Mechanics build guide
|Mechanical assembly of the Ultimaker revision 4 (click for an overview)|
This revision 4 of the assembly instructions is online since April 16, 2013 and is meant for Ultimaker kits shipped from the 15th of April 2013. If you have an Ultimaker kit that was shipped before this time, please take a look at the revision 3 assembly instructions. For older revisions go to the bottom of this page.
What you'll need
In total, for most people it takes between 6 and 20 hours to complete the assembly of a machine.
An Ultimaker kit comes with many packs. See the page for your batch to check its contents: for example: batch 6's page.
There should be more nuts and bolts in the packs than you will need, so don't worry if you have a few left!
If you'd like to paint your Ultimaker before assembly, see Painting Your Ultimaker.
Basic design concepts
The design is almost completely metric (using millimeter and meters). Another system for physical dimensions is imperial (inches and feet). The nuts and bolts used are mostly M3 - they have a 3 millimeter diameter thread.
T-Slots and tabsT-slots are used throughout the design to connect flat-pack parts at a 90 degree angle.
|Some pictures may show square nuts in places other than T-Slots; just use hex nuts instead on your build.|
Why use wood?
Wood is an incredibly strong material for its weight. Moreover, everyone can modify a piece of wood by sawing, drilling or filing away material. You can also paint it! We want you to feel free to modify your machine to your liking. And we'd love to hear of your adventures! Another reason to choose wood over e.g. acrylic is that you will not easily crack wood when you over-tighten a bolt, while acrylic would break without giving you a warning. The Ultimaker is made of birch plywood. Birch is a really dense and sturdy type of wood, great for a long-lasting machine.
As designers of the machine, it's hard for us to think of which terms to mention, because we've gotten so used to them. Please tell us what else we need to explain here!
