Model notes · 01

Second RepRap design

Mendel succeeded Darwin with a smaller footprint and revised Z-axis constraints. This record describes Ed Sells’s original Mendel rather than later Prusa or other derivatives.

What the performance numbers mean

The project page’s deposition result is a solid-PLA example. Its much higher listed XY motion limit is not sustained print speed, and positioning accuracy is not a general finished-part tolerance.

Read this with the specifications

Open design specifications describe the original Mendel; individual builder configurations can differ.

A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
