Class Syllabus (March-April)

3D Printer Workshop (MOST Delta)


March 28, April 4, 11, and 18  Saturdays 10-4:45pm



Community Supported Everything

1626 NE Alberta St. Portland, OR


Registration deadline: March 7, 2015


Course Outline: This is a 4 week course to build a 3D printer from the ground up. Through this course you will assemble a 3D printer from parts we have prepared for you. We have spent time ensuring the assembly is easy and fast. You will then upload firmware onto the printer, download and configure software for the printer on your computer, and calibrate the printer. By the end you will be printing things with your printer and have an excellent idea on how to have successful prints.  

What is 3D printing?

    • 3D printing is an additive manufacturing process where a 3-dimensional object is created layer-by-layer from a computer model to a physical object. In this course you will be building a FFF (fused filament fabrication) printer which utilizes biodegradable PLA (poly-lactic acid) thermoplastic as its primary material.

What is RepRap?

  • RepRap stands for Self-Replicating Rapid Prototyper; a project that in 2007 ignited global interest in 3D printing. RepRap initiated a rush of grassroots innovation in additive manufacturing and open source hardware. This course and the printer built is a part of the RepRap project.

What is open-source-appropriate technology (OSAT)?

    • Open-source: Developed in the open and licensed in such a way as to allow their designs to be used, modified and distributed with limited restrictions.  -Wikipedia
    • Appropriate technology: “technology that is designed with special consideration to the environmental, ethical, cultural, social, political, and economic aspects of the community it is intended for” -Wikipedia


Course schedule:

Week 1 – Feb 14 –  Saturday – 1-5pm Printer primer, Assemble motor end and Idler end triangles.
Assemble hotend and effector
Week 2 – Feb 21 –  Saturday – 1-5pm Assemble Extruder/ Install Verticals and circles /Tie-rods, belts and pulleys
Mount electronics and install wiring
Week 3 – Feb 28 –  Saturday – 1-5pm Upload firmware/Calibrate/Configure basic software
Using software
Week 4 – Mar 7 –  Saturday – 1-5pm Calibration continued/ 3D printing Basics/Troubleshooting
Using advanced 3D printing software


Class expectations: Attendance is required to complete your 3D printer on time. You will need a laptop that can play videos, connect to wifi, and has functional USB ports. Make-up classes will not be held. There are on-line resources that will assist you in finishing your printer should you miss a class. You will need to install Repetier Host, Pronterface, and Arduino IDE onto your computer.

Printer Statistics:

  • Print media: PLA only (a heated bed can be added, expanding media options if the power supply is upgraded)
  • Filament diameter: 1.75mm using a wade’s extruder
  • Nozzle diameter: 0.5mm (can be changed for higher resolution)
  • Print volume: ~250mm radius (with 240mm long linking boards) 270mm high
  • Resolution: 100 micron (layer height)
  • Melzi print controller w/ integrated SD card reader
