3D models

The best way to view the pumps and see how they are assembled is by using Lego Digital Designer. This is a 3D application designed by Lego to help people design their own models before building them. We have created several different models for you to view in our Files sections.

There are several alternatives to Lego Digital Designer as well, each with different strengths and weaknesses:

Single pumps versus arrays

The pumps can either be built as stand-alone pumps or they can be multiplexed as an array.

Why arrays of four?

We tend to make arrays of four because:

  1. If longer, these tend to be unwieldy and not rigid enough
  2. Our controllers can control sets of four by default (see the electronics section for more information).

Rubber bands

Rubber bands are an integral part of the pumps. We use them to help keep syringes in place when they are loaded on the pumps. It's important to buy a bag of rubber bands ahead of time.
