What you'll need

Time needed
Time needed:
In total, for most people it takes between 6 and 20 hours to complete the assembly of a machine.   


Tools needed
Tools needed:
  • Hex keys (1,5 and 2.0mm)
  • Using the included 2.0mm hex-screwdriver saves an awful lot of time compared to an L-shaped hex-wrench!
  • Adjustable wrench or large size pliers
  • Consider also a cordless lithium-ion screwdriver (e.g. Bosch IXO) with a 2.0mm hex bit.   


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

Metric

The design almost completely is metric (using millimeter and meters). Another system for physical dimensions is imperial (e.g. Inches). The nuts and bolts are usually called M3 when they have a 3 millimeter diameter thread.

T-Slots and tabs

T-slots are used throughout the design to connect flat-pack parts at a 90 degree angle.

Important
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 type of wood that the Ultimaker mostly is made of is birch wood, a really dense and sturdy type of wood, great for a machine to lasts very long.

What else?

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!
