3D printing is all well and good for making low numbers of units, so long as they’re small enough to print in a reasonable time, but what if you want …read more Continue reading Fast 3D Printing With a Polar, Four Quadrant Custom Machine
3D printed parts are generally no way near the strength of an equivalent injection moulded part and techniques such as a sustained heat treatment, though effective usually distort the part beyond use.
[CNC Kitchen] was investigating the results of a recent paper, that described a novel ABS filament reinforced by …read more

The last three days marked the 2018 Midwest RepRap Festival. Every year, the stars of the 3D printing world make it out to Goshen, Indiana for the greatest gathering of 3D printers and printing enthusiasts the world has ever seen. This isn’t like any other 3D printing convention — everyone here needs to take the time to get to Goshen, and that means only the people who want to be here make it out.
Over the weekend we covered some amazing hacks and printer builds from MRRF. The ‘BeagleBone On A Chip’ has become a complete solution for a 3D …read more

The Prusa i3 Mk 2 is the hotness in consumer-grade, quality 3D printing right now. And things just keep getting more interesting. We caught up with Josef Průša at Maker Faire Bay Area this weekend to see the multi-material extruder in its final form. It’s an upgrade to the Mk 2 which allows a single hot end to print in four different materials, be it different colors or different types of filament.
Jo has a reputation for turning out some of the most clever and dependable design improvements to 3D printers. Just one year ago he …read more

Let’s talk multi-material printing on desktop 3D printers. There are a lot of problems when printing in more than one color. The easiest way to do this is simply to add another extruder and hotend to a printer, but this reduces the build volume, adds more mass to the part of the printer that doesn’t need any more mass, and making sure each nozzle is at the correct Z-height is difficult. The best solution for multi-material printing is some sort of mixing hotend that only squirts plastic from one nozzle, fed by a Bowden system.
[Prusa], the man, not the …read more
