Resins are the perfect 3D printing materials if you are looking for smooth surfaces, high-quality, detailed prints and a wide variety of finishing and post-processing possibilities. Generally, resin is more expensive. The average 3D printer material cost for standard SLA resins is approximately $50 per liter. For some provide the best possible surface finish and special material properties like dental or ceramic resins, they can cost more. So saving considerable amount of resin material will be equal to save time and money. There are lots of ways to economize on resin costs, but here are five that you may have overlooked. Hollow out 3D models 3D printing materials is volume-based: the less the volume, the less the cost. To hollow out 3D models is meaningful. Two things to note are wall thickness and escape holes. Pushing the wall thickness to the minimum might seem like a way to save money. However, making walls too thin can make a model too fragile and might cause parts of it t...
