Want some flexible circuits? OSHPark is testing something out. If you have an idea for a circuit that would look good on Kapton instead of FR4, shoot OSHPark an email.
SeeMeCNC has some new digs. SeeMeCNC are the creators of the awesome Rostock Max 3D printer and hosts of the Midwest RepRap Festival every March. If you’ve attended MRRF, you’re probably aware their old shop was a bit on the small side. As far as I can figure, they’ll soon have ten times the space as the old shop. What does this mean for the future of MRRF? Probably not much; we’ll find out in February or something.
If you’re looking for a place to buy a Raspberry Pi Zero or a Pi Zero W, there’s the Pi Locator, a site that pings stores and tells you where these computers are in stock. Now this site has been expanded to compare the price and stock of 2200 products from ModMyPi, ThePiHut, Pi-Supply, and Kubii.
MRRF, the Midwest RepRap Festival, is in full swing right now. The venue is packed, attendance is way up this year, and the panorama is impressive:
MRRF is not really a trade show. Yes, there are companies here (Google is picking up the tab for Chinese food tonight), but this is assuredly a community-based event around open source hardware. That said, Lulzbot is here, SeeMeCNC is hosting, E3D, and Ultimachine are all here. This year, there are a few new printers.
Lulzbot’s Taz 6 – the latest update to their flagship printer made its first public appearance at MRRF this year. A product update from Lulzbot isn’t like a product announcement from a normal company. Lulzbot is using rapid prototyping for manufacturing (!). They can iterate quickly and release two new printers in the time it takes Stratasys to come up with a design. This also means the releases are incremental.
Walk in to the science center at Maker Faire this year, and the first thing you’ll see is a gargantuan assemblage of aluminum extrusion spitting out molten plastic for one of the biggest 3D prints you’ve ever seen. It’s SeeMeCNC’s PartDaddy, a 16-foot tall 3D printer with a four foot diameter build plate.
The printer doesn’t extrude filament. Instead, this printer sucks up PLA pellets and extrudes them with a modified injection mold press mounted to a delta printer frame. That’s a 4mm nozzle squirting plastic. The heater for the extruder is 110 V, and the NEMA32 motors are controlled with 72V drivers. Everything about this is huge, and it’s surprisingly fast; a single-wall vase grew by about two feet in as many hours. We have no idea how fast a solid print can be completed, although the SeeMeCNC guys will probably find out later this weekend.
SeeMeCNC also had a neat little resin printer with an impossibly clever name on display. We’ll get a post up on that later this weekend.
