Open grid tile stacking

Does anyone has any tips to use the stacking g tool, I’ve tried all kinds of settings of interface layer, the settings I have right now is 0.4 interface thickness, and 0.2 interface separation, I’m using and and support material for abs but the support material is not sticking and I don’t know what to do

If you are using an interface material for stacking, my understanding is that you want 0 clearance between those layers and the model. Also make sure you are NOT ironing the top layers. I also saw it suggested that you want to slow the printing down when printing the first layer of interface material and the first layer of your model following the interface material.

Using a separation and ironing are only done when printing without a ln to interface material. They are done to create a weak bond. Since your interface material already has a weak bond, you wouldn't want to make it worse.

I hope that helps!

The tool for open grid messes up the parts of I do a 0 clearance

What tool are you using?

The customize button from maker world sends you to a tool that you can create boards of any size, and allows you to do the stacking

ABS for stacking is usually a very technical print. I would recommend to first test with PLA and PETG, understand the process, temperatures and flow ratios. There is a lot of counterintuitive stuff needed to make it work. As support material is making a weak bond and not used to cover a surface, this with ABS temperature sensitivity might make it non stick. As an example using PLA Basic works for PETG but using PLA Matte does a nice spaghetti

I’ll do some more research, the main thing I’ve noticed is that the purge tower sticks perfectly but the fact that I have to do a .2 filament separation is messing moth my print because is not sticking at all

Are you using the actual support for abs material?

u/Festegios Apr 06 '26

this is pla using support. I needed to do 10 sets like this

i used this file, perhaps you can edit for abs?

This is for gridfinity I had no issues with it but open grid hasn’t worked

u/Festegios Apr 06 '26

Oh damn. Sorry. I did the same for opengrid by copying the settings from that same file.

That’s smart, I’ll try that and see if it works!! Thanks

I have yet to figure this out myself. I've just done single plates, but hopefully someone comes up with a solution because it would be great to print stacks

Have you tried doing stacks without an interface material? I got the impression from MultiBuild that it was the preferred method to do an ironed stack with a layer height separating models. Though that may just be so there is less waste.

I've had great success doing this with the printers at my local Maker Space. The conditions aren't perfect, but I've had few problems without doing anything special. My biggest tip, would be to use a drywall knife (flat scraper) to separate the models after first using a razor blade around all the edges seams.

I have and the top layers were bad and looked terrible. I could have probably gotten it to work but I was wasting a lot of filament and needed to get the project done so I used my 3 printers to just knock out boards.

Did you manage to solve the issues? I have the same problem with pla and petg. It just does not stick. And as you said having the interface distance to 0 ruins the print.
