3D Printer and 3D Printer Rapid Prototyping

By: Ryan Rounds

In the 3D printers available in the market these days,generation of output takes place from programs of mapping which support 3Dmodelling programs or 3D CAD programs. Some companies have their own soft waresfor PLY, VRML, and STK formats to allow 3D viewing, scaling and labeling oftext, and fine-tuning preceding printing.

Working: All the 3D printers’ posses fivebasic process functions for creating a three-dimensional model.

First - The Print Surface is fed with a unique powder.

Second - The powder is spread on print surface by a rollerat a preset depth. This process takes just a few seconds for its completion.

Third - Color is applied to the powder’s initial layer bythe Standard Inkjet Print Heads.

Fourth - The solidification of powdered layer takes place.

Fifth - The lowering of print surface for powder’s anotherlayer is enabled.

This process goes on repeating till the completion of thewhole 3D model occurs. The mixture of Ink Jet Color and powder results information of a bond. The solidification occurs this way. So, if no printing iscarried out at the specified layer or location, the powder retains its state,i.e. it does not get solidified. Once the printing process comes to a halt, thepowder gets blown out, thereby leaving the output which is the reflection ofthe original model or drawing. Depending on complexity and size of output, thisprocess takes around ? an hour. These 3D printers do a commendable job,especially when pre-production examples or working prototypes of the specifiedobjects are seen on the computer monitor.

Self-replicating 3D printers: The‘self-replicating rapid prototype’, better known as RepRap is believed tolessen the price of three-dimensional printers, thereby paving way for thefuture where spare parts and broken objects are just re-printed on a homelybasis. There would also be a way out for creation of unique and novel objects.

At present, 3D printers of the above type cost around$25000. They are still to capture the domestic market. They are instead beingused by the industry for developing parts for machines like aircraft engines,hearing aids, and spaceships.

Plummeting Prices: Adrian Bowyer has stronglybelieved the prices of self-replicating 3D printers to lower to around $500, asno cost other than that of raw materials would be involved. He has furtherstated that these machines would turn out to be more competent and build up newcapabilities. Once the soft ware guiding the process of self-replicationbecomes available, it would be there at the free service of the customers. Thishas also been said by Adrian Bowyer.

Tepid Metal: Circuits are normally built by 3Dprinters by carrying out the fusion of powdered metal and laser. However, theself-replicating 3D printers are aimed at use of metallic alloy of cadmium,tin, leadFree Web Content, and bismuth that have a low-melting point and squirting them to havethe circuits formed from a syringe that is thoroughly heated. It’s notcompulsory for the machine to be capable to assemble itself. Just production ofall those parts that are very necessary excluding the lubricating grease andmicroprocessors is required.
