Arc Printer Design Document
Purpose and Scope
This document will describe the currently being developed Arc Printer in detail and provide information on what process I intend to follow in the developement of the Arc Printer.
Project Executive Summary
This project's intent is to improve 3D printers in respect to print time. 3D printers are incredible technology but are limited by the speed at which the produce printed objects. The Arc printer aims to remedy this by utilizing a technology already in use in welding arc welding(a process of electrical fusing of metal) and also eliminate the need to move the print head.
The Arc printer is made of four main components the print bed, the lifting device, the conrol box, and the granulated metal supply bin. The control of the Arc Printer will be by a standard computer that will send the object to be printer to the Arc Printer.
System Hardware Architecture
The main components of the Arc Printer work together to print an object layer by layer. First the granulated metal supply bin provides a thin layer of granulated metal(possibly using mild vibration) onto the print bed. Then the lifting device is lowered within electrical contact of the granulated metal. With the lifting devices electrical base in electrical contact with the granulated metal the control box begins by printing out a lead by sending electrical pulses to the print bed wire array and raising the lifting device. After the lead is made the object printing begins in a center out fashion. For computer to printer communication I will use USB.
System Software Architecture
the system firmware will control the pre-print procedures and post-print procedures this also includes layer printing. The computer driver will handle file translation to printable layers and provide print options.
I intent to design the software to handle most standard 3D object files through the drivers.
The system will act as most any paper printer as the control on the device will only consist of a power button and a reset button. The main human interface will be through a computer system and the drivers for the device.
