My name is Saulo Quevedo,'m finder, live in Carmo da Cachoeira, Minas Gerais, Brazil and I'm finalizing the draft Printer Delta 3D/CNC whose name is Big Brother Spectrum. See link and more pictures:
I like the TV show that is very popular in my country
(Big Brother) and refers to the big brother United States and its major contribution to the advancement of all peoples. So I gave this name to my first printer: Big Brother Spectrum.
This printer Delta 3D/CNC whose project I'm finishing arose from the need to make my own future plastic parts in 3D large sizes (maximum print area: 1000 x 1000 x 1500 mm.). The Delta system (three drive motors) is more reliable, economical and efficient compared to other systems RepRap and the use of special Spindles and Nuts (for auto torque and speed too) much improve the quality of 3D printing and CNC and also possibility of change of application for different working modes for this printer, either for making 3D parts or performing other jobs in CNC.
The easy use of sets of spindles 3D/CNC this printer instead of the common use of the drive belt and pulley system provides greater functionality and much higher quality printing, 3D printing is (zones 2.5 mm, 3.5 mm.) or CNC (screws 4.5 mm, 5.5 mm for Plasma, Laser, Router, manufacture of printed circuit boards, etc ...)
Simply just change the set of zones corresponding step as you work it wants to accomplish.
The exchange zones is quick and with a few adjustments in the printer system can already be used for another purpose, specific to that set of zones that will be used.
Few components, self replicating (including manufacturing of parts to be used in her or others), almost any printer can be manufactured in ABS plastic or Polyacetal (screws, nuts, pulleys and rails of motion) and its final cost will not be very high when compared to the cost of other RepRap 3D printers that are out there, for what could endears it and I have sought to eliminate, was the self cost of ball screws, but using plastic or ABS type Polyacetal (compared to steel) the cost will purportedly enable smaller and finally it has a printer 3D/CNC large size, high print quality and efficiency, whether for private or business use.
Will use the mechanism of four pulleys with special self-lubricating bearings for perfect fit and no slack in spindles, nuts and special high torque to the drive assembly (triune) three arms to move Tray Central, where you can be fixed type tool you will use for each type of job that the printer can perform. In due course, I believe in using a system with ultraviolet light with photosensitive resins powder to print jobs in 3D but I'm still researching and trying to find the best solution. Meanwhile 3D printing can be made with threads of 1,5 and 3,0 millimeters from ABS, no problems. Accepted donations and all money raised will be used for installation in a suitable shed and buying all the stuff that she will need (most of the parts will be ordered only once, since I can replicate them when the printer is already ready).
I hope you enjoyed and thank you for your cooperation, see below links to other inventions created, some projects are still in the process of refinement and finish once this project is completed my first printer Delta 3D/CNC because almost all projects below need to be made to the cutting of copper and other materials and construction of plastic large size.
1 - Dyno Spectrum: Moto four and three wheels: There will be almost all plastic (ABS and others) with degree of inclination of 56.5 degrees and up to 40 degrees of steering, electric motor system with five-speed electronic and also differential (electronic system for four wheels), high-tech!
4 - Forest Donkeys in modules (1.2 Mts Width) with signage night.
Mounted on top of concrete blocks stackable for easy and safe installation. It can be mounted side by side two or more mats size that is more convenient in length or width. The assembly modules also apply to build bridges of small size or medium-size (larger bridges may be made under special design) to check link:
