KRAGA Maripi - testing parts

pinshape

This is a piece of horizontal stabilizer and a piece of fuselage from the 3D printed RC plane KRAGA Maripi. If you're able to print this part, you should be able to print the whole plane. KRAGA Maripi is a 1.1m big acrobat that's printed on a 3D printer and reinforced with carbon spars. More information can be found at https://www.3DprintedRCplanes.com/maripi. A video of the assembled plane can be viewed at https://www.youtube.com/watch?v=T8RgL5h8tJ0&t. The file is also available here: https://3dprintedrcplanes.com/download_test/maripi/. Rafts: Yes. Notes: The red part has to be printed as a shell with 0% infill and no horizontal surfaces. The thickness of the shell should be one layer. This is the only way to achieve the required weight of the plane. The grey part has to be printed as solid with 100% infill. Nozzle: 0.4 mm Layer thickness: 0.19 mm Rafts: yes Use the default orientation and whatever printing material. Result verification: The red part should weigh 8 g. The wall of the shell should be printed in one pass by the printing head, so that the shell is very thin. You should be able to fit carbon tubes with a diameter of 3 mm and 2 mm into the spar leading holes. The grey part should weigh 16 g, and you should be able to fit a carbon tube with a diameter of 2 mm into all four spar leading holes. There may be small printing imperfections that make it difficult to insert the carbon spar all the way through the part, but in the written build guide, I'm describing a way to clear the holes using for example a spoke from a bicycle wheel. I strongly recommend covering both parts with a covering film to test if the material of your choice will not deform from ironing heat and if the covering film will stick on it. I've tested many materials with multiple covering film brands without issues, but it can theoretically happen.
