How to design and 3d print an electric guitar

Olaf Diegel is custom 3d printed guitar maker who will guide you trough the process of creating a fully functional SLS 3d printed electric guitar.
You will need the access to more serious equipment like SLS 3d printer and some tools, but they are much more available now and will probably be ubiquitous in the future.
The bodies of his guitars were 3D printed out of Duraform material (Nylon), on a 3D Systems sPro selective laser sintering system (SLS).

How does the 3d printed nylon guitar sound? Here is the answer:

He also made a 3d printed saxophone.

Update (27.9.2014):

Olaf Diegel organized "first concert" of live band that plays with 3d printed instruments:
The first live concert with a band consisting only of 3D-printed instruments has taken place at Lund University in Sweden. The band included a drum, keyboard and two guitars, all 3D-printed by Lund University professor Olaf Diegel. The band members were students at Lund University’s Malmö Academy of Music.
As some comments say, the drums may sound somewhat hollow and electric guitar is not effected by acoustic properties of the body but more by electronics and coils. Still it is a nice accomplishment.

Demonstration of 3d printed nylon saxophone

Olaf Diegel usually makes 3d printed guitars, but now he made a saxophone.

Saxophone data:
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).

Video tutorial on how to use Marlin EEPROM functions

You can store Marlin setting directly in EEPROM memory. On each boot, Marlin will automatically load these settings from EEPROM, independent of what your compiled Configuration.h says.

The Marlin EEPROM settings include the following:
  • Steps per mm
  • Maximum feedrates [mm/s]
  • Maximum Acceleration [mm/s2]
  • Acceleration
  • Retract Acceleration
  • PID settings
  • Homing Offset
  • Minimum feedrate [mm/s]
  • Minimum travel feedrate [mm/s]
  • Minimum segement time [ms]
  • Maximum X-Y jerk [mm/s]
  • Maximum Z jerk [mm/s]
Another excellent tutorial by ZennmasterM! He is producing some high quality video tutorials in field of 3d printing.

Here is also an additional post from Solidoodle wiki about Marlin EEPROM functions: 

3D printable low cost foldable Bluetooth head mounted display

Tony created this very cheap piece of DIY wearable eyespace technology. It is foldable wearable display that connects via Bluetooth with your Android or computer.

Everything displayed on this head mounted display is controlled by either an Android phone or a Bluetooth connection to a desktop. Using relatively simple display and simple Arduino means it is limited to text and very simple graphics, but this is more than enough for some useful applications like reading SMS messages and checking email.

From project description:
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.

Kudos Tony!

3DPrintTech is a free CAD plugin for model splitting and nesting for efficient batch printing

3DPrintTech is a free software from India that will enable you to print objects larger than your printvolume by splitting them into smaller modules.

From the homepage:
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.
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
  • Solidworks 2013
In future versions of 3DPrintTech using Confluence Framework, it will support more CAD softwares like Revit, Rhino, Creo, NX etc.
From the press release:
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".

Erectorbot large volume 3d printer and Erectostruder pellet extruder

Erectorbot is new large volume DIY 3d printer developed by Leonard Dodd. Beside large volume it features exchangable heads for a CNC plasma cutter, router, and welder.

From EB1 homepage:
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.

It will be priced at range of $11,500 to $35,000.

Erectostruder is pellet 3d printing exruder that can also be mounted on EB1 that can use different types of materials and be used as a filament extruder.

  • Runs even the small Nema 17 and powerful doing so.
  • Shift-able planetary gears (high -Low)
  • Easy clean up (4 thumb screws)
  • Extreme temp range – frozen slush to 300 C
  • Resolution – the smallest standard up to 2mm
  • Customization – steam punk ~ beer still- high tech (3 themes thus far)
  • Liquid Cool compatible
  • High volume hopper options – laser vac
  • Twin element for precise control
  • Two sized augers for different sized pellets.
  • Arduino micro kit (stand alone ) filament extruder mode. (Yes doubles as a filament machine.)
  • All metal main components, ultra light, TIG welded, hand crafted by a master metal modeler and serialized.
  • Quick mount/release.
  • Multi head compatible.

Hacking vintage Triumph TR3 car with 3d printing

In this video EpicenterBryan shows how he modified his vintage cars tail lights with a help of 3d printing to install LED lights for more safety. You can call it modifying but I call it hacking. Realistic and usable merger of new and old technology.  It is also an tribute to DIY culture and handcraft since there were no robots involved in production of this Triumph.

He writes:
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.

FilaSoy is soy based 3d printing filament developed by Purdue University students

Team of students from Purdue University developed a new 3d printing filament made from polylactide (PLA) which is made from corn, starch, tapioca root and sugar cane and  20-25% soy materials.

FilaSoy key advantages:
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.

Protoprint will produce filament from garbage in partnership with Indian waste pickers cooperatives

Protoprint is a social enterprise based in India that empowers waste pickers with the technology to produce 3D printer filament from waste plastic. They set up their waste plastic processing and filament extruder near waste sites and work in partnership with waste pickers cooperatives to establish the supply chain and provide more earnings for waste pickers.

Protoprint also sells 3d printers and wants to establish community 3d printing centers. 
Very interesting story, I hope we will here from it more in the future.

Esun nozzle cleaning filament

Shenzhen based Esun company sells the filament they developed that should clean your extruder and nozzle.
Composition of this filament is unknown but it is probably similar to nylon. Nylon filament is used in a cleaning process where it is extruded at 200 C and then cooled to 135 C which hardens it and makes it attract and clean up all the particles that clog up the extruder. Like all similar cleaning methods, this one can also fail.

There is not much information or reviews available around, so if you know something more about this or have any practical experience with it  let me know ...

Genkei gigantic 4 meter tall Magna Delta 3d printer from Japan

Genkei is comapny from Japan that produces 3d printers. They made this enormous 4 meter tall Delta 3d printer. I think it is not designed to be real production printer, but more of a demonstration and promotional project.
It will use pelleted material for extrusion instead of filament. It makes perfect sense for this size of machine.

The 3d printer will be on display at the Tokyo National University of Fine Arts and Music Museum, as part of an “Materializing II” exhibition that runs from Saturday, July 19 until Friday, August 8.

MakerBot starts to sell their printers in Home Depot. Is this the beginning of the end for Home Depot?

Red Pill Philosophy has an interesting opinion on this business move. The point is that the Home Depot is selling the technology which will drive it out of the business at the end.
Maybe this is unrealistic, because Home Depot and other retailers are adaptable. But there will probably be some measurable impacts on this sector from home digital fabrication soon. Probably the companies that base they business model on overpriced plastic pieces will go have massive losses. Ant there are many of those companies.
