This go-kart housing is 3D printed on a 1:1 scale. We could not help sitting inside the enclosure and pretend driving it furiously! We could print large-format automotive parts, but to ensure dimensional accuracy, split and joint would be a better solution.
Solution
Step 1: As the go-kart frame is 1.6m-long and 0.6m-wide, not exceeding our build volume of 2.4m*0.8m*0.8m, and the client is not strict on the shape accuracy, so we recommend printing the whole frame with our industrial SLA printer.
Step 2: We arrange the model in software and add necessary supports. Then 3D print it with SLA Durable Resin. The layer thickness we set is 0.1mm.
Step 3: When printing is completed, rinse the models with IPA and post-cure them with UV. Cut off all the supports, then polish with sandpaper. Cover the parts with black paint and clear acrylic to prevent yellowing.
