ERRF 18: Slice Engineering Shows off the Mosquito

Posted on by

With few exceptions, it seemed like every 3D printer at the first inaugural East Coast RepRap Festival (ERRF) was using a hotend built by E3D. There’s nothing inherently wrong with that; E3D makes solid open source products, and they deserve all the success they can get. But that being said, competition drives innovation, so we’re particularly interested anytime we see a new hotend that isn’t just an E3D V6 clone.

The Mosquito from Slice Enginerring is definitely no E3D clone. In fact, it doesn’t look much like any 3D printer hotend you’ve ever seen before. Tiny and spindly, the look …read more

E3D Introduces Tool Changing 3D Printer

Posted on by

E3D has introduced their latest answer to multimaterial printing at the Midwest RepRap Festival this weekend. Their research project into a 3D printer with the ability to change toolheads is the latest advancement in multimaterial printing. It’s a work of engineering brilliance, and they’ve already written up their teardown on how this all came to be.

While milling machines and other fancy industrial CNC have had tool changing for decades, and the subject has been pursued by the RepRap community for a few years now, it really hasn’t caught on. The question then is, what is tool changing on a …read more

Hipster hardware! [Bunnie] found something interesting in Tokyo. It’s a LED matrix display, with a few PDIP chips glued onto the front. There are no through-holes or vias, and these PDIPs can’t be seen through on the back side of the board. Someone is gluing retro-looking chips onto boards so it looks cool. It’s the ‘gluing gears to everything therefore steampunk’ aesthetic. What does this mean for the future? Our tubes and boxes of 74-series chips will be ruined by a dumb kid with a hot glue gun when we’re dead.

Is it Kai-CAD or Key-CAD? Now you can …read more

Water Cooling a 3D Printer

Posted on by

It may seem like a paradox, but one of the most important things you have to do to a 3D printer’s hot end is to keep it cool. That seems funny, because the idea is to heat up plastic, but you really only want to heat it up just before it extrudes. If you heat it up too early, you’ll get jams. That’s why nearly all hot ends have some sort of fan cooling. However, lately we have seen announcements and crowd-funding campaigns that make it look like water cooling will be more popular than ever this year. Don’t want …read more

The Engineering Analysis Of Plastic-Dissolving Lubricant

Posted on by

Over the years, E3D has made a name for themselves as a manufacturer of very high-quality hotends for 3D printers and other printer ephemera. One of their more successful products is the Titan Extruder, a compact extruder for 3D printers that is mostly injection-molded plastic. The front piece of the Titan is a block of molded polycarbonate, a plastic that simply shouldn’t fail in its normal application of holding a few gears and bearings together. However, a few months back, reports of cracked polycarbonate started streaming in. This shouldn’t have happened, and necessitated a deep dive into the failure analysis …read more

MRRF 17: E3D Introduces Combination Extruder And Hotend

Posted on by

Since the beginning of time, or 2006, the ‘hot glue gun’ part of our CNC hot glue guns have had well-defined parts. The extruder is the bit that pushes plastic through a tube, and the hot end is where all the melty bits are. These are separate devices, even though a shorter path from the extruder to hotend is always better. From Wade’s gear extruder to a nozzle made from an acorn nut, having the hotend and extruder as separate devices has become the standard.

This week at the Midwest RepRap Festival, E3D unveiled the Titan Aero. It’s an extruder …read more

Soluble Molds For Composite Parts

Posted on by

People have been experimenting with 3D printed molds for fiberglass and carbon fiber for a while now, but these molds really aren’t much different from what you could produce with a normal CNC mill. 3D printing opens up a few more options for what you can build including parts that could never be made on any type of mill. The guys at E3D are experimenting with their new dissolvable filament to create incredible parts in carbon fiber.

For the last year, E3D has been playing around with their new soluble filament, Scaffold. This is the water-soluble support material we’ve all …read more

The Travelling Hackerbox is going International. I wrote a post on this earlier in the week, and I’m still looking for recipients for the box that are not in the United States. The sign-up form is right here, and so far we have good coverage in Canada, Australia, NZ, Northern Europe, and a few in Africa. If you ever want to be part of the Travelling Hackerbox, this is your chance. I’m going to close the sign-up sheet next week. Sign up now.

Like the idea of a travelling hackerbox, but are too impatient? Adafruit now has a …read more

DIY Nozzle Socks For Your 3D Printer

Posted on by

If you have a 3D printer, your nozzle and heater block are invariably covered in a weird goo consisting of decomposed and burnt plastic. There’s only one way around this – a nozzle sock, or a silicone boot that wraps around the heater block and stops all that goo from accumulating.

Right now, E3D sells silicone nozzle socks for their normal-sized heater blocks, with a release for their maxi-sized Volcano blocks coming shortly. [Ubermeisters] couldn’t wait, so he designed a 3D printed mold to cast as many Volcano nozzle socks as he could ever need.

The mold itself is taken …read more

Nozzle socks! Just keep saying, ‘nozzle socks’ until the semantic satiation undoes any semblance of sanity. E3D, makers of the world’s finest 3D printer hotends have released silicone nozzle covers that prevent caramelized plastic gunking up your hot end. Nozzle socks.

Let’s talk guitar pedals. If you’ve ever built your own guitar pedal, you probably stuffed it inside a Hammond enclosure. There’s more to guitar pedal enclosures than custom-painted electronic boxes, and arguably the best enclosures are the ‘Boss’ style – a metal cover over the switch that can be removed to access the battery independently of the circuit. Now …read more
