MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
You will need to do your own research on food safe filament as not all manufacturers have standards they adhere to. HoweverI've never had any concerns with the MakerBot PLA I use as they have quality controls in place with MSDS reports available.
Having said that PLA is produced from plant based resins and it's obviously hot enough to kill any bugs when extruded. I have to think the bigger risk using this for food is keeping it clean as particals could get into fine spaces / ridges in between layers. Look at a print with a magnifying glass and you will better appreciate this point.
