BadDevices for 3DRacers

BadDevices participated with 3DRacers (http://www.3dracers.com/) to promote their Indiegogo campaign! with a video of one of the 3D car model, the Blu Corvette, printed with our BadPrinter2.

Check out their awesome project on indiegogo page where Marco and the 3DRacers team are collecting the funds to create small and fun RC car racing that everyone can print and customize.

We participate also in an Italian TV show “I fatti vostri” to live promote the project.
You can see the show clip here, from minute 6.00

Soluble support with PVA and BadPrinter2

We tested the PVA material (Polyvinyl alcohol) to create the support for PLA sample object with strong overhangs (an helical object) that normally is in impossible to print.
We want to prove the multimaterial capability of the BadPrinter2.
We used Cura as slicer with our script for double colour that, during the tool change, moves the hotend to a “parking” area and cooldown the unused one to reduce as much as possible the oozing during the next print phase.
The PVA is a very flexi material, so the retraction has to be used with attention; as you can see in the photo, there are a lot of “strings” of material generated during the material change, but the PVA is water soluble and they can be easily removed in the post-processing without impact on the quality of the PLA part.

In the following video you can see the post-processing operation of removing the PVA support by submerging it into cold water. We know that leaving the part in warm water for about 24 hours cause a complete dissolving of the PVA, but we want to show that also after about 30 minutes in cold water the material became slippery enough to remove easily the support at the interface between PVA and PLA.

What’s new in the second batch of BadPrinter2

We completed the first six BadPrinter2 of the second batch.
All the machines are completely designed, assembled and tested by us, so our production rate is quite small; this is the reason why we are proud when we see those machines standing in line, ready for shipment. Half of them are headed to Germany; we are happy to start spreading also some BadPrinter2 across Europe.

Two big improvements were included in this new batch; a completely redesigned heated bed and the new E3D v6 hotends.
There are some other minor changes included in the design to improve the reliability and usability of our printer.

Heated Bed: The “old” Alu sheet had done its work, but it was, sometime, tricky to adjust; also the tempered glass was not completely planar due to the heat treatment.
We switch to an 8 mm milled aluminum plate with side thrust pin on both sides in order to retain firmly the glass, but allowing a quick removal of it.
The square glass is replaced by a not tempered one (more planar) with 5 mm thickness with the option to have also a more stylish smoky glass.

v6 hotends: in the same way, the v5 hotends are very good quality extruders, but the new one are more compact, clean (no messy kapton on the hot part to retain the thermistor in place) and with the bowden tube that goes all through the cold part there is an improvement when printing elastic and soft filament.
For the same reason, also the filament feeder bowden coupling was replaced by the bigger plastic one that allows the bowden tube to goes closer to the feeder gear.

Big update on BadPrinter2 production

It’s been a while from the last update on our blog.
The last post reports our partecipation to the MakerFaireRome 2014 and it’s dated two months ago (the time is running very fast :-))
A brief description of our esperience there: we met a lot of nice people and lot of curious persons.
We are happy to show the series version of our BadPrinter2: the people were impressed by the quality of the printed objects, and also by the quality and construction of the machine and we are very proud of that.
A lot of work going into the design and we want our machine to be a robust and reliable 3D printer and we think we had succeeded in the task.

Coming back from the faire we had a lot of things to organize, we want to start with the second batch of machines and we had to plan a lot of things: some minor upgrade in the design and the production. We have to buy and manufacture all the part needed and to print a lot of plastic parts. Our new milestone is to go for twenty machines.
We are not alone in working on the production; our trustworthy BadPrinter2 are helping us by printing late at night to produce all the parts of their “sister” machines. We had a total of about 1800 parts to be printed for all the twenty machines 🙂

We hope to be able to run the new website soon, we are defining the latest details; for the moment keep in touch with our “classic” blog 🙂

Football CUP

After scripting a good printer configuration for dualcolor printing we thought that a football ball would have been a good example to test our solution, there are ever 2 colors in each layer and 15cm diameter is not so tiny
During the printing of the ball we thought that we would have needed something to hold the ball… and so the football cup idea 🙂

Next step: double material 🙂 Stay tuned ^^

Summertime Printing

It’s summer, but BadDevices never goes to holiday; we are trying to obtain the best from our BadPrinters by printing some big and nice object and we are also concentrating in tweaking the correct parameters for dual printing.

Here some of our latest pieces

And some work in progress, like the awesome multi-part GE jet engine (the main fan is missing in the picture) and some “mistery” object 🙂
