Delta Flying Extruder

Direct and Bowden extruders both have their limitations and advantages. Flying extruder for Delta 3d printers should have the best of both types.
Flying extruder should have few key advantages:

  • Remove weight from the moving portion of the printer, making momentum shifts much easier
  • Remain “close” to the hot end to enable effective printing of flexible materials and remove tube friction
  • Reduce motion “lag” caused by lengthy tube traversals
It was introduced on RepRap forum thread:

http://forums.reprap.org/read.php?178,218716

It was described as:
The extruder is suspended by rubber bands. These are running around several rolls to increase the length (each around 2m relaxed) to have more or less the same force over the whole vertical range. The extruder is connected with a very short latex tube (around 75mm) to the nozzle. This tube decouples the high frequencies between the nozzle and the extruder.
Long story short: I'm printing with no problems with 75m/s and 3mm retraction and still with the same acceleration of 800mm/s². But this was only a short test and I think I can bring it up with a bit optimization.
Another advantage is, that it's now easier to build an enclosure and that the printer is much quieter, because the extruder is decoupled.



Here is a video of flying extruder in action. The developer claims that the strange motion is due to Kisslicer and that prints are very good.

Cambits use 3d printed enclosures for modular camera system

Shree Nayar and Makoto Odamaki, scientists at Columbia University, developed a modular camera system made with 3d printed enclosure named Cambits. Electronics is the main part of technology and 3d printing is just gives the structure and housing. Still, very interesting piece of engineering and research.

There are five different type of Cambits: sensors, light sources, actuators, lenses, and optical attachments. The blocks can easily be assembled to make a variety of cameras with different functionalities such as high dynamic range imaging, panoramic imaging, refocusing, light field imaging, depth imaging using stereo, kaleidoscopic imaging and even microscopy.

Zowi is further development of BOB robot.

Ardumower Arduino Controlled 3D Printable Lawn Mover

Andreas Haeuser developed a 3d printable lawn mover. It is controlled by Arduino and looks easy to build on any FDM machine with some electronics knowledge.































Tech specs from the project page:
The 3d printed ardumower works on the same principle as its commercial counterparts, which can be bought for a lot of money at most hardware stores. It drives in the inner space of a “boundary wire fence” (BWF). If it comes close to this it stops, turns and then it goes on mowing your lawn continuously. The ardumower is well tested for a lawn size up to 500m². If your lawn is bigger you need a second battery or you should print a second ardumower.

In addition to a 3D printer and the needed filament (ABS and PLA) for printing the parts, only a few tools and resources are needed to build the chassis. These are mainly common hobbyist tools. You do not need a lathe or a milling machine. Every common 3d printer with a build volume of minimum 180mm x 180mm x 60mm (x,y,z) is suitable.

The ardumower is driven by two 12V geared motors. The cutting device is made from a 12V DC-motor and a cutter disc with a diameter of 220mm. The power comes from rechargeable 12V NiMH or 11,1V LiPo batteries.

3D Printed Monolithic Houses

Andrey Rudenko developed his own concrete 3d printer in the garage. It has a gantry motion and extrudes concrete paste combined in the optimal mixture.
In his latest demonstration he printed a 100m2 house in 48 hours. He claims his 3d printed structures are hurricane and tornado resistant due to monolithic design.

He also successfully 3d printed a hotel suite in the Philippines:
































Here you can see the process and comparison to human builders:



He is well known for his 3d printed concrete castle:




His homepage with much more information:

http://www.totalkustom.com/


PS: I like the technology, but 3d printing is not a solution to housing crisis in my opinion. Houses are cheap to build, what is expensive is land, permissions, architectural work by certified professionals, compliance etc. Houses also became financial instrument and not a physical object person lives in. It is a broad and complex issue.

Taiwan Launches 3D Printed Rocket

Taiwanese university launched 3d printed APPL-9C rocket. It is made from modules with many 3d printed subsystems. It should be part of a larger multistage rocket in the future. Looks like many of the parts were done on FDM machines. I always claimed space will be colonized with 3d printers.

The first section of the rocket uses a sugar-based rocket fuel made from sorbitol + KNO3, and its second section features a hybrid rocket motor fueled by Hydroxyl Terminated Polybutadiene HTPB, with nitrous oxide as the oxidant. It accelerates at 15G.




From the source article:
A locally designed, developed and constructed rocket blasted off Jan. 31 in Hsinchu City, signaling Taiwan’s commitment to furthering its space technology capabilities.
Produced by Advanced Rocket Research Center based in National Chiao Tung University, the two-stage APPL-9C reached an altitude of 1 kilometer before deploying three chutes and splashing down in a Hsinchu wetland.
The rocket, made from environmentally friendly materials, measures 2.7 meters in length, 15 centimeters in diameter and weighs 27 kilograms when fully fueled.

How To Repair Broken Eyeglasses Frame with 3D Printing

Since I wear eyeglasses since my early childhood, I have broken them may many times. To repair the frame is not easy and replacement is always costly. You can use some superglue or other hacks but it's problematic if the part has shattered in several pieces or you just can't find it.

Matias Mamone published his tutorial on Instructables featuring a easy step-by-step process how to design the broken part and 3d print it to make a solid bridge to fix the frame. Nice! Thank you Matias for this cool tutorial!

3D Printable Dactyl Ergonomic Keyboard

Matt Adareth developed and released his "Dactyl" ergonomic keyboard under CC license. This open source keyboard is described as “parameterized, split-hand, concave, columnar, ergonomic keyboard.”
As you can see it was 3d printed on a SLS machine but it could be probably made using other machines with some adjustments.

