That plastic part that broke on a machine nobody makes anymore? Replacement parts for discontinued machines are one of the things we print. A thread on what a family-owned FDM shop in Missouri and Florida actually does all day, and what we can do for you.

Send the file and the show date and we will tell you plainly whether it works. Columbia MO and St. Petersburg FL, by appointment, shipping to all 50 states. https://t.co/4ExfoLRcxy

Trade show tip: if your product will not fit in the booth, a scale replica printed from your own CAD will.

[3D Infinity Prints @Positiv3Prints]

What we do not do: the booth itself. Backwalls and lighting belong to your exhibit house. We make the thing people stop to look at.

Why most shops quote you something else: PP barely sticks to anything, including itself, so it lifts and warps off the bed. It takes the right build surface and the right settings. We print it on FDM. If you have a part that should be PP, send it over. https://t.co/1NyJBHQSSb

Polypropylene is the plastic in your dishwasher basket, your car battery case, and every living hinge that still snaps shut after ten thousand cycles. It is also one of the hardest plastics to print on an FDM machine. Short thread on why, and on when it is worth asking for.

[3D Infinity Prints @Positiv3Prints]

Tip: ask for PP when the part meets chemicals or washdown, or has to keep flexing without cracking. If it just sits in the sun, ASA is the better answer. If it has to stay stiff, carbon-fiber nylon. Ask us and we will tell you which one, even if you print it somewhere else.

[3D Infinity Prints @Positiv3Prints]

The honest limit: we print plastics, not metal. If your part has to be metal we will tell you so up front. Both shops are by appointment and we ship to all 50 states. https://t.co/Mw85j8Uv0g

A knob, bracket, guide or housing broke on a machine nobody makes anymore. Here is what actually works for getting a plastic replacement made, from a small FDM shop in Missouri and Florida.

[3D Infinity Prints @Positiv3Prints]

Start with what you have. The broken original is best. A photo with a coin or ruler for scale works, and so does a sketch with a few measurements. We reverse-engineer the part from that and reprint it in an engineering plastic matched to where it lives.

3D printed jigs and fixtures, the short version: they show up in days, a revision costs one more print, and there is no machining or tooling to wait on. A quick thread on getting the right one.

[3D Infinity Prints @Positiv3Prints]

Pick the plastic by the line it lives on. Washdown or chemicals: polypropylene. Sun and heat: ASA. Has to stay stiff under load: carbon-fiber nylon. And when the line changes, you do not rework the fixture, you print the next version.

Tip 3: you do not need a batch. There is no mold or tooling in 3D printing, so one part costs what one part costs. Single-part orders are normal here: a broken bracket, a jig, a test fit before anyone commits to a mold. Send the file and we will quote it the same business day.

Tip 2: you do not need a CAD file. A photo with a coin or ruler for scale, or a sketch with a few measurements, is a fine place to start. We offer 3D scanning and CAD modeling, so ask us about the best way to get your part in front of us.
