The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

This beginner’s class on 3D modeling and 3D printing is series of six tutorials that will help you turn your idea into reality. You’ll start with a hand drawing, extrude into a 3D model, and modify and prepare your 3D model to 3D printing Software.


When you are a beginner and the amount of choices are a bit overwhelming, we recommend to start with Tinkercad. Tinkercad has a free version and it works in browsers that support WebGL, for instance Google Chrome. They offer beginner lessons and has a built in option to get your object printed via various 3D printing services.

Professional 3D Graphic Designer for Education at bottlecapdev, all the tools used are free and easily accessible. The course will teach you the basics of 3D modeling and printing, converting images to 3D models, and critical basic concepts in computer aided design (CAD), including extrusion, scaling, mesh, water tight, and even interlocking parts.

Course Requirements

  • Adobe Photoshop CC, Adobe Illustrator, or other image editing software such as Gimp.
  • Pen or pencil and paper
  • Free 3D modeling software Tinkercad
  • Computer with an updated browser such as the latest version of Chrome (best for 3D and webGL)
  • Digital camera (phone camera is fine)

What You’ll Created

  • Customize your object (think monograms, colors) and finish the class, ready to print
  • You’ll draw your own design that can be turned into a 3D design – you can design anything, from prototype to final product

3D modeling software
3D modeling software also comes in many forms. There’s industrial grade software that costs thousands a year per license, but also free open source software, like Blender, for instance. You can find some beginner video tutorials on our Blender tutorials page. When you have a 3D model, the next step is to prepare it in order to make it 3D printable. It all starts with making a virtual design of the object you want to create. This virtual design is for instance a CAD (Computer Aided Design) file. This CAD file is created using a 3D modeling application or with a 3D scanner (to copy an existing object). A 3D scanner can make a 3D digital copy of an object.

What You’ll Learn

The course will uncover the core processes behind 3D printing and reveal one of the most powerful capabilities of the 3D printing revolution that it’s accessible to anyone, and that companies like Shapeways make the process easier than ever through online 3D printing. The course will cover:

  • Part 1: Intro to 3D Modeling and 3D Printing
  • Part 2: Digitizing your Design in Photoshop CC
  • Part 3: Preparing and Exporting a 3D Model from Photoshop
  • Part 4: Design Tips for Tinkercad
  • Part 5: Designing your 3D Model in Tinkercad
  • Part 6: Uploading Your Design to Shapeways

3D scanners
3D scanners use different technologies to generate a 3D model. Examples are: time-of-flight, structured / modulated light, volumetric scanning and many more.

Recently, companies like Microsoft and Google enabled their hardware to perform 3D scanning, for example Microsoft’s Kinect. In the near future digitising real objects into 3D models will become as easy as taking a picture. Future versions of smartphones will probably have integrated 3D scanners.
Currently, prices of 3D scanners range from expensive professional industrial devices to $30 DIY scanners anyone can make at home.
