 1. The [Prusa i3MK3](https://www.prusa3d.com/) is one of the most popular open source 3D printers which consistently ranks among the [best printers](https://all3dp.com/1/best-3d-printer-reviews-top-3d-printers-home-3-d-printer-3d/) money can buy. The printer currently costs about 800 Euros which is slightly on the pricey end.

-   Observing the build quality of several Prusa printers built in our Open Lab at the HSU, the build isn't one of the sturdiest out there. One possible upgrade to increase the frame strength and make the printer more sturdy is the [bear upgrade](https://github.com/gregsaun/prusa_i3_bear_upgrade), which is an all aluminium frame upgrade for the Prusa i3MK3 costing about 80 Euros bought as a kit. Moreover, most parts cannot be sourced locally, i.e. they **have** to be bought from Prusa.
