Singapore 3D-making workshops: check the exported model’s physical size
A model that looks right on screen still needs its intended dimensions communicated through the receiving workflow.

Start with these checks
- The actual accepted file format and units
- Permission to use your own model in the session
- An instructor-supported way to inspect the imported dimensions
The problem
You want to bring your own small model to a Singapore digital-fabrication session, but its preview looks correct while you have not checked whether the exported file will be interpreted at the intended physical size.
Choose a dimension you can explain
Write down one intended overall dimension and the feature it relates to before exporting your model. A screen preview can be zoomed and is not a physical measurement. Bring the dimension as part of your question to the instructor, without claiming the exported file is ready for printing merely because its shape looks recognisable.
Use the receiving workflow’s stated requirements
Singapore provider 3DPS requests millimetre units and lists STL, OBJ, STEP and 3MF in its file-preparation guidance. These are that provider’s requirements, not permission to use any of those formats at every library or workshop. Ask the actual teaching organiser which export and inspection workflow it supports before preparing files for its equipment.

Inspect the imported file before approving the next step
Where the tutor permits it, reopen the exported file through the agreed workflow and compare its reported dimensions with your note. If the size is different, stop and ask how the units or export should be corrected. Do not compensate by repeatedly guessing a scale factor or sending a file to unfamiliar equipment to see what happens.
Keep the making permission separate from the design check
3DPS also asks for the important surface or feature to be identified; a brief dimension note can make your own question clearer. Find current Singapore fabrication sessions through Boardzip’s free event search and confirm whether participants can work on personal models. The provider guideline is a design resource, not a current workshop, machine booking or guarantee that the object will print successfully.

Questions and answers
Does an STL preview prove the model has the right physical size?
The preview’s appearance is not the check. Use the receiving workflow’s reported dimensions and compare them with the intended measurement under the tutor’s guidance.
Can I apply 3DPS’s file requirements to NLB MakeIT?
Do not assume that. They belong to the cited provider. Ask the actual MakeIT or workshop organiser which formats, units and preparation steps apply to its session.
