The saxophone has 41 components excluding all the springs and screws, It is printed in nylon, on a SLS machine, and weighs less than a quarter of a real sax (575 grams vs 2.5 Kg. Weight might go up a tad once painted, though, but still a lot less than a metal one).
The OLED display is a small .96" display controlled by an arduino nano board. The display receives text and commands from a HC-05 serial Bluetooth module connected to the arduino. There is also a small speaker and RGB LED connected to the board. The OLED display, RGB LED, and speaker are all controllable over Bluetooth.
The device is powered by an Adafruit powerboost module connected to a small 0.7Wh lipo battery. The optics are a small mirrored right angle prism and a magnifying lense. The frame and casing is all 3D printed with ABS using a Solidoodle 2 pro printer.
The Arduino communicates with the OLED display using i2c (inter-integrated circuit). The RGB LED and the speaker use the arduino's digital output pins. The display is controlled over blue tooth using a application running on an Android phone or Linux terminal. The glasses are very portable and foldable.
Total cost ~$60.

3DPrintTech is CAD plugin for model splitting and nesting for efficient batch printing. It helps the user to print objects larger than build volume of a 3D printer. App splits the large model in small components as per your printer settings. It also creates the connectors to help you glue the components to make your original large model. User can define various parameters of splitting.From the press release:
User has an option to scale the model. Also to get separated view of split parts can use Explode.
3DPrintTech has unique feature 3D Nesting. 3D Nesting helps you combine many small components in one single printing process by 3D packing with clearance. This helps you to save time, energy and money.
3DPrintTech also provides the option of Export to save the split parts or nested parts as stl files which can be directly use for printing.
Also user can do all these processes for his/her own customized printer too by adding it to the existing list of printers.
As 3DPrintTech is developed by using Confluence Framework, it supports:
- AutoCAD 2014
- Inventor 2014
In future versions of 3DPrintTech using Confluence Framework, it will support more CAD softwares like Revit, Rhino, Creo, NX etc.
- Solidworks 2013
Pune, India - July 25, 2014 – Centre for Computational Technologies Pvt. Ltd. (CCTech), a CAD and CAM product development company, announced today launch of new application 3DPrintTech for maker community. 3DPrintTech helps maker to build object larger than build volume of any 3D printer. App also provides the functionality to pack small objects in given build volume which help to save time and money to user. 3DPrintTech is currently available for FREE of cost and works as CAD plugin with Autodesk Inventor 2014, AutoCAD 2014 and SolidWorks 2013.
3DPrintTech is designed for maker community who faces challenge to print larger objects on small 3D printer quickly. Processes of converting your design into small parts are time consuming and require good CAD modelling expertise. We realized there has to be a better way for this particular problem. Our R&D team came up with an application that can divide design of large object into small connectable components within few minutes. App also provides user option to control the cylindrical connectors as per his requirement. User can define the connector in terms of radius, length and taper angle. User also control the distance between the connectors, distance between connector and object surface.
Next problem of maker community is packing of multiple components in one print batch. One option for maker is to manually pack as many possible objects within build volume. He has to make sure that packed objects does not intersect or touch each other. To solve this problem, we provide a feature called 3D Packing. It creates the batch of 3DPrintings from collection of many small components. In our benchmarking, we found that for many cases our 3D Packing helped to reduce the 3D Printing batches from 10 to 1. This is definitely going to help makers to print more objects in less time and less money.
3D printing is continuously evolving technology. Therefore app has provided an interface to add your custom printer. App provides many utility functions such as Exporting processed objects to 3D printable STL file, Explode objects for quick inspection, scaling the object for unit conversion or fitting into printer. As 3DPrintTech works within a CAD system so you can do multiple design iterations without leaving the CAD application. All the 3DPrintTech operations are nondestructive and hence keep your design intact.
Sandip Jadhav, (Co-Founder & CEO, CCTech) says “3DPrintTech should help maker to improve productivity by great degree. It will also help maker to push envelope by making new large 3d objects. 3DPrintTech 1.0 was released on Autodesk App exchange in Autodesk University 2013. 3DPrintTech app received the great response and feedback. Out development team incorporated these user suggestions in our final product. App’s ability to create objects larger than the print volume using our automated splitting technique and packing of small components by efficiently nesting is key strength. 3DPrintTech is developed using CAD application development framework known as Confluence Framework. Therefore it works for multiple CAD systems seamlessly. In future we would provide more choices of connectors, packing types and more CAD platforms".

