Additive + Subtractive = One Powerful Machine

Posted on by

It says it right on the title of the video below: it was bound to happen eventually. It’s only natural that somebody would stick a 3D printer extruder on the business end of a CNC machine. The long-awaited convergence of additive and subtractive manufacturing is here.

OK, that may be overstating things a bit, but we think [Chris DePrisco] is on to something here. Given the considerable investment he’s made in his DIY CNC machine, an enormous vertical machining center that looks a little like a homebrew Bridgeport, it was a no-brainer to take advantage of the huge XYZ stage. …read more

Much More Than a Desktop Mill: The DIY VMC Build

Posted on by

A VMC (vertical machining center) is essentially a CNC vertical milling machine on steroids. Many CNC mills are just manual milling machines that have been converted to CNC control. They work nicely, but have a number of drawbacks when it comes to real world CNC milling: manual tool changes, lack of chip collection, lack of coolant containment, and backlash issues (which a manual machinist normally compensates for).

These problems are solved with a VMC, which will usually have an automatic tool changer, and an enclosure to contain coolant and wash chips down into a collection pan. They are, however, very …read more

Japanese Lab Builds 5-Axis 3D Printer

Posted on by

A Japanese lab is investing some time in the possibilities of a 5-axis 3D printer. They show it printing using five axis as well as doing finish machining on a printed part. We’ve covered parts of why this is the right direction to go for 3D printing in another post.

It looks like they have modified an existing industrial machining center for use with a 3D printing nozzle. This feels like cheating, but it’s the right way to go if you want to start playing with the code early. The machines are intensely accurate and precise. After all, building a …read more
