Uma Impressora DLP por 60 dólares! Outra por menos de 500, mais Crowdfunding em Português, e

As Impressoras DLP são as que resultam numa Impressão mais fiel ao modelo, nada das "escadinhas" das Impressoras FDM, de Exrtusor e Filamento, e agora, podem construír uma, com 60 Dólares, o que é fantástico!
Com umas tralhas que praí tenham, um Projector Vídeo em 2ª mão, e um DVD velho, mais isto e aquilo, vão poder fazer esta pequena Maravilha: 




Chimera: $60 DLP High-Res 3D Printer

matstermind

I have been on a hunt for the past several years to find a cheap and simple, yet moderately high resolution 3D printer. I had 3 different 3D printers partially constructed when I heard about the amazing technology of DLP Stereo lithography (SLA) printers. I have finally found enough parts at the right price to construct a fully functional printer capable of amazing quality with spending less than $100. Top down DLP printers in their simplest form have only one axis of motion, a video projector, and minimal electronics. They do not require a heated or perfectly level bed, there is never a clogged or wrong temperature in the extruder as it does not use an extruder. And the resin used has a comparable price to FDM printers.
The chimera (ky-meer-a) is a mythological creature that is made up of 3 different animals, this printer is made using the recycled/modified parts of 3 different categories (projector, toys, and old computer stuff), hence the name.
I am always looking for constructive criticism, let me know if you think i can improve on the project, or the instructable!

E se quizerem uma Impressora capaz de imprimir objectos maiores, têem esta, que fica um pouco mais cara, mas faz com que a diferença valha a pena!
E, francamente, é bem mais sólida.





"Little Dipper" SLA/DLP 3D printer for under $500 (projector included)

A brief overview:
This Instructable is about building a simple yet versatile resin (SLA) 3D printer that uses a cheap DLP projector to build the part from the "top down". This orientation of the light source is similar to other large scale industrial SLA machines. It has some advantages in simplicity, scalability and disadvantages in minimum feature size and print time.
This version build is budget conscious, has a low part count, can easily be upgraded and scaled in size. The entire 3D printer (projector and resin included) can be built for just about $500 or less which makes it one of the cheapest bang-for-your-buck 3D printers using SLA resin out there.
There are many good Instructables and resources that contain more exhausting detail about DLP resin 3D printers and background information. If you are interested in learning more about this http://www.buildyourownsla.com/forum/ will be one of your best community resources for knowledge relating to the topic.

Dica do nosso amigo José Abrahão, eis mais um site de Crowdfunding que fala esta mesma língua, de origem Brasileira, tomem nota.
E esta tem uma particularidade, a de vocês conservarem os fundos acumulados, MESMO se não atingirem a Meta pretendida!
É bom!

.. E uma proposta que não podem recusar, um Drone Kit, para transformar não importa o quê, num UAV, um Projecto tão maluco, que TEM de ter muitas utilidadfes práticas, eventualmente...
Em que ninguém tenha pensado!

DIY (Drone It Yourself) Kit v1.0

javl

The DIY (Drone It Yourself) v1.0 kit offers you the opportunity to turn any object into a drone (or technically, an UAV). The kit consists of multiple parts that are easy to assemble and can be attached to a wide range of different objects.
For more advanced uses, you can take the original designs and alter the kit by making your own custom clamps or add-ons as needed.
The plastic parts have been 3D printed in ABS. The control unit contains a receiver, four ESCs, a bluetooth module and an Flight Controller. I've provided a list of the hardware and electronic parts I've been using, but feel free to try your own combination.
