How do I train a successor to run my 3D printing service’s post-processing?

Post-processing is where a printed part becomes something a customer will accept, and it is often more manual than owners admit. Break it into stages: removing supports, cleaning, sanding or smoothing, curing, dyeing or coating, and final inspection. Each material behaves differently, so keep notes for each and show the successor what the finished part should look and feel like.

Collect samples. A shelf of good parts, marginal parts and failed parts teaches faster than text. Add the settings, times and chemical handling that matter, and write down the safety steps for any solvents, resins or dust. Your lawyer or the relevant authority can say which workplace safety rules apply.

Then shift the work across. Let the successor handle real orders while you check each one against the sample, and slowly reduce your inspection as the results settle. Write short checklists for each product type, with the typical faults and their causes. Ask any staff who do the finishing to help teach, and think about how to keep them, since their hands hold much of the skill. Ask a consultant for help if you want an outside view of the process.

Key takeaways

• Break finishing into stages and record the method for each material separately.
• Keep a shelf of good, marginal and failed parts as a visual reference.
• Write down safety steps for resins, solvents and dust, and confirm them with a professional.
• Reduce your own inspection gradually as the successor’s results stay consistent.
