Small laboratory 50mL beaker from polypropylene

Premise

Sometimes glass is not the best material in laboratory. Specifically if you work with resins or materials which could destroy the glassware. For this reason polypropylene (PP) equipment can be used. This beaker serves mainly as a test subject for exploration of polypropylene printing properties and to achieve high quality prints before moving to more sophisticated equipment.

Printing

Polypropylene is perhaps more difficult to print than traditional materials like PLA or PETG mainly because in order to achieve quality print, one must print slowly and at high temperature to ensure proper melting of the plastic. Additionally, PP doesn't stick to most materials and it is best printed on a PP packing tape or a plate of polypropylene. 

My recommended settings are 260°C for printing temperature with volumetric speed limited to about 3mm^3/s (this can be increased with better part cooling solution). More importantly than volumetric speed is a sufficient layer time as this plastic cools down remarkably slowly and thus needs to not be overloaded by subsequent layers to prevent deformation. Don't let yourself be surprised if the first print won't work well. I went through many failed or sub-optimal prints before coming to correct conditions - however, all test print showed that high temperature is crucial for good printing. I am using Centaur PP from FormFutura which works well and doesn't seem to have any unnecessary additives. 

No heated chamber is required and even even my old Ender 3 of Theseus is fully sufficient to obtain great parts.