You can see a very interesting presentation by Matt about keyboard design and 3d printing at:

Ultimaker 2 Vs. Print-Rite Who Wins?

Guys from Make.Test.Battle,Ryan and Kash do a casual comparison of the Ultimaker 2 and the Print-Rite DIY 3D Printer from HobbyKing, as well as learn the importance of bed leveling. 
They do a lot of Nerf toys modifications and upgrades with 3d printing. 

It turns out you really get what you pay for in this case. 

Why are 3d printers so expensive in Australia? Probably due to shipping, import and customs fees ... taxes maybe?

Here is a complete comparison video:

Cardboard Box 3D Printer Enclosure

This guy made a very cheap 3d printer enclosure made from cardboard box :-) It probably works and can be used as improvised heat chamber but there could be a slight fire hazard. But if you don't have any money, you will take some risks. I know that for a fact. You could also try using some salvaged drywall or gypsum plates.
Stay safe kids! It's always a good idea to have a fire extinguisher in your house.




If you need a different low cost solution you could try this one with cheap plastic boxes:

Educational TETRIX 3D Printer

Tetrix is a new 3d printer design based on needs of schools to provide simple and affordable teaching tool.



























Here is the project description:
The TETRIX 3D-Printer was designed as an educational tool for middle and high school technology students, robotics teams, and adults. The purpose of constructing the printer is to train people's building, tool usage, electronics, CAD, and programming skills with a single project. You also get a 3D-printer once you're done!
The printer design is based on TETRIX parts, which are designed by PITSCO and used in the FIRST Tech Challenge robotics competition. The printer also utilizes elements of various RepRap printer designs, such as the Printrboard control system. The design is completely open-source, so feel free to personalize and alter your printer.
The overall cost of the printer is about $640, and the educational value is priceless! The majority of the cost is attributed to the TETRIX parts, but the high accuracy of the pre-drilled, pre-sized aircraft-grade aluminum saves time and reduces error, which outweighs the price.

Prusa I3 Based Ultrasonic Laser Resin 3D Printer

Team of scientists hacked a Prusa I3 to develop new 3d printing process that uses laser to solidify ultrasound arranged resin fiber particle in a small vat.
A laser diode module was mounted on the print head to cure the resin, with an emitting power of 50 mW. The laser diode was housed in a shroud, and was focused using a single 6 mm diameter lens, with a focal length of 20 mm. The small vat sized at 35mmx35mm was filled with low viscosity photocurable resin (Spot-A LV) and commercially sourced glass microfibres (Lanxess MF7904, length 50 μm, 14 μm). Ultrasonic transducer gives resin floating fiber the shape and laser solidifies it.
It is a new form of stereolithography which could see some upscaling into more capable machines.

Linespace Tactile Interface for the Blind with 3D Printing Extruder

Linespace is an ingenious device that uses a 3d printing extruder to produce a large tactile interface for the blind. I love this project! This could be extremely useful for the blind people!

Project description:
Linespace is a tactile display system for blind users. The foundation of our system is a large 140x100cm display area, on which the system creates raised tactile lines with the help of a 3D printer. The foot switch allows users to enter text and issue commands by talking to the computer.

We use Linespace to give blind users access to the type of software packages that normally only sighted people can access, namely the type of software that helps them to make sense of complex data. So far, we have created a simple homefinder program, a spreadsheet program that can read and write Microsoft Excel, two simple games, and a simple programming environment.

One might say that Linespace is an interactive "visualization" system for the blind. The key to achieving this is Linespace large display as it allows displaying a lot of contents at once, where smaller display systems need to update screen contents. The use of lines (instead of the more common Braille dots) helps create visualizations.

The vision behind Linespace is to help blind users interact with and make sense of complex spatial data. It thereby intends to pick up the vision behind of Vannevar Bush's memex, Engelbart Online system, and Xerox PARC's personal computer, by investigating how we can recreate this type of interaction for blind users--how to use computers to help people think better.

In the video you see a user using this system to find homes in Berlin:

SprintRay MoonRay High Resolution UV DLP 3D Printer

SprintRay presented their MoonRay high resolution UV DLP 3D printer. It will be priced at  3499 USD.















Key features:

  • Custom-built projector for 3D printing fine details: MoonRay’s resin requires UV light for proper curing. Other similar 3D printers use commercial projectors, which produce visible light but not pure UV light. The advantages of the custom UV LED projector in MoonRay are in the resolution and curing process. The MoonRay’s UV projector, RayOne, was custom designed with some special qualities:
  • Perfect light spectrum: The resin used for 3D printing cures under light with a 405nm wavelength. The custom-built projector hits the proper wavelength consistently across the build platform, which allows you to get real 100-micron resolution.
  • Runs cool and quiet: Utilizing a UV projector allows the MoonRay to avoid any overheating and makes it much quieter than other 3D printers.
  • Long lifespan: RayOne’s 50,000-hour lifespan means you won’t ever need to replace the bulb.
  • Revolutionary resin tank: the team designed the MoonRay’s resin tank to last, so there’s no more replacing your printer’s resin tank or changing the PDMS layer

Someone note in the comments that this is a CNC router. So, what is a different between CNC mill and CNC router?

"A CNC router will usually have a large X and Y range and short Z... A router will typically be able to do soft materials like wood, plastic, and maybe aluminum... But overall, it won't have the most rigid structure (like this one which is 3d printed)

A CNC Mill will have a relatively smaller X and Y with a larger Z than a router... A mill will be able to cut hard materials like steel... And thus will have a very rigid structure so that it can accurately cut those materials."
