Using a 3D printer

Using a 3D printer

How does a 3D printer work? How can you create product prototypes, spare parts, artworks, toys and other objects? These and other questions are answered in the course in 3D printing.

3D printing and 3D printers make it possible to create unique shapes and objects in a way that previously was possible only in dedicated prototype workshops with specially trained personnel. 

This two-day course will show how the 3D CAD process and 3D modelling work, and how to print physical 3D objects in a 3D printer. Theory and practical work alternate during the course.

For whom is the course intended?

The course is suitable for both adults and children older than 12 years who want to learn how to create models and physical objects, and to master the basic principles of 3D printing. Maybe you work as product developer, designer, inventor, or similar - or maybe you’re an enthusiast and like to create things.

Previous knowledge required

You should be familiar with using computers and should be reasonably proficient in English, since some of the programs interfaces and terms used are English.

You regularly use different types of computer program, are familiar with frequently used keys on the keyboard, and know how to open and save files in designated locations. You will need a portable PC or Mac with the web browser Google Chrome installed. For slightly more advanced 3D modelling, it’s a good idea to download and install Sketchup Make 2016 on the portable computer you intend to use during the course.

It is an advantage if you have experimented with some basic modelling in a CAD/3D-modelling package before taking the course. This is, however, not an absolute requirement, since we will go through the basics using the online system during the first meeting.

Course contents

• the theory of 3D printing - Its effects on society, industry and individuals - Different types of 3D printer and the technology they use - Purchasing guide - Examples of fields of use and applications
• find free digital models online and download them
• prepare models for printing and test the effects of changing orientation. Examine also the difference between printing with and without support structures
• select and exchange materials and plastic wires in 3D printers
• starting your first print job
• basic modelling for 3D printing - angles, overhangs, support structures
• create simple digital models in Tinkercad for 3D printing
• review the settings available to optimise the result of printing
• online services to order models made in specific materials, such as ceramics or metals.

Course structure

Two meetings with joint discussions, practical work and individual supervision. The course takes place at Tom Tits Experiment in Södertälje. 

Other information

You use your own portable PC or Mac. We use a 3D printer provided by Tom Tits. We will be using free software that can run online in the Chrome web browser or downloaded and installed on your computer. Plastic wire (100 g) is included in the course fee for the printing of a freely chosen 3D object. Further plastic wire can be purchased for SEK 300 per kilogram.


The course is held regularly: send an enquiry about dates if you are interested in taking it.

A lunch break is taken from 12.00-1.00 pm. Lunch is not included in the course fee, but a restaurant and café are available at Tom Tits Experiment.
