How to Create a 3D Model from Scanned Data in 5 Easy Steps Richard Hagen NASA/JSC/ES2 [email protected] In-Space Inspection Workshop 2017 1/31/2017 R. Hagen, NASA/JSC/ES2 1 Abstract Additive manufacturing is a cost effective way to generate copies of damaged parts for demonstrations. Integrating scanned data of a damaged area into an existing model may be challenging. However, using the relatively inexpensive Nettfab software (from one can generate a “watertight” model that is easy to print. 1/31/2017 R. Hagen, NASA/JSC/ES2 2 Step 1: Scan Data of Damage • Example of Scanned Data saved in a STL (Standard Tessellation Language) Format 1/31/2017 R. Hagen, NASA/JSC/ES2 3 Step 2: Import Data into Nettfab and Make Repairs Imported data is cleaned up and holes filled in so that the damaged area is now one solid model or “watertight”. 1/31/2017 R. Hagen, NASA/JSC/ES2 4 Step 3: Combine the “Repaired” Scan with the Desired Model Nettfab’s Boolean function subtracts the scanned damage from the target part Scanned Data Model 1/31/2017 R. Hagen, NASA/JSC/ES2 5 Step 4: Generate a New STL File Export a new stl model file of the damaged part Nettfab also allows one to add text 1/31/2017 R.
