Changing a design between production batches
Products change. A bracket gains a hole, a clip needs to be a little stiffer, an enclosure has to fit a new board. Here's how revisions work when your parts are printed in batches.
No mould to change
Because I print each batch from your file, a revision means a new file, not new tooling. That makes FDM a good fit when you expect your part to keep evolving.
What a revision involves
- Send me the updated file (STL, 3MF or STEP), with a note of what changed and why.
- I review it like a new file: printability, orientation, supports and how it fits my size categories.
- If the change could affect fit, function or the size category, I may suggest a new sample before the next batch.
- If the print time, material or size category changes, I send you a new quote.
Changes to the CAD model itself are yours or your designer's to make. Tell me if you need help understanding why a feature won't print well, and I'll explain what I see.
Planning ahead
- Give each revision a clear version name or number, so we both know which file a batch is printed from.
- Tell me about strength, heat, outdoor or food-contact needs before the first sample, not after.
- Test the sample in your real use. FDM parts are usually weaker across their layers, so a change of shape can change how a part performs.

Revising a part?
Send me the updated file with a note of what changed. I'll review it and tell you whether a new sample or quote is needed before your next batch.
