Welcome to Chapter 1 of the 3D printing workshop. We are going to take a second to investigate the tech behind 3D printing before we jump into printing. By the end of this chapter you should:

  1. Have learned about some of the popular 3D printing technologies.
  2. Have a good understanding of where 3D printing is being used and why.
  3. Know what type of manufacturing process 3D printing is, and more importantly why.
  4. Understand what materials are used by 3D printers
  5. Understand what hardware is on a 3D printer and how it has evolved since the first consumer printers
  6. Understand the workflow and software required to use a 3D printer.

Goal: To investigate FDM printing technology alongside other 3D printer technologies to gain a better understanding of the way we print models.

Different 3D Printing Technologies

Goal: To understand different types of manufacturing processes', namely where 3D printing lies on the spectrum.

Manufacturing Processes

Goal: This section will discuss realistic limitations of 3D printing

Where does FDM 3D Printing fit with with you, the Maker?

Goal: In this section we discuss filament. From the standard sizes right through to some of the newer filaments on the market, this section will give you a decent understanding of printer filaments.


Goal: In this Section we look at the main components and parts in a 3D printer. Futhermore, we discuss how that technology has evolved over the past years to arrive where it is at today.

3D Printer Hardware

Goal: In this section we discuss the basic workflow when using a 3D printer. We discuss CAD & 3D printer software options for makers and decide on what software we will be using in the future.

If you want to follow along in the next chapter, you can download the latest version of Cura.

Workflow of 3D Printing: Taking Files From a 3D Model to Printer Code
Preparing, Slicing and Printing Your First 3D Model
6 Lectures 35:37

Here we are at Chapter 2! Now that we have a decent idea of what 3D printing is, and how it comes together, we are going to learn how to prepare and print our first 3D model!

This chapter will cover the following topics:

  • Installing your printer using Cura
  • The basic settings of Cura
  • Model manipulation on the Cura Print Bed
  • Cura's advanced settings 
  • Preparing your printer for printing (loading filaments, cleaning the bed etc)
  • Removing your print from the bed
  • First Print Results!

Goal: In this section we are going to install a printer to our fresh Cura installation, then we take a look around the basic settings of Cura.

Printer Install and General Overview of a Print Slicer

Goal: In this section, we are going to learn how we can duplicate, rotate, scale and move our model around in Cura.

Model Manipulation

Goal: In this section, we venture beyond quick print settings and take a look at the full palette of print settings in Cura.

Advanced Settings in Cura

Goal: In this Section, we learn how to prepare our printer so that we start our first 3D print the right way.

Printer Preperation

Goal: Congratulations! Your first print has completed successfully, now let's learn how to remove that part from your print bed without damaging ourselves or the printer.

Removing a Print From the Bed & Print Results
3 Lectures 05:04

In this Chapter, we are going to look at the most popular filaments in more detail, namely their properties, the level of printing difficulty and popular uses.

We will be looking at the following features of each filament:

  1. The Temperature required for print
  2. The Bed Temperature required for print adhesion
  3. Solubility of material - what chemicals you can treat this filament with
  4. Impact Resistance of the material - how easily it breaks
  5. Warping/Shrinking issues of filament
  6. If the filament is rigid or flexible
  7. The fumes the filament lets off as it is printed - ventilation considerations
  8. Is it biodegradable
  9. Ease of use - Is it easy, average or hard to manage when printing with.

Goal: We will take a look at the story behind ABS Filament, including its properties & uses with your 3D printer

ABS Overview

Goal: We will take a look at the story behind PLA Filament, including its properties & uses with your 3D printer

PLA Overview
Fix My Print!
4 Lectures 30:43

Goal: We keep hearing about this print issue called warping, in this video, we will investigate the causes and fixes available for warping 3D prints.


Goal: Stringing is a common issue with a simple fix, in this video, we will look at some printer tests that can dial in your printer to remove stringing entirely.


Goal: Overhangs can be the bane of your 3D printing life, in this video we are going to learn how to set up our printer to deal with overhangs.

Overhangs and Supports
Printer Maintenance and Where To Next
3 Lectures 14:04

Goal: The mechanical parts on your 3d printer need some TLC too, in this video we show you the basics.

Mechanical Maintenance

Goal: Printers printing printers? In this video we show you where you can download replacement part STLs as well as how you can slice them to make your replacements as durable as possible.

Printing Replacement Parts

Goal: In this video, we talk about where to go now that you have learned all the printing basics. Additionally, I give you some personal recommendations for resources and communities for 3D printing.

I'm Graham - the founder of Core Electronics. I have been learning, educating and making for over 15 years. Twelve of those were as an Avionics Technician in the Royal Australian Air Force, maintaining fighter jets and in deeper level maintenance workshops. A technically demanding job with broad exposure to many facets of electronics, which led to mentoring and educating others as a senior technician.

During that time (in 2007) I founded "Core Electronics" in Australia which has evolved to become a leading retailer for maker electronics and educational resource for tens of thousands of makers.

In 2016 we launched "Knowledge Factory" in Newcastle (Australia) - a space where we hold free community workshops to walk people over the hurdles with maker tech such as Arduino, 3D Printing and Raspberry Pi. Wonderful!

At every leg of my journey, I've been compelled to learn new skills and help others with their projects. We're now on Udemy and we look forward to helping so many others around the world.
