Obsolete machine parts, remade

The situation this page is about

A machine that works perfectly well stops because one plastic component has failed. The component is not sold. The manufacturer has moved on, or folded, or wants a minimum order of five hundred, or has quoted a lead time that outlasts the job the machine was bought for.

The alternatives on the table are usually bad: leave the machine down, improvise something that will fail again in a fortnight, or replace an entire working machine because of one part. Remaking the part is the option that keeps the asset.

This page is specifically about equipment — production machinery, workshop tools, plant, laboratory and commercial equipment. If the part is a household or consumer item, our replacement parts page covers that ground and is the better starting point.

Why downtime changes the calculation

The cost of an obsolete part is almost never the cost of the part. It is the cost of the machine not running, and that number is usually much larger and much less patient.

This is why speed matters more here than on almost any other job. Same-day quoting, a prototype on the printer quickly, and a finished part in days is the point of the service. Where a part is needed faster than standard turnaround, say so at the enquiry rather than after — priority scheduling can often be arranged.

It is also worth remaking a part before it fails. If a component has already failed once and you know it will again, having the model already made turns the next failure from a shutdown into a phone call. The measuring is the slow part, and it only has to happen once.

How the job runs

The process is the same as any reverse engineering job: measure the original by hand, model it from those measurements, print a prototype, fit it to the machine, adjust, then print the final part. Where the original is broken, send all the pieces — a clean break often makes internal features easier to measure.

Two things speed this up considerably. First, photograph any moulded part number, logo or casting mark before sending. It occasionally identifies the original manufacturer or an equivalent part still on sale, which is cheaper and faster than anything we can print. Second, say what the part does — what it holds, what it slides against, what it is exposed to. That decides the material and the print orientation, and it is the single most useful sentence in an enquiry.

Matching the part to the duty

Choosing correctly is most of the job, and it happens at the quote rather than after the part arrives.

PETG handles the majority of machine components — covers, guards, brackets, guides, housings — because it takes knocks and daylight better than PLA. PLA is the choice where a part has to be dimensionally crisp and lightly loaded, such as a locating guide or a gauge. Flexible TPU covers anything that has to compress, damp or grip: gaskets, bump stops, pads and seals.

Everyday and moderate loads are ordinary work here — brackets, covers, guides, housings, light drive components. Wear parts are welcome too, and often make excellent sense: a component that costs little and can be reprinted from a kept model on a day's notice beats one that lasted longer and can no longer be bought at all.

Every enquiry gets an assessment of the duty the part has to take — the load on it, the heat around it, what it touches. Where a component would be better in metal or made another way, you hear it at the quote, with a recommendation, so the decision is made before money is spent rather than after.

Who this suits

Businesses with equipment they intend to keep. Maintenance and facilities teams, workshops, small manufacturers, anyone whose machine is worth more than the part that stopped it. Repeat work is common and welcome — once a machine's awkward parts have been measured, the models exist.

Minimum order is $75. It is published so you can judge the fit before you spend time on an enquiry.

Frequently asked questions

How fast can you turn a part around?

Standard turnaround depends on the job, and quoting is usually same-day. Where a machine is down, say so in the enquiry — priority scheduling, including next-day and same-day collection in Geelong, can often be arranged. The modelling is normally the longer half, so a simple part moves considerably faster than a complex one.

The part is completely destroyed. Is it still possible?

Often, yes — send everything, including fragments, or point us at a matching part elsewhere on the machine. A clean break frequently exposes internal geometry that is otherwise hidden. We will tell you how confident the result will be before any work starts.

Can you print a part that is currently under load in a machine?

Covers, brackets, guides, spacers and housings under everyday and moderate load are routine work, and wear parts often make good sense as consumables. Send the details of the load and what sits around it, and you will get a clear assessment at the quote — including a recommendation on the right process where a component belongs in metal.

Can you hold a spare in reserve for us?

The model is kept once it exists, so a reorder is a print rather than a fresh job. Many customers have one printed to sit on the shelf, which is usually the cheapest insurance available against the same failure happening again.

Will it last as long as the original?

It will give you a good serviceable life, and — unlike the original — it can be reprinted from a kept model on a day's notice for very little. For a part you can no longer buy at all, that is a considerably stronger position than the one you are in now. Every quote includes an assessment of the duty so you know what to expect.
