Angus And His Experiance With 3D Printed Combat Robot Parts

Angus from Maker's Muse shares his knowledge and experience with a DIY battle robot he created. Since it uses a lot of 3d printed parts it is interesting to see how they cope in this type of application. The robot is named "Vanguard", and it's a 30lb of pure machine aggression :-)

Don't try this at home!

Here is a somewhat crazy and unsafe project from RCLifeOn YT channel. It is butane gas fueled hand mounted DIY flamethrower.

You may find it interesting but I think it is very dangerous to have the fire so close to the flammable glove made from plastic.

I would not recommend anyone trying this. Stay safe people!

Simple DIY 3D Printable Bluetooth Speaker

Here is a simple and easy 3d printable battery-powered Bluetooth speaker you can make with even basic electronics skills. It was developed and published by Hardiq Verma.

HRL 3D Printing High-strength Aluminum

HRL made a major breakthrough in metal additive manufacturing by developing a process enabling 3d printing of non-weldable metals like aluminum. This will certainly play a big role in future manufacturing facilities and product development.

Project description:
MALIBU, Calif. Sept 20, 2017 — HRL Laboratories, LLC, has made a breakthrough in metallurgy, developing a technique for successfully 3D printing high-strength aluminum alloys — including types Al7075 and Al6061 — that opens the door to additive manufacturing of engineering-relevant alloys.
HRL's nanoparticle functionalization technique solves this problem by decorating high-strength unweldable alloy powders with specially selected nanoparticles. The nanoparticle-functionalized powder is fed into a 3D printer, which layers the powder and laser-fuses each layer to construct a three-dimensional object.  During melting and solidification, the nanoparticles act as nucleation sites for the desired alloy microstructure, preventing hot cracking and allowing for retention of full alloy strength in the manufactured part.
Because melting and solidification in additive manufacturing is analogous to welding, HRL's nanoparticle functionalization can also be used to make unweldable alloys weldable

3 Simple Hacks to Protect your Files from Theft, Piracy, and Plagiarism

Angus from Maker's Muse shows how he protects his files from theft, piracy, and plagiarism. He uses watermarks, invisible or hidden watermarks, and hiding a text into a file. All those measures can be defeated but that is just nature of the digital world.

3D Printable DIY Moka Pot Made with Formfutura Volcano PLA

Stefan from CNCKitchen in Germany designed and successfully made a fully functional 3d printed coffee Moka pot. Due to high temperature needed to reach the internal water pressure he used Formfutura Volcano PLA. Do keep in mind that this is a demonstration and not everyday usage object. The pressure build-up in a closed plastic vessel can be dangerous.

DIY Open Source 3D Printable Submersible Glider Drone

Alex Williams developed and built this sophisticated open source submersible glider drone. 3D printed elements are the main components.

Project description:

There has been a breakthrough with low cost autonomous drones and as this capability has matured a wide range of hobby and commercial applications have developed. There are no affordable extended duration underwater exploration platforms and this project aims to address this need. 
Utilising commodity hardware, 3D printed parts and an open-source autopilot, I aim to produce a low cost and versatile underwater glider capable of extended missions of up to weeks at a time. I hope that by having this platform available, it would reduce the cost of underwater projects for all, from hobbyists, amateur scientists to seafood farmers

Vitaprint 3D Bioprinter by IRNAS from Slovenia

IRNAS Institute from Slovenia is developing some serious bioprinting open source machines. Respect.

Project description:
VITAPRINT is an open source 3D bioprinting project developed by our Symbiolab. It is a platform of open 3D bioprinting, including open hardware, methods and demo files, which serves as a basis for our collaborations with researchers from science and industry. We act as the key technology partner and help them apply the convenience of 3D biofabrication technology in their specific application and facilitate the transition of ideas into operational devices and procedures.
