Learn about what a 3D Printer is and how they work from MakerGeeks.com

(from Wikipedia)

Additive manufacturing or 3D printing[1] is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes.[2] 3D printing is considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes).

A materials printer usually performs 3D printing processes using digital technology. Since the start of the twenty-first century there has been a large growth in the sales of these machines, and their price has dropped substantially.[3]

The technology is used for both prototyping and distributed manufacturing in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many other fields.
The first working 3D printer was created in 1984 by Chuck Hull of 3D Systems Corp.[4]

To perform a print, the machine reads the design from an .stl file and lays down successive layers of liquid, powder, paper or sheet material to build the model from a series of cross sections. These layers, which correspond to the virtual cross sections from the CAD model, are joined together or automatically fused to create the final shape. The primary advantage of this technique is its ability to create almost any shape or geometric feature.

Printer resolution describes layer thickness and X-Y resolution in dpi (dots per inch),[citation needed] or micrometers. Typical layer thickness is around 100 micrometers (µm), although some machines such as the Objet Connex series and 3D Systems' ProJet series can print layers as thin as 16 µm.[6] X-Y resolution is comparable to that of laser printers. The particles (3D dots) are around 50 to 100 µm in diameter.

Construction of a model with contemporary methods can take anywhere from several hours to several days, depending on the method used and the size and complexity of the model. Additive systems can typically reduce this time to a few hours, although it varies widely depending on the type of machine used and the size and number of models being produced simultaneously.
Traditional techniques like injection molding can be less expensive for manufacturing polymer products in high quantities, but additive manufacturing can be faster, more flexible and less expensive when producing relatively small quantities of parts. 3D printers give designers and concept development teams the ability to produce parts and concept models using a desktop size printer.

News from the Maker Desk

News from the Maker Desk
Happy Monday to you... hope you are doing great today; wanted to share something that was on my heart this morning about MakerGeeks and what’s going on and what the next steps are for us.

Almost 3 years ago we started selling 3D Printer filament(all of it from China) and over the next 2 years saw a booming business come out of those items; reselling filaments from China, Germany and the Netherlands. About a year and a half ago we started with a single extruder and a dream to start making 3D printer filament in bulk scale here on US soil… back then I thought that 1 extruder and me working part time would make more filament than I could sell in a life-time. Well, within just a few months we had bought another extrusion line and hired our first full time operator just to keep up with demand.

Now, surly we would have enough filament to last a life-time; NOPE… in just a few more months we added another extrusion line and lots and lots of overtime and weekends. Now we…
