nanoDLP

An update about better reinforcement structure for use in 3d printing, the spaceclaim program produces beautiful structures and shell, my favorite is this image, solves the problem of resin drain and creates an extraordinary structural strength

Normally you should be able to change firmware with one already tested in Nanodlp, (Marlin for Muve, Sprinter), or if you leave that original you need to know the control code (Gcode or some other)

Thanks Shahin ,
Of course you can put it on the page, it is still in test mode, but so far it has behaved well

maybe it does not depend on the slicing engine, but  that your 3d model has non-manifold surfaces,  so you should monitor and correct the model before slicing

The method should work as follows:

Layer n1 > full image exposure, (n.seconds), dimming image exposure, (n.seconds), peeling.
Layer n2 > full image exposure, (n.seconds), dimming image exposure, (n.seconds), peeling.
and so on

and not:

Layer n.1 > full image exposure, (n.seconds), peeling
Layer n.2 > dimming image exposure (n.seconds), peeling
Layer n.3 > full image exposure, (n.seconds), peeling
Layer n.4 > dimming image  exposure (n.seconds), peeling
and so on.

I solved the problem by using the FW of Sprinter master,
I think there is in Muve, some settings for the Fan (D9) that prevented M106

Hi Nanodlp enthusiasts ,

fantasy castle here,  50 micron Z, 66 micron XY

I use Netfabb Premium (there is also a free version "basic") to repair and transform 3d models in SLC, is the best ever (initially I used rhino)

the  detachment from the FEP sheet is by the natural elasticity of the film, you have to find the right speed of descent of the plate

44 micron XY
30 micron Z
3 Burn layer          @ 60 sec.
30  after burn layer @ 10 sec.
normal layer         @ 3,5 sec.
 

the main problems of the "top down" system are : inconstant resin level and  formation of bulges during exposure to UV rays, which produce geometric anomalies,
to solve these problems a solution is to use a pan according to the drawing

Hi Jaidek,

I used the following method (see attached pictures):
1_ raise the plate  on the resin level, but clean,
2_ from  "projector calibration" of nanodlp, active "boundary"
3_ position a sheet of paper,
4_  I draw with a pen the angles
5_  measures the longest side (eg 125 mm),
mathematical calculation: 125/1920 = 0.065 (65 microns to be set on nanodlp)
that's it, then you can make tweaks scale x / y or z (Override X / Y Resolution).
I developed a pan, however, that stabilizes the projection plane, it works very well, and just do calibration only once,
