In the last years, a lot of attention has been paid to the technology of the 3D printer since its availability for home and office use. The 3D printer allows for the making of objects by laying down plastic filament layer by layer. This project explores how different filaments and fill patterns affect the strength… Read Article →

Motivated by findings in a previous science project about the strength of different 3D printer filaments, this study explores the effect of colorant on the strength of polylactic acid (PLA), a biodegradable filament made from sugar cane, corn or yuca root. In the earlier research, it was found that objects printed with PLA and with… Read Article →
