Let’s say that printing with soluble filament is not an option and that you have already reduced the number of supports to as low a number as possible. If you’re using a filament that prints at temperatures close to either PLA or ABS, then there is probably room for some experimentation. Based on their printing temperatures, PVA is an appropriate co-filament with PLA, while HIPS is for ABS. There are two options for soluble filaments – Polyvinyl Alcohol (PVA) and High Impact Polystyrene (HIPS). It is possible to switch filaments manually, but this will probably be more trouble than it’s worth. This allows for automatic and seamless switching between two different filaments. First off, you will need to have a 3D printer with a dual-extruder setup. There are several conditions for this option to be available.
It takes virtually no effort and is less likely to cause damage to your print. There is no easier support removal step than simply submerging your finished print in the appropriate solvent. If you have the option to print your supports with soluble filament, then go ahead and do it.
This translates to less waste and a shorter printing time. Since you will be printing fewer supports, you will inevitably also be using less filament.
Reducing the number of supports also offer a few other benefits. If you can reduce the number of supports by even 10%, then that’s already a win in our book. Take advantage of the 45-degree rule for determining when and where a support is needed. The easiest way to do this is to play around with the orientation of your model in the 3D space to hopefully reduce the number of necessary supports. We then have to go to the next best thing – to use as few of them as possible.
The best way to reduce the difficulty of removing supports is to not use them altogether. Check out these tips on how you make the support removal step a little easier. If you’re printing a design that has a complex geometry, the best that you can do is to design your supports so they can be easily removed. You will also want to have a set of the proper tools for support removal.ģD printed supports can be annoying, but they are necessary. There are several slicer options that can be adjusted to help towards this goal. Most of the work needed to make support removal easier has to be done before the actual printing.
