"granules from recycled thermoplastics print 8X faster with screw extension additive manufacturing, saves 10% weight and material costs... delivery payload capacity 200 kg including rider... production costs 200X lower... rugged shelf and vehicle frame individually shaped and high load-bearing capacity... 3D-printed rear shelf reduces weight while optimizing cargo space. saves 26.5 kg compared to previous retrofit while shelf system unchanged, lower drawer bears 100 kg... 8% more storage area"
