First look at Cloud Based Fusion 360

Many of you use Fusion 360 as main design application. Adafruit team shows us the first view at browser based Fusion 360 system. Personally, I'm more fan of the open source software and I don't like to depend on a big corporation.

SAM Robotic Brick Layer

We have seen extrusion based construction 3D printers that build with cement paste layers. SAM is a robotic bricklayer that uses standard masonry bricks. It can also be considered as a type of 3D printer since it is using additive manufacturing guided by a computer.
Despite some light statements in the video, a construction worker is probably not a job position with bright future.
Sure, SAM needs human assistance now, but it is highly likely it will be fully autonomous in the future. The two workers that assist it now probably displace ten workers because of the efficiency.

Video description:
Meet the Semi-Automated Mason or SAM, a robot that is so good at building walls it could take over the construction industry. Created by New York-based company Construction Robotics, the brick-laying robot promises to both increase productivity while reducing overall labor costs.
While the efficiency on construction sites has been stagnant in the last 20 to 30 years, manufacturing efficiency has increased significantly due to robotics and technology. Construction Robotics created SAM to solve that problem. SAM requires a human partner to smooth over the works, but the heavy lifting is left to the bot.
The robot can lay bricks at least three times faster than humans – and it never gets tired or makes mistakes. VICE News went to a construction site in Virginia to see SAM at work.



DIY Bench Clamp Made On a 3D Printer

Chuck designed and made this very useful bench clamp on his 3d printer. It uses some M6 metal bolts and nuts but it can easily be converted to other sizes.

It goes through a hole in a workbench and holds objects safely in place so you can work on them.

3D Printing Parts for Cryptocurrency Mining Rig

Cryptocurrency mining is booming again with Ethereum currently being one of the most mined coins. In many countries graphics cards (GPUs) used for the process are hard to find or are much more expensive. For mining purposes, several cards are mounted on a single motherboard with a riser connector and attached to an open external rig for more space to get better cooling air flow.
Most mining rigs are self-built by the operators who always want to get the best price to quality ratio.

Here are a few very practical 3D printable DIY modules you can make yourself and use in your setup.

Here is a somewhat typical mining rig but all the connections of metal profiles and structural elements (red and black plastic) were 3d printed:

If you don't want to keep your GPUs on a riser connected to a rigid frame to get more space or flexible arrangements for better cooling, you can use DIY 3d printed card holders.

Using 3d printing to build your hashing beast is a great way to ensure spare and replacement parts and it gives you much more customization options. You can also get various type of fan holders, air flow focusers, PC component holders, and many other components.

3D Printable Mortise and Tenon Jig for your Dremel

If you need a cheap DIY jig for mortise and tenon making for your woodworking projects here is a simple 3d printable version that uses a Dremel tool for cutting out the wood.
It was developed by Crafted3D since he needed a cheaper alternative for a 1000USD standard router.

There are a few non-printable parts like a metal clamp, but this is a great low-cost shop tool. You could also design different templates for the shape of your tenon/mortise parts.

3D Printed Boat Propeller by Jaimie Mantzel

Jaimie Mantzel is living on an island in Panama and he is building his own little paradise with his family. He has a lot of interesting projects from solar boat making to dome house building. He documents most of his life on YouTube, his channel is well worth following.

He uses DIY solar powered boats and he makes self-made 3d printed propellers for them.

Modular props with replaceable modules:

Here is the real test:

Big Benchy RC Boat

You like making the 3DBenchy? Now you will like it even more with this project! Kim developed a larger version that can float and has an RC control for a small electric motor. It is 3d printed from several modules and held together with ABS-juice which also makes it watertight.

Very Loud DIY Filament Alarm

Donald Papp developed a simple but loud alarm, "Mister Screamer", that is hanging from your filament and if the filament runs out it triggers a loud alarm.

Key features:

  • If filament is present, nothing happens.
  • If filament runs out, scream your fool head off to alert a nearby operator.
  • Enclosure can be 3D printed
  • Self-contained (no external power or signals)
  • Requires no modifications to the 3D printer to be monitored
  • Electrically simple, and using a minimum of easy to source parts
  • Long battery life, low power usage
  • Easy to turn off when responding to an alarm

3D Printed Molds for Concrete Frame Canoe

Project description:
A research team from ETH Zurich used 3D-printed moulds to make the skeletal framework for this all-concrete boat, which won first prize for design innovation at the Concrete Canoe Regatta.
The boat race takes place every other year on the Rhine river in Cologne, Germany. It challenges participants to create the lightest and fastest vessel, and race it 200 metres without sinking. The competition allows no other material than concrete to be used.
For their SkelETHon canoe, the team from ETH Zurich relied on research that allowed them to fabricate large-scale concrete building components, casting concrete in any shape using 3D-printed moulds.
"With 3D printing we have an almost unlimited geometrical freedom for making formworks, which was not available to concrete so far," said the team's Andrei Jipa. "Undercuts, microstructures, high-resolution details are now possible."
The moulds are made from recyclable plastic, and allowed the team to cast slender "bones" – some of which measured just 15 millimetres in diameter – from steel fibre-reinforced concrete.

ZeroBot is a 3D printable FPV robot based on Raspberry Pi Zero

ZeroBot is a cool little 3d printable robot that is cheap and easy to make. Great for educational robotic projects. You can control it via the smartphone interface and all the software is available as SD card image. I'm making this!!!

Project description:
ZeroBot is a Raspberry Pi Zero W based robot. It can be controlled using any computer or smartphone via a web browser. The integrated camera module makes for a low latency video stream. In addition, the Raspberry Pi acts as a Wifi access point, so no router is required. The parts for the hull as well as the wheels can easily be printed on any regular 3D printer. 
Some of the key features are:
  • Compact CAD design with 3D printed components
  • Analog control via a joystick (and multitouch)
  • Simple battery solution using only a standard power bank
  • Low latency streaming (~0.3s)
  • Easy and cheap to build using widely available components

3D Printed Small Internal Combustion Engine from Romania

Researchers from Romania 3d printed a small working two-stroke engine on a professional metal 3d printer.

Project description:
Romanian Valentin Stamate, a researcher at the Transilvania University in Brasov, presented a 3D printed two-stroke airplane engine prototype. It cost some EUR 20,000 to manufacture and the expense was undertaken by the Brasov University.
The engine is a 10 cubic centimeters one, with 10,000 rotations per minute. Most of the engine parts were produced by SLM and SLS-type 3D printers out of steel, aluminum, and steel and bronze powders. The only parts that were not 3D printed were the propeller, which is made of wood, the cone and its fastening system, the supporting bearings, the screws, the nuts and the spark. The engine is fueled by a mix of methanol and oil.

Now, I know what you are thinking: interesting project but 20 thousand euro is a lot of money for a small engine. Any you are right.
The first thing that came to my mind was my lawn mover broke a few days ago, and since I live in Croatia the replacement part was hard to find and too expensive for my taste. There are MANY small engines in the world and with right investment and economics of scale, this is a very large market. Just the replacement part market is huge with thousands of different engine models with hundreds of parts each.

Now go and make it happen.
