Apis Cor 3D Prints a Fully Livable House

We have seen 3d printed buildings before but most of them were prototypes, built off-site or not used afterwords, but nothing compares to this house built by Apis Cor.

Apis Cor used a unique house 3d printing machine they developed and made an on-site house in 24 hours for the cost of some 10000 USD. It has surface of 38 square meters (409 square foot) and has been built in Stupino town, Moscow region, Russia.
The finished house is fully livable with all the appliances. Very cool!

Here is the very interesting presentation video:

Looks like 3d printing houses is a technology that has fully matured now. It will have interesting effects on housing market.

New Cura 2.4 released with tons of new features!

New Cura 2.4 is released by Ultimaker. It has many new features and improvements. Here are just some key novelties:

  • Project saving / opening. Cura 2.4 now lets you save your build plate configuration, which includes all your active machine’s meshes and settings too. Even more conveniently, when you reopen your project file, you’ll see that all build plate configurations and settings are exactly as you left them when you last saved the project.
  • Search Settings. Need to tweak a setting in a hurry? It’s now easy to search custom settings via the side panel.
  • Editing start / end g-code. If you need to alter the start and end g-code settings for your single-extrusion machines, the new Cura 2.4 lets you do just that.
  • Multiply object function. We know that duplicating an object multiple times can be a hassle, so we’ve made life easier for you. Simply right-click an object, and you can multiply it by a variable amount.
  • Single-extrusion prints. Your Ultimaker 3 dual-extrusion printer now lets you do single-extrusion prints within a larger printable area.
  • Streaming printer monitor view. Selected camera snapshots don’t really tell you much about how your print project is progressing. Now, you’ll be able to follow every second of your 3D print (if you want to), using the live streaming function. It’s an effective way to minimize errors while printing.
  • Slicing disabled? Now you’ll know why. It’s a bit frustrating when your slicing is blocked by settings with error values, but you don’t know which settings to change to make things right again. Now, a message will appear, clearly outlining what needs to be done to get your print back on track.
  • Ultimaker 3 printing profiles. The initial and final printing temperatures reduce oozing during PLA/PLA, PLA/PVA and Nylon/PVA prints. This means printing a prime tower is now optional (except for CPE and ABS, which we’re working on). The new Ultimaker 3 printing profiles boost reliability and reduce print time.
  • Initial layer printing temperature. We’ve fine-tuned the initial and final printing temperatures, to achieve a higher quality end-result.
  • Material printing temperature. The material printing temperature (in the material profiles) is now the same as the printing temperature for the Normal Quality profile.
  • Improved PLA/PVA layer adhesion. It’s important to get good layer adhesion between the PVA and PLA. That’s why we’ve now optimized the PVA jerk and acceleration.
  • Nylon – default build plate adhesion type. We’ve now changed the default build plate adhesion type for Nylon prints – from raft to brim.
  • Support Interface Thickness. To reduce printing time, we’ve changed the Support Roof Thickness to 0.8mm, and slightly decreased the PVA support infill.
  • Ultimaker 2+ PC prints. The raft settings for the 0.25mm and 0.4mm nozzles have been adjusted in the polycarbonate profiles – which means less warping and better print results.

First Space 3D Printed Art Piece

Astronauts on International Space Station 3d printed a first space art object named "Laugh".

From project description:
#Laugh is a collaboration between Israeli artist Eyal Gever and the California-based company Made In Space, which owns and operates the Additive Manufacturing Facility (AMF), the ISS' commercially available 3D printer.

The project began Dec. 1, 2016, when Gever and his team launched an app that converts the sound waves of users' laughter into a digital 3D model, or "laugh star." More than 100,000 people generated their own laugh stars throughout December, Made In Space representatives said.

App users then voted on their favorite laugh star. The winner was Naughtia Jane Stanko of Las Vegas, whose model was beamed up to the ISS and printed out Friday

3D Printed Metamaterial with Bit Switches

Researchers at Hasso Plattner Institute improved their 3d printed metamaterial  technique to make devices that have embedded digital or "bit" switches.

This is the preview video, more information will come in the future:

Here is their earlier work:


3D Printable Control Unit with 32 Programmable Keys

Here is a very useful DIY 3d printable control unit that can send custom g-code scripts and macros via 32 programmable keys. It can be used on almost any machine that uses g code, like CNC mills, 3d printers, laser cutters and other. It is powered with Arduino Nano. 

The "Gcode Sender" was developed and released by James Sierra. Here is his description of the project:
This project is very much like using Pronterface or Repetier Host manual control to send gcode instructions to your printer while connected to the computer via USB cable, but instead using an Arduino Nano connected to a small keypad to send the Gcode scripts/macros.
Gcode sender is intended to work for 3D printers as well as a CNC mills and laser engravers. Any machine that uses gcode.
This setup allows one to send highly customized gcode scripts/macros to the printer with a push of a button. I've tested all of the scripts I included in the sketch. Any one of them can be replaced or edited.
In the sketch, i tired to include a lot of comments to make it easier to tweak the code to suit your own needs.
Communication between Gcode Sender and printer is through serial communication (Tx, Rx). On RAMPS style boards the AUX-1 port can be used. Specifics on wiring can be found in the Wiring.zip file. Be sure that Tx out wire on the Gcode Sender is connected to Rx on printer and Rx is connected to Tx. In Repetier firmware, I had to enable Bluetooth serial port to make use of the AUX-1 port.
