Low Cost DIY UV Curing Chamber

kidNeutrino shared this great solution to UV curing of resin 3d printed parts. It's a low cost DIY solution that can be made for some 30 USD and consists of aluminum foil covered cardboard box and a gel nail dryer lamp.
You just put your part in, turn on the dryer UV lamp and let it cure.

Jonathan Odom's 3D Printable Wireless Lantern Based on Qi Inductive Power Technology

Jonathan Odom developed and shared his great looking DIY 3d printable LED lamp. This battery powered wireless charging lantern will glow for 1.5 hours on a single charge. It works with a few cheap electronic parts and a USB charger. The USB cable plugs into the base, and the lamp sits on the base and charges through induction via Qi Universal transmitter and receiver.
The lamp housing, charging base, and lens are all 3D printed on a almost any standard FDM printer since the lamp is a 5" X 5" (127mm X 127mm) cube.

NVPro 3D Printer with Automatic Parts Removal

New Valence Robotics teases their new 3D printer: the NVPro. Interesting feature is the integrated automatic parts removal.
It ejects the part from the build plate, so you can keep continuously printing new things. We will see it in realistic operating conditions hopefully...

Here is the product teaser:

Single Actuator Wave-like 3D Printed Robot

SAW is a 3d printed robot that can crawl, swim and climb using wave motions with only one motor. And it looks creepy.

From project description:
SAW (single actuator wave-like robot) is the first robot that produces a pure wave-like motion with a single motor. The robot was developed for medical, industrial and search and rescue purposes. The design is simple, 3D printed and the passive wheels are for steering only. In the movie we show that the robot can crawl over different surfaces, climb and swim. It reached a maximum speed of 57 cm/s which is 5 times faster than any other similar robot.
The robot's design is simply and highly reliable very little maintenance was needed.
The robot's motion is similar to the "do the worm" dance.
The robot was developed at the Bioinspired and medical Robotics lab at BGU by David Zarrouk, Moshe Mann, Nir Dgani, Ilanit Waxman, Tal Yehuda, Nissan Jerbi and Amotz Hess.

Laser-assisted Advanced 3D Printing with Silver Ink

Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering and the John A. Paulson School of Engineering and Applied Sciences (SEAS) developed a new 3D printing method.

They use a miniature nozzle to spray silver ink that is solidified by lasers in midair to produce self-supporting 3D structures.

The application of this technology will probably be in advanced electronics circuits production or biomedical devices.




























Here is the video of the process:

Here is a great video that explains everything you wanted to know about stepper motors but were afraid to ask :-)



Great work GreatScott! Thanks for the content!

Easy WiFi 3D Printer sharing with Microsoft IoT Core

I'm not a Microsoft fan but it looks like their IoT Core on a Raspberry Pi can get easy WiFi connectivity and network sharing for many popular 3D printers with simple app install.

Here is the video explaining the setup:




It currently supports the following printers:
  • Lulzbot Taz 6
  • Makergear M2
  • Printrbot Play, Plus and Simple
  • Prusa i3 and i3 Mk2
  • Ultimaker Original and Original+
  • Ultimaker 2 and 2+
  • Ultimaker 2 Extended and Extended+
... but more will surely be added in the future ...

Thor Open Source Robotic Arm from Spain

Thor is an Open Source and 3D printable robotic arm with six degrees of freedom developed by Ángel Larrañaga Muro from Madrid, Spain.

Its configuration (yaw-roll-roll-yaw-roll-yaw) is the same one that is used on most manipulator robots that currently exist in the market. In its upright position, Thor is about 625mm and it can lift objects up to 750 grams.

Here is the video showing Thor in action:




Here is the CAD animation of the assembly process:

BCN3D Moveo Open Source 3D Printed Robotic Arm

BCN3D presents Moveo, a fully 3d printable open source robotic arm. Another step toward fully robotic world where we puny humans will be free of any work :-)




From project description:

BCN3D Technologies keeps taking important steps in order to achieve his goal of bringing the digital manufacturing technology to everyone. In this occasion we are presenting the BCN3D Moveo, a robotic arm design from scratch and developed by our engineers in collaboration with the Departament d’Ensenyament from the Generalitat de Catalunya.
Its structure is fully printed using additive manufacturing technologies and its electronics are controlled by the software Arduino. The BCN3D Moveo has 5 axis.
Moveo, fully functional nowadays, has been born, as all the BCN3D Technologies products, with an open and educational wish.
As we have done with all our developed pordutcs, the BCN3D Moveo files will be available for everyone. Thanks to the platform Github, a website where users around the world share their designs, anyone will be able to obtain all the necessary information in order to assemble his own BCN3D Moveo at home.
Nevertheless, BCN3D will fee all the Moveo know how on our Github account, as we have been doing with all the BCN3D Technologies products. Thus, the users will be able to find the bill of material (BOM), where all the needed components for the assembling of the arm come detailed, as the CAD designs, so anyone will be able to modify the BCN3D Moveo design as they wish.
Furthermore, the Github users will find the STL files for the structure printing and the assembling, fine tuning and firmware upload manuals, which will be available both in English and Spanish.

Download the BCN3D Moveo CAD files, the STL files, the assembly and user manual and the Bill of Materials on our Github: https://github.com/BCN3D
