Note: This article contains advanced information regarding PP. The default settings for our BCN3D PP have been tailored for good quality and reliable results, and are fully tested by our laboratory. These tips complement those settings to ensure the best quality in printing with PP.

PP (Polypropylene) is a thermoplastic polymer that features a high chemical resistance and stability, and makes it great to manufacture parts that have to be in contact with food, chemical agents or outdoors. Microwaveable food containers, outdoor furniture and surgical meshes for various kinds of surgeries are some of its main uses.

Make it stick and know how to remove the print

Getting the first layer well stuck in PP is challenging as it tends to warp up and unstick from the hotbed. Apply a good amount of Magigoo PP glue on the printing surface where the model should be printed. For bigger models, if Magigoo PP cannot keep the PP stuck on the glassplate., you can use Magigoo PPGF for increased adhesion. 

 


Before taking out your finished print, let it cool down as slowly as possible so it contracts uniformly and the tensions are mellowed. Once it is cooled, remove the print carefully. Here are some more tips that will help you in removing your prints:

How to safely remove prints

 

Better looks

PP is translucent, this means that if you print it with infill, this will be visible. If you want your parts to look better, increase the wall line count and set the infill percentage to 0% when possible to give your part a better quality look. 

 

Printing with supports

When printing small parts that require support,  let the overhangs cool down to prevent them from deforming and overheating. You can achive this by printing a denser support structure or setting a minimum layer time of 30 seconds. 

 

Take advantage of hinges

PP has a unique capability of creating live hinges, this means that if you print a thinner part in the model, this can be bent to create a hinge with high durability, this is specially useful when creating compliant mechanisms or lidded boxes. 

 

In terms of design and placement, you should place all the hinges flat on the buildplate, a thickness of 0.4mm in the model should work great.
