Hi Tim_111

66cm is pretty large for common 3D printers.

It would help if you would be able to take a photo of a napkin sketch of what you wish to accomplish.

Even at a size of 33cm, your project would still be pretty large.

It could possibly be broken into smaller parts that could be assembled with glue or screws.

If you could attach a sketch, I think you would get responses from 3D Hubbers.

I hope that helps you out.

I attached the model and a image. would you think it would be cheaper to get it laser cut locally?

Also what type of plastic would be best thats food safe and would not bend out of shape over time?

Cheers

Thanks for your reply. i really found drawing that simple structure challenging lol.

I can’t really view the model right now, but assuming it fits the prerequisites for laser cutting (must be made from either a single flat sheet or stacked flat sheets) it might indeed be better to have it laser cut. 3D Hubs charges by volume, and a 66cm part’s volume would be quite massive even if you could find a hub able to print it for you. Laser cutters (at least around where I live) usually charge per job, and size doesn’t have nearly as much of an effect on the price than it does with a 3D printing hub.

Also, food safe is a property that actually depends about as much on how a material is processed as it does on the material itself, and honestly 3D printing is not good for food safe products. The crevices between each individual layers are breeding grounds for bacteria, and aren’t really easy to reach when being washed. In that regard I do imagine laser cutting to be a better option for food safety, though with laser cutting the issue might be finding a food safe material to cut in the first place.

Hope this helped!
