Hackers – 3D Modelling with SketchUp

roompic

At this week’s session, Kevin introduced everybody to SketchUp, a free 3D modelling program. Models built with SketchUp can be exported to a format suitable for input into Repetier Host, to prepare them for 3D printing.

Incidentally, other options for 3D modelling include Blender (which some may have used previously for modelling) and TinkerCAD (which is web-based so does not require installation).

Here are some notes on getting started with SketchUp – they are taken from an NUI Galway summer camp I was involved in organising a couple of years ago: sketchupnotes

By the way, the picture above is a SketchUp model I built previously of a room.

Important: to export SketchUp models to Repetier, you first need to install the SketchUp STL Extension. Instructions:

  • n the SketchUp main menu, select Window – Extension Warehouse.
  • Search for SketchUp STL (see below), then go through the steps of downloading and installing.
  • Note that you may need to create a Trimble account (Trimble is the company that develops SketchUp).
  • You may see a warning that it is not marked as compatible with your version of SketchUp, but just press OK.
  • After installing the SketchUp STL extension, you will have a new menu item: File – Export STL.
