5. 3D Scanning and Printing

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)

Code Example

  // the setup function runs once when you press reset or power the board
  void setup() {
    // initialize digital pin LED_BUILTIN as an output.
    pinMode(LED_BUILTIN, OUTPUT);
  }

  // the loop function runs over and over again forever
  void loop() {
    digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(1000);                       // wait for a second
    digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
    delay(1000);                       // wait for a second
  }
