In previous posts I built a prototype ‘TandemB’ which can be thought of as a 2D Delta printer in terms of its x and y-axis movement. This prototype could be moved about under its own power but that had no compatible firmware … Continue reading
In a previous post I proposed the idea using an unconventional kinematic system to translation movements in the x and y axis. This idea, which was dubbed ‘Tandem’, is similar to that of a delta robot with the key difference being that rather … Continue reading
Working in Tandem – Unconventional XY-axis layouts for 3D printing, laser cutting, CNC milling, engraving or pick and place.
Below I outline three separate concepts for moving in the X and Y plane with a specific emphasis on minimising the moving mass, maintaining high mechanical stiffness, reducing backlash and allowing two stepper motors to work in tandem. It is my hope that these concepts, … Continue reading
How to take an image like this: and in one step generate the gcodes required to do this: All credit for cad.py goes to the original creator Neil Gershenfeld of MIT Center for Bits and Atoms and David Carr of Make Your Bot who optimised the … Continue reading
For quite some time I have lusted after a 3D printer with the following specifications: A 20x20x15cm build area A heating print bed A heated build chamber (ambient to 100C) to possibly eliminate warping. A respectable print resolution and speed … Continue reading
The holy grail of a self replicating 3D printer is the ability to print its own drive train. In the long term this may be possible with some form of multi-metal stintering system that can produce a stator layer by layer. However … Continue reading
I recently came across this industrial grade meet grinder. Its located in a laboratory used for, among other things, injection moulding. I’m told that its used to grind plastic granules down into a fine powder. What is particularly interesting though is … Continue reading
