High grade aluminum DIY syringe extruder by Liam Gilbertson

DIY syringe pumps and other syringe devices are used in different 3d printing projects for depositing various materials from living cells to solder paste dispensers.
Liam Gilbertson posted a very detailed tutorial on how to build your own syringe extrude from MendelMax 2.0 or any other 3D printer based on 2020 extrusion rails.
Be aware that this is not a novice level project since the extruder is very sturdy and may require some machining knowledge and more specialized tools like laser or water jet cutter able to cut 3mm aluminum.

MendelMax 2.0 review and impressions by ZennmasterM

Great review video of MendelMax 2.0 by ZennmasterM.

MendelMax 2.0 description from RepRap wiki:

The new MendelMax 2 is a complete reinvention of the MendelMax. It makes the MendelMax faster to build, easier to source and even better looking than before.

Design
The MendelMax 2 includes a completely redesigned frame, made from aluminum extrusions and primarily flat plates. These plates can be cut from aluminum, printed, laser cut from plastic, or hand cut with a scroll saw or a coping saw (making this arguably the most accessible DIY reprap ever). A hand cut MendelMax 2 will virtually function identically to a custom machined one. There is no longer a reason to see your hand built machine as merely a means to an end.
Triangles are a smart choice for the gantry, both functionally and aesthetically. From a design standpoint, I wanted the MendelMax to still be visibly a Mendel descendent, while not letting the shape get in the way of improvements. By switching to a right-triangle design, the MendelMax 2.0 gains ~50mm more z-axis movement (the exact amount will depend on your extruder choice). The new design results in a very open, unobstructed print area.
