Graphene Filament Could Breathe Life into 3D Printing

5 08 2015

Os copiamos el articulo de Tarum Tampi sobre filamento de grafeno y sus posibilidades.

By On Thu, March 19, 2015 · 3D Printing, Materials, News 5 Comments

Stronger than diamonds, more conductive than copper, more elastic than rubber, and now available as a 3D printable material, Graphene has well and truly arrived, albeit as a PLA composite. The thinnest and strongest material known to mankind, infused into a PLA filament, is finally available at $65 for 200 grams. 3DPI had reported last month that the material was due for commercial release sometime in late March. As of March 16, rolls of conductive graphene filament can be purchased at blackmagic3d.com (the brand & e-commerce platform for Graphene 3D Labs Inc) for use in almost any desktop FFF/FDM 3D printer.

The release of this ‘wonder’ filament, as part of a trend of conductive 3D printing filaments and the Voxel8 multimaterial 3D printer, historically marks the beginning for 3D printing electronic devices on the desktop and is the first graphene 3D printing material of its kind. Amazingly, it can be used under the same conditions as non-functional thermoplastics like ABS and PLA.

Graphene filament opens up several design possibilities, most importantly in the creation of conductive traces, which allows you to 3D print an object and its circuitry simultaneously. Although currently, the PLA-based filament is restricted to low-voltage (less than 12V), low current (less than 100mA), and room-temperature (less than 50®C) applications, it would still find extensive use in designs for LED’s, wearable electronics, and custom electronic interfaces. Perhaps, it would also be the final key in unlocking the doors to the creation of an exhaustive and complete Internet-of-Things.

It also enables the one-step printing of other, more commonly used interface devices with conformal and embedded touch sensors. Re-designing gaming controllers, drum machines, MIDI controllers, trackpads, and digital keyboards has just become a whole lot easier. This could mean that we can expect to see a range of highly personalized, yet affordable, digital devices manufactured on-demand in the near future.

Additionally, the filament could be used to create customized EMI/RF (electromagnetic/radiofrequency) shields for crucial applications in the telecommunications, medical, aerospace, and packaging industries where it is vital to protect signals from interference by AM, FM, TV, emergency and cellular signals. Incredibly, the filament is special not just for its electronic properties but its mechanical ones as well. It has greater strength and durability than ABS and PLA, so hooks, hand-tools, drills and other tooling parts can be 3D printed for use in more robust applications.

As Daniel Stolyrov, CEO of Graphene 3D, has said, “This is an important milestone for Graphene 3D Lab, achieving revenue through the commercialization of functional 3D printing materials and in achieving the Company’s goal of building an ecosystem for 3D printing operational devices.” All in all, the release of the much-anticipated conductive graphene filament may emphatically breathe life into 3D printing.

Maquina DLP opensource

31 07 2015

Presentamos un articulo interesante de construcción de una SLA de bajo coste.

Jun.24, 2012

Ron Light from Kansas City has developed a cheap DLP 3D printer and is right now crowd funding on Kickstarter. His design uses a top down approach which requires more resin but the mechanics of the printer are simpler.

This resin-based 3D printer project is named as Sedgwick open source 3D DLP printer, same as other resin printers, it uses a standard DLP projector to cure the print one layer at a time. The build area is not very big, about 76.8mm x 102.4mm x 125mm (3in x 4in x 5in) but the print speed can be as fast as 5mm per minute or more.

On Kickstarter the Sedgwick open source 3D DLP printer kits are available for $495 with everything required except common tools and the projector, and you can also get your first 2 Liters of resin for free. Ron Light advises that an Acer X1261P 1024×768 DLP Projector can be used for this printer, and it will cost around $350 to $450.

“The goal of this project was to create a low cost, high resolution 3D printer.” So this printer uses laser cut wooden frame to lower the cost, and according to Ron Light, the price of resin can be around $80 to $100 per liter if there is enough people support the project. As to the resolution, “Sedgwick was designed to only print at 100 microns (0.1mm) in the x-y.”

This project will go open source but if you pledge $25 now you can get an early access to design documents and software. Check out the video below of the kickstarter project after the break.

Alimentos impresos en 3D

20 06 2015

Escrito por johanna.sch ; Nutrition & Health | Online Communication

“La impresión 3D es una tecnología que ha ido suscitando cada vez más interés en los últimos años. También conocida como fabricación aditiva, la impresión 3D describe un proceso en el cual se crea un objeto de manera sucesiva, capa a capa, hasta formar un todo. Basada en los modelos electrónicos, la impresión 3D es capaz de producir cualquier cosa; desde juguetes hasta lencería, pistolas y prótesis de extremidades, y ofrece múltiples posibilidades para modificar los procesos de fabricación en el futuro. Entonces, ¿por qué no hacer comida?”

Los alimentos impresos en 3D también tiene muchas ventajas:

  • Producción según demanda: solo se imprime lo que se necesita, reduciendo el desperdicio
  • Los astronautas pueden disponer de alimentos variados en el espacio, y los soldados en el frente pueden tener acceso a alimentos de manera segura
  • Los alimentos impresos pueden enriquecerse fácilmente con vitaminas y elaborarse a medida según las necesidades nutricionales específicas del consumidor
  • Las regiones remotas tendrían acceso a alimentos saludables
  • Pueden adaptarse fácilmente a las personas con alergias y restricciones en la dieta
