Before even printing the person needs to do to get good 3D models is by drawing and preparing the 3D model in the right way and the same machine can give different results in printing depending on various factors and one of these factors is orientation of the object which can significantly improve the solidity of the model and it also reduces or entirely avoids supports. Generally supports are generated when the overhang is more than 450 to prevent the collapse of the structure and in some cases, if the model cannot be made without the supports then the person can use other software to draw them to optimize the printing process and the other thing to consider is that using little or no support means that there will be less material used in print and a lower post processing time.
The other way to reduce solid works 3D printing is to use suitable G-code parameters for the model because decreasing the percentage of infill in the print will not only reduce the plastic the person needs by almost a quarter but it will also minimize the solidity of the objects and it is not always that someone needs a very high infill especially when it comes to decorative prints and other stuff like pen holders, vases and other things. An important fact to note is that the person printing can also use higher layers, which may lead to a loss in some quality hence the person needs to have a balance between quality and costs and they can study various case studies to determine where they can strike this balance.
The person has to use the right filaments and in most cases, exotic filaments are used because they are cool, but their demerit is that they are more expensive than the standard ones and thus the person should only use these filaments when they only need specific effects. If that is the case then they can consider buying them in samples of about 250 grams instead of big spools and it is good to note that almost every major filament manufacturer offers samples that are quite helpful for small and two-material prints or the person can search the web for cheaper filaments online, but they might contain impurities that will add bad effects to prints.

If the person is printing many objects they may need to buy bigger spools or placing big developer orders that are sold at a lower price per kilo and there is the alternative of making their own PLA or ABS filaments from pellets but the demerit is that this would require one to buy an additional machine. A known fact is that following the tips above will enable the person make significant savings in their printing jobs. Read here for solidworks forum!
