The typical replacement job is small — a hinge, bracket, knob, or clip around 20 cm³ — printed dense (40%+ infill) in ABS or PETG because it has to do the original part's job. The print itself is cheap; most quotes land at the shop minimum of $10–$20. The real value is availability: when the manufacturer discontinued the part, the alternative isn't a cheaper part, it's replacing the entire appliance.

What drives the cost
High infill for strength
Replacement parts fail if printed hollow. 40–60% infill (or more perimeters) raises material and time cost, but on a 20 cm³ part that's still only a couple of dollars.
Modeling can cost more than printing
If no STL exists, someone must measure and model the broken part. CAD time at $20–$60/hr often exceeds the print cost — bring a model if you can.
Material must match the job
Heat near a motor calls for ABS or ASA; outdoor UV calls for ASA or PETG. Material choice changes durability far more than it changes price.

Can a 3D printed part be as strong as the original?
Often strong enough. Printed at high infill in the right material and orientation, most brackets and knobs outlast the appliance. Layer direction is the key weakness to design around.
Why did I get quoted $15 for a tiny clip?
Shop minimums. Setup and handling cost the same for a 5-gram clip as for a large part, so small jobs are billed at the minimum order charge.
What if I don't have a 3D model of the part?
A shop can model it from the broken piece and measurements, billed as CAD labor — commonly $20–$60. Simple geometric parts are quick; complex curved ones aren't.
