Collaborate Disseminate
Here we are in the future, thinking we’re so fancy and cutting edge with mega-scale 3D printers that can extrude complete, ready-to-occupy buildings, only to find out that some clever …read more Continue reading Retrotechtacular: 3D-Printed Buildings, 1930s Style
[Thomas Sanladerer] wanted to create some molds using 3D printing for concrete and plaster. He used a delta printer with flexible filament and documented his process in the video below.
If you’ve printed with flexible filaments before, you know you need an extruder that has a contained path. [Tom] borrowed a printer, but it didn’t have that kind of set up. The first step was to swap extruders with another printer.
Some scrap wood made a box for the positive model. [Tom] used a concrete-based mortar since he didn’t have real concrete ready for this test piece. However, his ultimate …read more
