Some of the additives used to create colors can also be somewhat toxic. Many filaments have proprietary chemical additives to make them more flexible or give better extrusion characteristics. For holding liquids, more should be done. Printing as described here will result in solid prints which are easier to clean and less friendly to bacteria.įor storage or measurement of dry foods, most PLA printing filaments can probably be used without problems.
Normal 3D prints are fairly porous leaving lots of micro spaces for food and bacteria to accumulate. Here are the essential settings used, all other settings are left at default: twice as fast extrusion speeds as detailed here can be used, and they will seal, but they tend to result in less smooth prints. This allows for the extrusion to be wider and overlap side by side layers. In order to over-extrude, the print speed has to be slowed down and the extrusion multiplier increased. Most extruders are designed to do a clean print as fast as possible. In order to get prints that are waterproof and airtight, the slicer settings have to be adjusted to over-extrude the filament.
Other slicer programs can be used, but the settings will have to transferred over, which can be difficult as different programs use slightly different terminology for the settings. You may have to make some adjustments of the settings for other 3D printers.
BEST 3D PRINTS FREE
I have had very good results using the free Mattercontrol slicer to slice prints for a Makerbot Replicator 2.

A slicer is the program that is used to tell a 3D printer how to print an STL file.
