Saving Money with Supports

Recommended Posts

Hello, so I have an idea to save the amount of PVA that is used to print supports without compromising any quality! Last time I checked, PVA is significantly cheaper than a main material like PLA. What if you printed only the bottom and top of the support column in PVA, and print the tall, wasteful part in PLA. I this way, you can through the print in a bucket of water, and the PLA column of support will break free from the part after the PVA on the top and bottom of the part dissolve away. Does anyone know how to do something like that, I would imagine that you would need to manipulate the way that Cura slices supports which sounds very hard to do.

Does this make sense? I you have any questions you can reach me at bairdbankovic@gmail.com

This feature is already in cura through the following settings:

.
Support infill extruder
Support interface extruder
 Support roof extruder
 Support floor extruder

Obviously it will not work on prints where the support material gets trapped inside the model if it can't be dissolved.

It's not as easy as just selecting the PLA extruder as 'Support infill extruder' (unfortunately). You have to change a few more settings for it to work nicely:

With these settings it should work similar to how PVA-only supports work. It won't work with every model, because the support infill structure is really strong and will often be locked inside/around the model. So watch the layer view before deciding to print with these settings :). Use the 'Support Horizontal Expansion' and 'Support Join Distance' settings to change the shape of the supports.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
