Overview

The transcript summarizes a lecture on 3D printing and scanning technologies. Key topics covered include printer types like FDM, SLA, and binder jetting; design considerations for 3D printing; process differences between additive and subtractive manufacturing; scanning methods using lasers, photogrammetry, and other techniques; file formats like STL; and print farms for higher productivity.

Assignment

group assignment:

test the design rules for your 3D printer(s)

individual assignment:

design and 3D print an object (small, few cm3, limited by printer time) that could not be made subtractively

3D scan an object (and optionally print it)

3DSCAN

Equipment specifications

Item:Near-field 3D Scanner for Design

Manufacturer:Creaform

Model number:Go!SCAN50

I used a handheld scanner to 3D scan my right hand.

3DEdit(FIX)

This document outlines the process for restoring data, including noise removal and hole filling, after 3D scanning with VXelement.

3DEdit(Sculpt)

The 3D data surfaces underwent slight modifications, including wrinkle enhancement, surface smoothing, and partial reconstruction, using Zbrush. The repair work focused on the area around the fingernails, where data was missing.