I also have slight suspicion that someone will want to 3d print bombs on-board of military aircraft. Still, all limitations remain. Why send something very expensive and heavy when you have proven delivery methods? Maybe some tactician is thinking of highly customized munition for very demanding missions with uncertain parameters for high-value targets.
“3D printing of warheads will allow us to have better design control and utilize geometries and patterns that previously could not be produced or manufactured,” James Zunino, a researcher at the Armament Research, Engineering and Design Center (ARDEC) in Picatinny, New Jersey, told Motherboard in an email.
The ability to print parts previously unimaginable using traditional manufacturing methods could radically open up the possibilities when it comes to what a warhead can do. For example, warheads using 3D-printed components could be designed to be more compact in order to pack in additional payloads, sensors, and safety mechanisms. Planning for printed parts in the design process will also allow the army to precisely engineer the blast radius of warheads for maximum effect.
“Warheads could be designed to meet specific mission requirements whether it is to improve safety to meet an Insensitive Munitions requirement, or it could have tailorable effects, better control, and be scalable to achieve desired lethality,” Zunino wrote.
As an organization with a shrinking budget—except when it comes to drones—the army weighs the cost of human life against that of building the instruments of its eventual liquidation. One cross-industry advantage of 3D printing is its cost-effectiveness since it enables the printing of complex structures in one go, instead of the many individual parts that go into it. Missiles are no different.
“3D printing also allows for integrating components together to add capabilities at reduced total life cycle costs,” Zunino explained. “It is expected that 3D printing will reduce life-cycle costs of certain items and make munitions more affordable in the long run through implementation of design for manufacturability, and capitalizing on the add capabilities that 3D printing and additive manufacturing can bring to munitions and warheads.”
The army doesn’t plan on stopping at merely printing warhead components, either. Eventually, they want to print the whole damn thing in one go. “Maybe someday an entire warhead or rocket could be produced as the technology further matures,” Zunino wrote.

Clay’s DIY “Google Glass” uses the sensors on the Arduino Esplora along with the Arduino LCD screen and a 3D printed frame.
He can use voice commands to bring up a calendar with his schedule, local maps, and temperature and weather info.
A headband on the back keeps it from tilting to one side.
“Now they are extremely comfortable,” says Clay. “In fact I wear them around my house and tell my parents the temperature just for fun!”

ErectorBot or EB1 is a large scale 3D printing full service gantry bot. Part of a series, our EB1 is the largest of the group. Just as in racing, we pushed the limits of precision and then bring this technology back down to size. So whether its our desktop model, 3ft x 2ft x 2ft or it’s one of the 3 larger models we offer.
You will enjoy TWICE the printable space (build area) in the same amount of space as you will find in the more conventional setups. This also allows us to treat the heat bed a little differently as well. No weight issues. Dynamics don’t change as your model grows. And neither should your wallet. The stationary bed design is modular and very low cost. And how about NOT HAVING to level the bed every model or run? We can choose our table to tip gap by extruder temp.
Here is one of my many projects. I thought our YouTube subscribers might get a kick out of this one. Some of you might know that I'm into old British cars, and have been my entire life. They are stylish and sexy. They are quirky and failure prone. Early ones have such serious safety issues I'm surprised any of us ever survived driving them all these years.
The stock Triumph TR3 has only one center brake light and if it fails, people run into you. That is why most early cars have been tagged in the rear. The right and left tail lights are only used as runner lights and turn signals. I wanted a quick and easy way to add brake lighting before making a bunch of wiring changes to the car. In the near future I will be adding relays in the tail to convert the function of the bright element of the 1157 dual element bulb to be not only turn signals but also brake lights. I have already designed and printed the 3D parts needed to mount the relays and will do another video if people are interested.
In this video I show how I added simple LED panel lights to serve as brake indicators in the existing tail lights with no other modifications. It takes a 3D printer to make the parts, and I'm sure several people will be interested in how the parts are made as well.

There are many benefits to FilaSoy over currently available filaments. The melting temperature of FilaSoy is lower than other filaments in the market, which saves energy costs. It also has a higher Young’s modulus than PLA (a common filament used for 3D printing) for greater resistance to deformation. This allows users to create a wide variety of products such as toys, specialty parts, models, art, and more.
The concept of FilaSoy is not simply to generate a generic material for the currently available products. FilaSoy also brings a renewable, cost effective product (soy) as an additive to the current available market while changing the properties of the material for other purposes and significantly reducing the cost of production. Since FilaSoy is renewable and derived from plant matter, it is green, recyclable, and maintains superior quality.FilaSoy specifications:
- Function: S3D Innovations’ FilaSoy is the next generation 3D printing material. Replace harmful petroleum based plastic with low energy, low temperature, and all renewable based filament. Retain similar properties found in PLA with an added green twist. Print your prototypes, designs, models, and more without worrying about waste. This product is completely renewable and recyclable.
- To Use: Insert filament end into 3D printer head or as instructed in your 3D printer manual. Set the temperature at 220/230°C. For best results please iterate printer setting until filament extrudes smoothly.
- Ingredients: FilaSoy is composed of approximately 20-25% soy-based materials and raw polylactide pellets.
- Safety: FilaSoy has a very low degree of toxicity under normal conditions of use. Caution is advised when handling, storing, using, or disposing. Keep in cool and dry storage area. Do not use with food or ingest. Potential choking hazard. Keep away from children and pets.
