We’ve Found The Awesome Singularity

tardis

Yes, that’s exactly what you think it is. A Transformer. That transforms into the TARDIS.

This masterpiece of pop culture is the work of [Nonnef] over on Instructables. After the inspiration to create this work of art struck, [Nonnef] started modeling this Transformer and TARDIS in clay to make everything fit together just right. After a good bit of 3D modelling, the Doctor’s robotic wife was ready for printing.

If you’re going to print one of these for yourself, be prepared for a very long print. [Nonnef] says the latest version took about 30 hours on his RepRap with a .35 mm nozzle. In the end nearly the entire Transformer came directly from a 3D printer, the only additional parts needed being a pen spring and a small screw. Paint is, of course, optional.

All the files are available on the Instructable.

An Interview With [David] Of Ultimaker

cura

After interviewing the creator of Slic3r and the folks at Shapeways, [Andrew] is back again with his adventures in 3D printer videography and an interview with [David Braam] of Ultimaker

About a year ago, [David] looked at the state of the art in 3D printer control and Replicator G. While Replicator G, along with Pronterface and Repetier-Host both convert 3D models into G-code files as well as control the printer while its squeezing plastic out onto a bed. [David] thought the current state of these RepRap host programs were janky at best, and certainly not the best user experience for any home fabricator. This lead him to create Cura, a very slick and vastly improved piece of host software for the Ultimaker.

Cura isn’t just a fancy front end on an already existing slicer engine; [David] created his own slicing algorithm to turn .STL files into G-code that’s immensely faster than skeinforge. Where skeinforge could take an hour to slice a complex model, Cura does the same job in minutes.

There are also a bunch of cool features available in Cura: you can rotate any part before sending it to the printer, as well as pulling voxels directly from your Minecraft world and sending them to your printer. Very, very cool stuff, and if you’re running a Ultimaker or any other RepRap, you might want to check it out.

An Interview With Shapeways

June 11, 2013 by 11 Comments

It seems [Andrew] is an up and coming historian for the world of 3D printing. We’ve seen him interview the creator of Slic3r, but this time around he’s headed over to Eindhoven, Netherlands to interview the community manager for Shapeways, [Bart Veldhuizen].

Unlike the RepRaps, Ultimkers, and Makerbots, Shapeways is an entirely different ecosystem of 3D printing. Instead of building a machine that requires many hours of tinkering, you can just upload a model and have a physical representation delivered to your door in a week. You can also upload objects for others to buy. Despite these competing philosophies, [Bart] doesn’t see Shapeways as encroaching on the homebrew 3D printers out there; they serve different markets, and competition is always good.

Unfortunately, [Andrew] wasn’t allowed to film on the Shapeways factory floor. Proprietary stuff and whatnot, as well as a few certain ‘key words’ that will speed your customer support request up to the top of the queue.

As for how Shapeways actually produces hundreds of objects a day, [Andrew] learned that individual orders are made in batches, with several customer’s parts made in a single run. While most of the parts made by Shapeways are manufactured in-house, they do outsource silver casting after making the preliminary positive mold.

As for the future, a lot of customers are asking about mixed media, with plastic/nylon combined with metal being at the top of the list. It’s difficult to say what the future of 3D printing will be, but [Bart] makes an allusion to cell phones from 10 years ago. In 2003, nobody had smartphones, and now we have an always-on wireless Internet connection in our pockets. Given the same rate of technological progress, we can’t wait to see what 3D printing will be like in 10 years, either.

Homebuilt Laser Cutter Ideas

Laser-Cutter

[Wuzabear] wrote in to tell us about this “DIY Laser Cutter for PCB Stencils.” While a full BOM and step-by-step build instructions aren’t provided for the frame, pictures of the build are available, and some different options for construction are discussed. One other option that was especially interesting would be to use a ready-built RepRap or other 3D printer to act as the laser motion controller. Apparently this has been experimented with, and we’d love to see any versions that or readers have come up with!

Besides some different ideas and resources for the moving parts of the cutter, there is some information on how to hook up a laser for this purpose, as well as  for the software and calibration required. It should be noted that you should always wear the appropriate safety goggles if you’re working with a high-powered laser. Although any machine-tool can be dangerous, lasers provide some safety issues that should be treated with extreme caution.

Interview: Another Kickstarter Round For The B9Creator

March 30, 2013 by 27 Comments

The Dawn of the 3D Printing Age - Art by Dennis HarrounNearly a year ago, the 3D printing scene saw a few new printers based on a technology other than squirting plastic out of a nozzle. These printers used DLP projectors underneath a vat of UV curing resin to build objects one layer at a time with incredible resolution.

Probably the most successful of these printers is the B9Creator from [Michael Joyce]. His original Kickstarter took in half a million dollars – 10 times his original goal – and still managed to deliver all the kits to backers within 2 weeks of the promised date. Now, [Michael] is running another Kickstarter before taking his printers to select distributors. We played some email tag with [Michael] for an interview discussing the perils of a hugely successful Kickstarter, and the future of the B9Creator ecosystem.

Check out our interview after the break.

SCARA Arm Finally Prints Plastic Parts

February 25, 2013 by 24 Comments

SCARA

Here’s a neat alternative to the usual gantry setup you see on 3D printers. [Quentin] designed and build a SCARA arm 3D printer that just saw its first print.

We caught wind of [Quentin]’s SCARA arm a few weeks ago when it was still just a few plastic parts and a glimmer of ambition in its creator’s eye. Most of the parts are 3D printed, including the blue arms for the x and y axes that are driven by stepper motors. The z axis is controlled by two lead screws, and judging by the height of [Quentin]’s machine, he has a pretty big printable volume – at least as large as some of the delta bot 3D printers we’ve seen.

So far [Quentin] has printed a handful of calibration cubes and a wheel with a fairly impressive print resolution. You can check out a video of the SCARA arm printer after the break.

[Prusa]’s Nozzle Prints Polycarbonate, PEEK, & Nylon

November 27, 2012 by 42 Comments

Oh, we’ve been sitting on this one for a while.

[Josef Prusa], brainchild behind what is probably the most popular 3D printer, has just unleashed a new hot end that is capable of printing objects in polycarbonate, PEEK, and nylon.

This new hot end is completely made out of stainless steel – there are no plastic parts made out PTFE or PEEK to keep the heat from transferring up to the extruder. Because the Prusa Nozzle can print these plastics, it’s also now possible to print parts for other hot ends such as the J Head and the Budaschnozzle.

We ran into [Prusa] at NYC Maker Faire a few months ago, and he was kind enough to go over the advancements in his new nozzle and new i3 printer. So far, it looks like the lack of a PEEK insulator isn’t doing the new hot end any harm – [Prusa] has left molten plastic in the nozzle for a few hours and nothing bad has come of it.

You can check out the interview below.

Again, thanks to [Prusa] for granting us an interview and providing some free advertising for Hackaday’s hosts for the NYC Maker Faire. Before you complain about the delay in getting this interview out to you, don’t worry; I slapped a few Makerbot stickers on the back of [Prusa]’s jacket. Everything’s cool.
