When 3D scanning makes sense (and when it doesn't)

"Can you scan it and print it?" is a common question. Sometimes yes — often a different approach gives a better result.

The possible deliverables - Scan mesh: a dense triangle mesh of the visible surface. Great for capturing organic shapes; hard to edit - Printable mesh: a scan mesh that's been cleaned, closed and made watertight so it can be printed - Reverse-engineered CAD: a model rebuilt from measurements and/or a scan with true planes, holes and dimensions. Editable and reliable for fit - Parametric reconstruction: reverse-engineered CAD with design intent captured as editable features and dimensions - Inspection: comparing a part to a reference to see where it deviates

When scanning helps - Organic or sculpted shapes that are hard to measure - Fitting a new design around an existing complex object - Capturing a shape where approximate accuracy is enough

When measuring and CAD is better - Functional mechanical parts with flat faces, holes and fits - Parts where specific dimensions matter - Small, simple parts where a caliper is faster and more accurate

Things that make scanning harder Shiny, transparent and very dark surfaces, deep pockets, and very small features often need surface preparation or a different method.

What to tell us What the result is for, how accurate it must be, the object's size and material, and whether you can ship it. That's enough to recommend the right approach.
