no-go gauges, part holders, cable guides and protective covers. Traditionally they are machined from aluminum or steel, which can take weeks and costs a lot for a part that only holds another part in place.
A 3D printer can produce the same tool overnight in engineering plastic. When a product changes, you update the CAD file and print a new version the same day. For factories in Jordan's industrial estates, this also reduces dependence on external machine shops and imported tooling.
What you can print
- Assembly fixtures that hold parts in the correct position
- Drilling and cutting guides
- Inspection gauges and go/no-go checks
- Soft jaws and nests for vises and CNC machines
- End-of-arm tooling and grippers for robots
- Labels, trays and organizers that fit your exact parts
Choosing the material
PLA is fine for prototypes and light-duty tools at room temperature. For the shop floor, PETG adds toughness and chemical resistance. ABS and ASA handle higher temperatures, and ASA also resists UV. Nylon and carbon-fiber reinforced filaments (such as PA-CF or PET-CF) give the stiffness and wear resistance needed for fixtures that are used thousands of times.
Design tips for strong printed tools
- Orient the part so the main loads run along the layers, not across them.
- Use more walls (perimeters) rather than only higher infill; walls carry most of the load.
- Add threaded inserts or captured nuts instead of printing fine threads.
- Place metal pins or bushings where wear is highest.
- Add fillets to inside corners to avoid stress concentrations.
- Label the fixture with its part number and version directly in the print.
Choosing a printer for the shop floor
An enclosed FDM printer with a heated chamber area handles ABS, ASA and nylon without warping. If you plan to print carbon-fiber filaments, you need a hardened steel nozzle and extruder parts that resist abrasion. A large build volume lets you print bigger fixtures in one piece. Reliability and local spare parts matter more than the fastest speed on paper.

Frequently asked questions
Are 3D printed fixtures strong enough for production?
Yes, for many applications, when the right material and design are used. Carbon-fiber reinforced nylon fixtures are widely used on assembly lines. Add metal inserts where wear or clamping forces are high.
Which filament is best for jigs and fixtures?
PETG is a good general choice. For stiffness, heat and wear resistance, use nylon or carbon-fiber reinforced filaments on a suitable printer.
Do I need an industrial printer?
Not always. Many factories use professional desktop FDM printers with an enclosure and hardened nozzle, which cost far less than industrial systems.
