Print quality and filament

I am new in tris forum!
I am printing in high quality with HIPS
Veri good print but 700 g of filament gone with two printing works
I am using 50% infill
What may be a good compromise between quality and no wasting material?
I am printing not for a company.
Thank you

Hello Andrea,

I would suggest choosing higher layer thickness (0.19 mm); for large prints with no precise details, you can set 0.29 mm one. Also, set a lower layer thickness, normal/draft print quality. If possible - you could set lower support angle (only if you are sure the model will not collapse then). Editable support might do the trick as well.

Best regards
