When we test any of our cutters or even for the physical cutters we sell, we use the Da Vinci Mini Wireless by XYZ Printing. This was the first 3d printer we ever purchased, we have used a few others, but the Da Vinci Mini is the one we always use.
The software is pretty basic, great for beginners, and works perfectly for simply uploading our cutters and printing. Even easy enough for older kids to use it (with adult supervision of course).
You can use the pre-defined settings or open the advanced settings option, we have worked with both, but tend to use the pre-defined settings for our cutters. It's up to you which settings you use based on the filament you use.
The print bed is 6" x 6", so when printing a 6" cutter, you will need to fit to bed making it just slightly smaller than 6" or turn them different ways, which is why we often tell people selling cutters to put a size error disclaimer on their listing or website. We don't sell many 6" cutters and the ones we do haven't had any complaints. 6" is pretty big for a cookie :)! The standard size for a cookie cutter is approximately 3", with 2" and 3" being our most popular sizes.
This printer is also wireless, so it doesn't have to be connected to your computer constantly when printing. We have our Da Vinci Mini on it's own little shelf behind our desk with all of our filament conveniently located underneath it on separate shelves.
The one downfall we've had with this printer was the filament, if you want to use third-party filaments, filaments not by XYZ, you will need to buy an Open Smart Tag.
The Open Smart Tag is pretty simple to use and install, we simply used a piece of tape and taped it on to the filament holder on the printer, so it doesn't fall off. We believe this is a must have item with this printer!
If you do it this way you won't be able to use the printer holder for your actual filament and will need a different place for your spool.
XYZ Printing also carries more printers and accessories that you can check-out for yourself! We'd love to know if you use the Da Vinci Mini Wireless by XYZ Printing to print our cookie cutter files and if you like it!
