A same wall thickness for different resins like rigid resin and flexible resin may result in different print quality. Left: 5mm wall thickness Right: 2mm wall thickness. I have tried hex-grid infill and pillars. You can orient it identically to your preset in PreForm, if it makes it easier to find the correct location for the vent holes (Edit > Transform). By default,stereolithography (SLA) 3D printerscreate fully dense parts. You can orient it identically to your preset in PreForm, if it makes it easier to find the correct location for the vent holes (Edit > Transform). And in latest ChiTuBox 1.5.0, hole depth is available to be customized for models with different depths. This process will continue in a cycle until the entire object is formed layer by layer. It comes in seven different colors, is very flexible, and provides a smooth finish to any piece. Some parts of the model are too thin. Often they have very thin details.
