The cost of waiting for a part
Many machines in Jordanian factories are imported, and so are their spare parts. When a small plastic guide, knob, cover or gear breaks, the replacement may take weeks to arrive, or the machine may no longer be supported at all. Meanwhile the line is stopped or running at reduced capacity.
3D printing lets a maintenance team produce many non-critical plastic parts in-house, often within a day. It will not replace every spare part, but it removes a lot of avoidable downtime.
Good candidates for printing
- Guides, rails and chutes on packaging and bottling lines
- Knobs, handles, covers and housings
- Low-load gears, pulleys and spacers
- Cable clips, brackets and sensor mounts
- Obsolete parts for older machines that are no longer supplied
Parts to leave to the manufacturer
Safety-critical parts, pressure-bearing components, parts exposed to high temperatures, and parts covered by certification or food-contact requirements should come from the original manufacturer or a qualified supplier. When in doubt, use the printed part as a temporary solution while the certified replacement is on its way.
From broken part to printed replacement
- Measure: use calipers to capture the key dimensions; photograph the part from several angles.
- Model: recreate the part in CAD, or use a 3D scanner for complex shapes.
- Choose a material: PETG for general use, ASA or ABS for heat, nylon for wear, carbon-fiber blends for stiffness, TPU for flexible parts.
- Print and test: fit the part, check clearances and adjust the model if needed.
- Archive: save the final file with notes on material and settings, building a digital spare-parts library.
Build a digital inventory
Once a part is modeled, you never need to stock it physically. A digital inventory of proven files means the next replacement is a print job, not a purchase order. Label printed parts with a version number so the maintenance team knows which revision is installed.
Equipment for a maintenance workshop
An enclosed FDM printer with a hardened nozzle, a filament dryer for nylon and a stock of PETG, ASA and nylon filament cover most maintenance needs. Jordan Automation supplies all of these, plus printer spare parts, from Amman. Contact us to plan a setup for your maintenance team.
Frequently asked questions
Is it legal to print replacement parts for my machines?
Printing parts for your own maintenance is common practice, but check warranty terms and any intellectual property restrictions from the machine manufacturer.
How accurate are 3D printed spare parts?
A well-calibrated FDM printer is accurate enough for most mechanical fits. Expect to print a test part and adjust clearances for tight fits.
Can printed parts be used on food production lines?
Only with materials and processes suitable for food contact. Standard filaments and layer lines can trap residue, so treat food-contact parts carefully and follow your food safety requirements.
