For experimentation purposes, I bought a Printrbot JR 3D printer when the wooden model was still being sold (v1).
Since then, I've been able to fine-tune the printer to reliably print with 0.3 mm layer heights and sometimes print at 0.1 mm.
Over the past years I've performed minor updates, mainly replacing the printbed (first to acrylic (which melted), then to 4130 steel), and updating the firmware.
I have since upgraded to a newer printer, but even with this older printer I was able to reliably print with it due to knowing the limitations and strengths of this design.
To reliably print with this printer, I have used the following settings:
|Parameter ||Setting ||Units |
|Heater Temp ||196-200 ||OC |
|Perimeter Speed ||60 ||mm/s |
|Small Perimeter Speed ||60 ||mm/s |
|Infill Speed ||80 ||mm/s |
|Support Speed ||90 ||mm/s |
|Bridges Speed ||90 ||mm/s |
|Gap Speed ||30 ||mm/s |
|Travel Speed ||130 ||mm/s |
However, those settings are only applicable when using either Repetier-Host
or Matter Control
to load up the STL file, Slic3r
to slice the file
into layers, and either program to send the slices to the 3D printer for printing.
To actually design the models to 3D print, I either use an existing model on Thingiverse
or design my own.
Designing a 3D model can be done with a variety of software:
At the end of the day, the software isn't what makes a good design. A good design comes from a good idea and the commitment of time to implement it, along
with the tooling to express the design effectively. One great example of this is the Printrbot's laser-cut parts -- there are many parts, but
they all work together to allow you to make more parts of your own design.
