i have been trying to cut acetate sheets(foil that can be used for chocolate or cakes) with the Snapmaker2 and the 1600mW laser for a few days now. Unfortunately I only have success as soon as I put a piece of paper underneath. Then both are cut. But during the cut the acetate “merges” minimally with the paper. Does anyone have a tip for me on how I can best cut this acetate film?
The film alone cannot be cut, not even at 100% power and 40mm/min working speed. It does not even leave any marks
With the paper I cut with Power 100% and a working speed of 320-340 mm/min
Assumign the Foil is clear, the laser doesnt get enought absorbed to heat teh plastice neough to cut it, the paper below allows for that. Ive seen ppls suggest, when cutting a PVC sheet to apply a black marker so the laser can heat that and then cut it, not sure if thats food save though (from your mentionign cake).
ITmaze: Unfortunately I don’t have any rice paper here, but since normal paper is “edible” I would rather continue to use this. But as soon as I go shopping again, I will test it as well.
@Streupfeffer: yes, the foil is clear. I’m just surprised, because I saw a patisseur in a YouTube video who had cut out a pattern like this. Unfortunately you didn’t see much of what was under the foil. The idea with the marker is interesting.
I have now tried 5 different markers. All of them I could be easily removed with ethanol. Then I put the color up the foil and tested it. Unfortunately the cutting results were quite bad. More melted than cut.
Then I put the color down. After that I started a new test series.
This worked much better.
In the test series I increased the working speed in steps of 20.
The best results I got with 100% power and 420mm/min working speed and 2 passes without depth increase. (Apparently 2 passes are better, so that the film does not melt but is separated)
Not Perfekt but good enough for me to work with.
If anyone have other ideas pls tell me.
The faster you can cut the less material will melt.
When I do laser tests I usually change speeds by multiples of 2, until I get to 600
So 40, 80, 160, 320, 600, 1000, 1500, 2000. (I may start at 320 depending on material and past experience) Then I may decide to fine tune between two speeds. I may also set multipass to run two passes and try that.
Hey Atom, that ist this is also possible. the idea with the parchment paper is also good. the nice thing is, that with acetate sheets the chocolate falls off by itself, no matter how thin it is.
hey adj544, yes and no. the foil is used when i make chocolate patterns. these are made on the acetate foil, and as soon as the chocolate cools down, it can be easily removed. It is also used when making cakes, for example to increase the height of the edges (for dessert rings the height is often limited).
I must apologize.
After Brent113 mentioned the plotter, I watched the video a few times and in the few frames in which the device was shown, I realized that there was a cutter device like that. So I have to reject my claim: they used that in the clip as well".
My hope is and was to cut these acetate sheets with a laser. But that is not bad if in the end it does not work as I had wished. Since I am a total beginner in Laser cutting, I had to learn what is possible and what is not.
Thanks to you, i have already found a method, which I will try out for the few uses here with the acetat sheets.
Just to be clear I meant Use parchment paper under the acetate Because it might not bond to the acetate is much is normal paper. Also I know when doing acrylic people have used spray on type paints or adhesives so that might be another option is a spray on food colouring
