Cytosurge Improve their FluidFM µ3Dprinter with Pinpoint Accuracy Tech

I wrote about Cytosurge technology before. They developed a 3D printer that can print metal on the micro-scale. A true technological wonder. Just imagine small robots floating in your bloodstream to repair your body or extremely complex and fine electronic parts like micro-antenna arrays. Star Trek stuff. This is a technology that makes a large step towards that future. 
The company has now improved their machine with ability to print directly and precisely on complex surfaces like existing electronic component boards or microchips. 































Tech description:

The new pinpoint metal additive manufacturing process is made possible by two high resolution state-of-the-art cameras integrated into the FluidFM µ3Dprinter. The cameras enable automated loading of the print tips (FluidFM iontips), printer setup, calibration and computer-assisted alignment to print on already existing structures as well as the visualization of the finished structures. The bottom view camera is mainly used for internal system processes, like controlling the automated gripping of the FluidFM iontip. The top view camera images the object or surface to print on. With the high-resolution live video, the exact position of the object or surface to be printed on can be manually chosen and set as starting point for the printing process.
This procedure allows the user to print metallic objects on contact pads that are pre-defined on the surface of an integrated circuit, on micro-electromechanical-systems (MEMS) or on other components.
This unique capability of the FluidFM μ3Dprinter to add 3D printed structures directly onto existing objects or surfaces with pinpoint accuracy opens the door to a new world of additive manufacturing of complex metal objects.

3D Printed DIY Arrowheads by Juleah

Making your own archery equipment is one of the essential skills any archer should master. Here is a cool and useful DIY project made by Juleah, where she used a 3d printer to make printable arrowheads or field points.


Here you can see two videos detailing the entire target testing and improvement process:





The final version of horizontally printed points is strong enough to go through soft hay targets.








You can find out more about Juleah and her work at:

Decentralize your DIY projects with LBRY

If you consider yourself a part of DIY or 3D printing community, you most certainly regularly look at other peoples projects or publish your own work on some platform like YouTube, Thingiverse or Instructables. There is an incredible amount of knowledge and value being contributed by users every day - but do they get the fair amount of value back from those platforms?

Since all of the biggest platforms are privately owned, what would happen if those companies decided to close them for any reason destroying all the content in the process? Or decided to charge you a fee for publishing your content or decided to remove your content for some arbitrary reason ... or got hacked ... there are many very negative outcome scenarios since there is too much power accumulated within a single point of failure. Currently, many YouTube creators in DIY space are faced with random demonetization and there have been major problems with Thingiverse in the past.

Is there an alternative? Looks like there is! It is a decentralized, open-sourced blockchain based system named LBRY (Library). With LBRY there is no middleman.

LBRY is best described as a content platform (YouTube or Thingiverse) that works similar to a BitTorrent network where each user downloads and re-publishes the content he viewed.


You can read the full description here:

https://lbry.io/faq/what-is-lbry


Or watch this short description video:



LBRY is currently a great platform for video creators who want to increase their reach, secure their presence, improve monetization and are not satisfied with YouTube policies and uncertainty due to demonetization or censorship. If you are an existing YT creator, there is a simple YT import procedure you can find here:

https://lbry.io/youtube


The application interface is simple and easy to use, here is a short overview by Wayne Beach:




In the future, there will also be a mobile app available.


LBRY is not only for video, you can also publish all your project files, code or any other digital format on the Library app. LBRY is open sourced, so it can be used in a variety of roles as a specialized platform. One current implementation is spee.ch website which "takes" the content from the LBRY chain and acts as a decentralized image hosting site. Any developer could use the technology and develop a web browser accessible Thingiverse alternative for 3d printing files.

Publishing .STL files is very easy, just click on the green "Publish" icon in top right corner:





Your content can be monetized with LBRY credits cryptocurrency or you can receive tips for your work. LBRY crypto can be exchanged on many exchanges for Bitcoin or the regular money.

Do keep in mind that LBRY is still under development with a constant stream of new improvements and features being added. I know that most of you are more than capable of using this type of software and even give some feedback to the developers to make it even better.

Now go and give LBRY a test run to distribute that great content you made!!! Sharing is caring!

3D Printed Military Submersible

Engineers in ORNL made military’s first 3D-printed 30 feet long submersible hull made from carbon fiber composite material.
The Optionally Manned Technology Demonstrator is a prototype vessel that could be used to deploy divers, logistics capabilities, and sensors. It was made much cheaper and faster when compared with traditional manufacturing methods.

We don't need more weapons guys. We need more technology for permanent peace.
