DIY Silicone Nozzle Cover

One way to protect your nozzle from getting dirty is to wrap it in a cover, sock, sleeve or boot and prevent all the hot nasty stuff sticking to it. E3D released their silicone sock for Vulcano nozzles but someone found a way to make a DIY version.

Ubermeisters used 3d printed model of the nozzle and made a mold around it and than used some high temperature silicone mixture to produce the final cover. All steps are photographed in detail.

Here are the files and the instructions:

What if you could carry a small 3d printer everywhere?

What if you could carry your 3d printer with you as a small bag? What if 3d printers were everywhere? Researchers at HPI explored this possibility with actual hacked 3d printers and 3d printing pens to  test the implications on everyday life.
It would basically give you magic power to repair and replace everything on the spot with incredibly low cost. Sure, we are not there yet, but technologies and concepts are slowly converging to this point.

Here is a detailed talk by Thijs Roumen about the entire concept, the research conducted and the results:

Here is a video focused on the mobile printing process:

They used modified M3D machine which was cut down to more compact size of 9cm in hignt, equipped with a UDOO control PC computer, shoulder strap and a battery. I expect that someone will make simillar open sourced machine soon.

3D Printing History 6 - Small Soldiers

Here is probably one the first appearance of a 3d printer in mainstream cinematography. It was in a movie named "Small Soldiers" from 1998. My kid brother really liked that one.

They show an early stereolitography machine, the model looks realistic when it comes out of the resin tank, but the process was made to look faster and with visible lasers.

Here is the video from YT:

MIT Foundry software is amazing, but will it be available to public?

MIT CSAIL scientists developed Foundry CAD / CAM software which they call "Photoshop for 3d printing". It looks amazing with many advanced options.

The main question will be open sourced and available for wider 3d printing community? I strongly support that all software developed by public funding be released under an open source license.
One of the articles claim that the developer, Kiril Vidimče, wants to integrate it  into the workflow of existing CAD systems. We will see ...

Here is a video of Foundry in action:

Switcher DIY Power Modules For Smart Home Projects

Hristo Borisov developed and published a set of 3D printable socket and switch modules that are controlled by ESP8266.
ESP8266 is very interesting piece of electronics since it is very small, affordable (some 4 USD) and powerful since it has WiFi and can be used as Arduino.
With this project you can control your electric devices via WiFi remotely and setup a simple DIY smart home project for a fraction of a price of commercial proprietary solutions.

Sockets are fully 3D printable and are of standard European "Schuko" type, designed in Autodesk Fusion 360. Design is modular so you could probably easily change it to any other socket standard.

There is even an iOS app for remote control of modules. Project is also open source so they get extra pints in my book.

Project homepage with all the code and instructions:

GitHub repository with all the code and STLs:

Stay safe when working with home electric power systems :-)


looks like there is a simillar commercial system that is also very affordable, but it is not open sourced:

It may be possible to flash it with custom firmware but it doesn't have a socket but the wires should be connected to it.
