Thermaltake 3D Printed Modding Accessories

As 3d printing is going mainstream, many companies see the potential using it as user involvement tool. Thermaltake, PC parts manufacturer, started their 3d printing site to help PC modders 3d print components for their cases, fans, LED lightning, drives and other peripherals.

Here are some fan grills:

nUnitled 3D Printer and Giova's Extruder from Italy

nUnitled 3d printer and Giova's extruder are DIY  machines developed in 2015 from Italy which are low cost and feature some interesting solutions.
The main feature of this project is its anti-wobble system which consists in the separation of Y and Z axis from Z screws. Y axis can moves freely on Z axis, because it's leaning on Z screws. This innovation avoids the transmission of Z screws wobble to Z axis.
This machines has wooden support structures.
Giova's extruder aims to be light and low-cost extruder based on the cheap 28BYJ-48 motor. It is relatively weak but it works.
Third party reviews are not yet available.

Here is the presentation video:

3D Printing Custom Car Audio Speakers

As I was searching to find what can I print for my car, I found Mark and his company. It is an excellent example how 3d printing can help a small company to make custom products. They use 3d printing to make custom car audio speaker boxes, pods and attachments that look vary cool.
They may run out of business when 3d printing spreads and Maker / DIY culture becomes mainstream ;-) Probably not, as they certainly have creative spirit which will enable them to thrive on the market.

When someone re-invents the wheel with some 3D printing help

OK, it's a skateboard wheel, but it is designed as a strange combination o cube and sphere and other stuff ... they were 3d printed and polyurethane casted 
I'm not even sure how they work and I never rode a skateboard in my life :-) but they look cool!




From video description:
A fascinating interview with David Patrick from Shark Wheels. David explains how the latest techniques in Rapid Prototyping helped him in the process of developing his unique product; Shark Wheels.
It's a wheel that comes from a cube: the Shark Wheel shape is a perfect cube and a perfect circle and a perfect sine wave!
The Shark Wheel geometry is the intersection of a cube, a sphere, and a three-dimensional sine wave. It is based on the shape of shark jaws and is a pattern found all throughout nature. David M. Patrick discovered the shape while studying natural sciences, and has since been developing the Shark Wheel to be a more efficient wheel with superior performance in many ways. David's passion for skateboarding coupled with his interest of the natural world have led to the discovery of the Shark Wheel.

"Super Make Something" Tutorial On How To Build a Simple 3D Scanner

This youtube channel gives a step-by-step tutorial on how to make a simple 3d scanner with 3d printed parts and IR sensors. It outputs the scan data on a SD card which you can then turn into 3d model using MATLAB. The results are somewhat rough and you will need one custom electronic board but it is a nice learning projects.

Here is the tutorial video:

CRACUNS flying and diving 3D printed drone

Johns Hopkins University developed 3d printed quadcopter drone that can both fly and be submerged under water. Since it was developed in cooperation with the military it will be probably be used as a weapon system sometime in the future. Cool technology, but we need more food delivery drones and less war-bots. It is named CRACUNS, which stands for "Corrosion Resistant Aerial Covert Unmanned Nautical System".




From the news article:
“Engineers at APL have long worked on both Navy submarine systems and autonomous UAVs,” said Jason Stipes of APL’s Sea Control Mission Area, project manager for CRACUNS. “In response to evolving sponsor challenges, we were inspired to develop a vehicle that could operate both underwater and in the air.” The resulting CRACUNS prototype system was developed and tested using internal research and development funding.

CRACUNS enables new capabilities not possible with existing UAV or UUV platforms. Its ability to operate in the harsh littoral (shore) environment, as well as its payload flexibility, enables a wide array of potential missions.
The most innovative feature of CRACUNS is that it can remain at and launch from a significant depth without needing structural metal parts or machined surfaces.To make that possible, the team needed to overcome two big challenges. First, the APL team leveraged advances in additive manufacturing and novel fabrication techniques available at the Laboratory’s extensive fabrication facilities. The team fabricated a lightweight, submersible, composite airframe able to withstand the water pressure experienced while submerged.
The second significant challenge was to ensure CRACUNS could not just survive, but operate effectively in a corrosive saltwater environment. To do that, the APL team sealed the most sensitive components in a dry pressure vessel. For the motors that are exposed to salt water, APL applied commercially available protective coatings. The team tested the performance of the motors by submerging them in salt water. Two months later, they showed no sign of corrosion and continued to operate while submerged.

Hydraulic 3D Printed Insectoid Robot

Researchers at MIT CSAIL developed a 3d printing process named "printable hydraulics" where you can 3d print with soft and hard materials at the same time. This creates articulated objects which can move when pressure is applied.
They demonstrated it by 3d printing an insectoid robot that moves when motor and battery is added. Other robotic accessories such as hydraulic grippers can also be 3d printed.

Hydraulic hexapod in action with other flexible parts demonstrated:

How to build an Ultimaker2Go low cost clone

PaulSS made a build log on Instructables about his Ultimaker2 Go DIY clone. It is much cheaper then the 1600 USD original at some 500 - 600 USD. The frame is made on a CNC from plywood.
The machine is named Ultifaker2Go :-)
