Quick Check in on Reading Reflections for Codeable Objects Reading

• • Reading reflection slides

Reviewing Assignment 1

• • Calling on 3 people to share the results of their first assignment (Alex, Ziyu, Tina)

  • Check in about Instructables links- Emphasis on documenting your efforts towards the objective over completing it.

  • Tips on Documentation: Start your documentation/ notes when you start the project

  • Tips on Booleans: Try to perform them manually

  • Grafting and Flattening output

  • Article on Boolean success/failure: Link

  • Extension of Assignment 1- converting 2.5 D patterns to 3D

--Break--

3D printer Overview

• • Prepping your 3D printer for printing (the basics)

    1. Components of the printer and overview (Ender 3 Pro review)

    2. Bed leveling and zeroing. Optional: You can also review the advanced calibration steps and mods (many of which are printable on the printer)

    3. Filament loading and unloading

  • Slicing Basics

    1. File formats workflow- Grasshopper-> Bake -> Rhino -> .STL -> GCode

    2. Settings for the Ender 3

       • Printing speed - the speed at which the printer head travels and extrudes materials

       • Layer height - height of individual layers of your print

       • Print temperature - temperature the nozzle heats up to.

       • Printing bed temperature - temperature the bed heats up to.

       • Retraction - The rate and behavior at which a printer retracts filament when moving over non-printed areas

       • Infill - density (and structure) of the material between the walls of the print

       • Fan speed- speed of the fan that cools the print

       • Speed of the first layer - reduced speed for the first layer to encourage adhesion to the build plate

    3. Support Structures and Printing tests

       • Limitations of support structures: Increased printing time, deformed printing surfaces

       • Test prints: Calibration shapes will help you to diagnose issues with your printer!

  • Pickup

    1. 3D printers will be available for pickup Today and Thursday After class from 1-2 at Elings Hall 2024

    2. If you do not have transportation to bring your printer home with you, contact me and Mert directly over Slack

-- IF TIME --

• Lesson: Transformation in Rhino and Grasshopper Pt 1: Link

• Transformation Matrix reference in Rhino API: Link

• Extra: Importing external Python Libraries into Grasshopper: Link

After Class

• Comment on at least two student assignments on Instructables

• Indicate your preference for accessing/picking up your 3D printer on this form

• Complete the reading.

• Post a slide with your reading reflections to the shared google slide deck by 6 PM Wed April 6th.

• If you have received your printer, print a calibration object: e.g. a cube, pyramid, or another object

Reading Prompt:

The reading presents different lenses for understanding the application of the robot arm in the Wendell Castle furniture studio: tool, assistant, and collaborator. Which of these applications resonates most with you with respect to your own use of computational design and digital fabrication? Why?

Note: Reading prompts are optional. Feel free to discuss elements of the reading that resonate with you.
