It is not 100 USD. The BOM does not include the build table, which is especially important for this printer for two reasons - one, that is how you add layers, the table moves down. Two - the table has to move even during the layer because the print head moves up and down as it changes position.

So it is misleading to use the $100 in the title of the article.

from the zdnet article:

"The primary advantage is to reduce the overall bill of materials — and Harley is aiming for under $100 by the time the design is fully refined" ...

as I said before, the printer is not built by me ... I was not able to build a robust printer for less than 300 euros.

A cheap Z axis could be built based on the cable drive Z from Tantillus, perhaps substituting a DC motor with optical encoder and gearing. Z doesn't have to be fast, and the gearing combined with servo control could keep the platform still. Alternatively this might finally be an application for those cheap printer pulls people keep trying to find a use for.
