AxiDraw

The AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with your favorite fountain pens, permanent markers, and other writing implements to handle an endless variety of applications. Its unique design features a writing head that extends beyond the machine, making it possible to draw on objects bigger than the machine itself.

3D Printer

3D printers machine are booming. In 2005 there are begin and 10 years later there are million. There are currently million of people wanting to start their own build waiting for the right moment to get started.

To day this project that it is very cheap and easy for do it by my hand. It’s an open-source project meaning that all the information and design plans you’ll need are available free for all. Building a 3D printer yourself is a huge undertaking. You can build it for less than $300 but months and all parts of the printer very lot can buy it online easy

Building a 3D printer is very hands-on and will require all your technical skills. There isn’t really any void that needs to be filled since there are enough people and good information online to answer your questions and help you out. Still there hasn’t yet appeared one book that guides you through building your own 3D printer.

this image 1 shows a fully assembled working home-built 3D printer. It is called RepRap 3D printer and i costs about $300 in parts. You can buy this printer as a kit but then you will pay at least double this price. Many people source the individual parts themselves and once they receive them get started on their build

3D Printer

3D printing, also known as additive manufacturing, refers to processes used to synthesize a three-dimensional object in which successive layers of material are formed under computer control to create an object.Objects can be of almost any shape or geometry and are produced using digital model data from a 3D model or another electronic data source such as an Additive Manufacturing File.
The term 3D printing has its origin sense, 3D printing in reference to a process that deposits a binder material onto a powder bed with inkjet printer heads layer by layer. More recently, the term is being used in popular vernacular to encompass a wider variety of additive manufacturing techniques.
Early additive manufacturing equipment and materials were developed in the 1980s.In 1981, Hideo Kodama of Nagoya Municipal Industrial Research Institute invented two AM fabricating methods of a three-dimensional plastic model with photo-hardening polymer, where the UV exposure area is controlled by a mask pattern or the scanning fiber transmitter.But on July 16, 1984 Alain Le Méhauté, Olivier de Witte and Jean Claude André filed their patent for the stereolithography process. It was three weeks before Chuck Hull filed his own patent for stereolithography. The application of French inventors were abandoned by the French General Electric Company (now Alcatel-Alsthom) and CILAS (The Laser Consortium). The claimed reason was “for lack of business perspective”. Then in 1984, Chuck Hull of 3D Systems Corporation developed a prototype system based on a process known as stereolithography, in which layers are added by curing photopolymers with ultraviolet light lasers. Hull defined the process as a “system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed,” but this had been already invented by Kodama. Hull’s contribution is the design of the STL (STereoLithography) file format widely accepted by 3D printing software as well as the digital slicing and infill strategies common to many processes today. The term 3D printing originally referred to a process employing standard and custom inkjet print heads. The technology used by most 3D printers to date—especially hobbyist and consumer-oriented models—is fused deposition modeling, a special application of plastic extrusion.
