The machine still works. The appliance is fine. The car is fine. One small plastic thing broke, and the only answer anybody can give you is that the part is discontinued, superseded, or sold exclusively as part of an assembly that costs more than the repair is worth.

That is one of the jobs we do most, and it is worth saying plainly how it works — including the parts of it we will tell you no about.

You do not need a 3D file

Almost nobody who calls about a broken part has a model of it. That is the normal case, not the hard case.

What we actually need, in order of how much it helps:

The broken part itself. Best possible start, even in pieces. We can measure it directly with calipers, including the features you would never think to mention.
Photos plus measurements. Workable, and often enough. Shoot it on a plain background next to a ruler or a coin, from several angles, and measure anything that has to fit something else — hole spacing, shaft diameter, overall length, thickness.
Photos alone. Enough for us to tell you whether the job is possible, not enough to print from. A photograph has no scale.

From there, building the model is a quoted line item, not an open meter: $45–$150, flat, and you approve the number before anybody starts. If you already have a file that needs resizing, hollowing, or a mesh repair, that is included in the print price instead — see pricing for the whole list.

Why these parts usually want resin

A replacement part is a copy. The job is not "something roughly this shape" — it is the original, because the original is what the surrounding assembly was built around. That makes the small features the whole assignment.

Think about what is actually on a part like that: knurling on a knob so a thumb can turn it. A moulded logo or part number. A thread. A snap-fit tab with a specific radius that lets it click in and stay. A chamfer that lets it seat flush.

Filament printing forms a part by pushing melted plastic through a nozzle, and the nozzle has a width. Features smaller than roughly that width cannot be drawn — they get rounded off, or vanish. Resin has no nozzle. At 25 microns on our Formlabs Form 4, a thread is a thread and the knurling is knurling.

There is a second reason, less obvious: fit. A snap tab that is 0.3 mm too thick does not click, and a shaft hole rounded a few tenths out of round does not grip. Resin holds dimensional detail at the scale small parts actually fail at.

If the part needs to be stiff rather than brittle, we print it in tough resin. Which resin should your part be printed in? covers the options.

When we will tell you to use filament instead

We run both processes and get paid either way, so there is no reason to steer you. Filament is the right call when:

The part takes real load. A bracket that gets stood on, clamped, or torqued. Common filaments bend before they break; many resins are stiffer and more brittle.
The part lives in heat or sun. Anything on a dashboard, under a hood, or outdoors year-round. ABS and ASA are built for that; standard resin is not.
The part is big and plain. If it is mostly volume and no one will ever look closely at the surface, resin is an expensive way to buy plastic.

For the long version of that trade, read SLA vs. FDM: which one does your part need?

What we will not print

This is the honest limit, and it is not a formality. Prints from either process are for display, hobby, and prototyping use — not for load-bearing, medical, food-contact, or safety-critical applications. If the part is a structural bracket in a vehicle's suspension, a component in a child's car seat, or anything that hurts somebody when it fails, the answer is no, and it stays no if you tell us it is fine.

Two other things we cannot do, so you do not waste a call:

Guess at a mechanism we cannot see. If the broken part has internal geometry that mattered and the evidence is gone, we can copy the outside and nothing else.
Reproduce a part that is under active patent or trademark protection for resale. Fixing your own thing is one matter; producing someone else's part for sale is another.

What it costs and how long it takes

Resin jobs start at $29 and filament jobs at $19. Most small replacement parts are near the floor; the price moves with how much material the part drinks, how long it occupies the machine, and how much finishing it needs. Quotes are free and you get a real number the same day, from Josh or Gianluca, not a calculator.

Standard turnaround is 4–9 days, and shipping is free anywhere in the USA. If you are in Cape Coral, Fort Myers, Naples, or the surrounding Southwest Florida area, we deliver it to you at no charge.

One practical note: if the part is bigger than it looks, it still prints — see how big can you actually 3D print? for how oversized parts get split and bonded.

Start the conversation

Call or text (239) 880-2698 and describe the part, or send photos and measurements through the quote form. Files go up to 8 MB there — STL, OBJ, STEP, or 3MF. Bigger than that, send a link or just call.

If it cannot be done, or cannot be done well, you will hear that first and it costs you nothing.
