S-maker: scara type desktop 3d printer prototype. April 08, 2013 03:31PM |
Hi.
I'd like want to share with you guys the development of a desktop Scara 3d printer that i have started a few weeks ago.
I call it (for now) the s-maker.
I have created a blog were you can learn a little more about it.

Here is a little video showing its first movement :

Please comment. Any feedback is welcome.

The assemble is quite rigid... will see if enough.
In fact, when i apply pression, what gives a bit is the wheel and not the arm.
The aluminium tubes are 12mm diameter and the joints are small and printed in PLA (more rigid than ABS).
But i'll have to conduct some more tests to see if it's rigid enought for printing.
I am fairly optimistic....

anything new here?

I like the static bed for scaling up to a larger build area. This seems like a design that could become an upside-down T, where a mobile bed drives itself into position, and then drives away with the printed part when done.

It's quite identical to Quentin Harley's RepRap Morgan, except that you move the head, while Quentin moves the bed.
I like the principle in your design as well as in Quentin's, because it has so much potential for expansions and improvements, while being inexpensive and simple.
Drawback in your design will be the reduced precision on mid levels of the print, because
- the weight of the arms will bend the z-axis-rods (slightly, but noticeable)
and
- the movement of the arms will cause more tremor on the z-axis.
What I like on Quentins design over yours (excuse me for that, nice work of yours anyway ) is the fixed place of driven components through the print and the reduced amount of moving masses. Only the platform moves up and down, what Quentin uses to balance the slight difference in toolhead-height between folded and unfolded arms (a point that you can integrate in your firmware with no changes to your design, by the way).
Nice build. I like scara robots.
