Precision Prints with Peachy Printer

I was thinking that it certainly has the resolution for it. Just look at the Z axis. If you had a print area of 200x200 mm and 20 drops of water is equal to 1 ml, then that is 0.00125 mm accuracy. People freak out about 0.1 mm Z height accuracy, this is 100 times that. Pretty impressive.

I also had some thoughts on the galvanometer setup. It is a Tangent style galvo. That means that 0 degrees and 90 degrees position of the magnet requires the most amount of energy for a given movement. So it isn't linear, but the software can compensate for this. But, the magnet angle could be placed at a 45 degree angle. And the movement could be roughly 25 degrees each way off that starting position. That puts the galvo in the most sensitive and most linear portion of its range.

Another thing I noticed when I began thinking more of how the peachy prints is that the more intricate and complex a layer gets, the resolution must be increased further to compensate for the extra time it takes for the laser to complete it's path. before it begins the next path otherwise there might be gaps in between the layers of cured resin.

So in theory the more complex the print you need to decrease the amounts of drips to compensate for the laser.

that also means you need to calibrate allot by hand to get the right resolution depending on the complexity of the print.

Not sure if this would work or not, but I was considering in the case of a layer which requires a longer build time, that I would use a larger container. The idea being that a bigger container would take a longer time to fill giving the time required to draw a time intensive layer, granted this would increase the overall build time and the amount of resin required but I thought it was a simple solution. Other then this as the others have mentioned here I was gonna have a go at controlling the drip rate to speed up or slow down the transition between layers.
