This profile is designed for printing IC3D PETG filament (1.75mm) on large-format 3D printers using orcaSlicer. It is ideal for makers and engineers who need reliable, high-strength prints for outdoor enclosures and large functional parts. The settings focus on delivering excellent inter-layer bonding, consistent quality, and dependable results for demanding, tall prints.
The profile is tuned for PETG’s unique requirements on large-format machines. A higher hotend temperature and heated bed ensure strong layer adhesion, while a reduced cooling fan minimizes warping and improves bonding on tall structures. These adjustments help achieve robust, reliable prints suitable for structural and outdoor applications.
Hotend and Bed Temperatures: The profile uses a 235 °C hotend and 80 °C bed, which are optimal for PETG to promote strong adhesion and reduce warping, especially on large prints.
Cooling Fan: Fan speed is reduced compared to PLA profiles, with the fan off for the first few layers and limited to a maximum of 40%. This helps PETG layers fuse better, resulting in stronger parts.
Wall Count: Three solid walls are used to increase part strength and durability, which is important for functional and structural prints.
Infill Density: A moderate infill (~40%) balances strength and material usage, making the profile suitable for load-bearing applications.
Bed Adhesion: A skirt is used to prime the nozzle and help with initial layer consistency, reducing the risk of print failures on large beds.
