3d Printing Rapid Prototyping

View:

With modernization, a rapid growth of newer technologies is capturing all the aspects of human life. Starting from food and things of daily uses to vehicles and introduction of various technologies like the computers and related mechanical transformations of the communication medium ? the trajectory of modern life is speeding upwards, with us needing to keep pace with it.

As everywhere, there has been a rapid growth in printing technology as well. Printing has developed over the ages to what has now been called the 3-dimensional printing. Printing has come out of its age-old forms and has introduced new technologies for innovations in the field.

While discussing the 3D printing technologies that are introduced in the present period, certain aspects related to printing need to be addressed. They are - i) three dimensional printing and 3-d printers, ii) other type of rapid prototyping technologies, for stereolithography, selective laser sintering and the fused deposition modeling; lastly, and, iii) rapid protective engineering and development.

There are various projects undertaken by different companies or groups that have brought about revolutionary changes in the printing technology. They have been briefly discussed here.

?RepRap 3D printing quality development: The RepRap is the project that developed the 3D printing technology and went on a step further to develop the technology chronologically. They presented the photographs of door handles that are taken at different times with different printing technologies. The photographs showed marked difference in the printing texture and dimension of the print out.

?In the 2007 Extreme Redesign Contest, the challenge was on the 3D dimension printing where there were various people who presented their designed models for example the 3D Brain Lamp. There were also many students who created their own 3D design under the contest named Extreme Redesign. The students presented various types of 3D printed models like the Rubix Cube for the blinds and the design of a Solar-Powered Water Desalination Unit.

?The Nanofactory 3D printing technologies are introduced that are related to the nanotechnologies. Nanofactory is actually the ultimate expression of the versatile potential of the nanotechnology. Thus, by tapping the nanotechnology, the experts have developed a 3D printing technology that is known for its precision and fine quality.

?The 3D Systems Corporation, which is a leading provider of 3D images and models, has introduced a Rapid Prototyping and Manufacturing solutions. The company announced that the new V-Flash Desktop Modeler that they created newly for the revolutionary 3D printing is just the perfect for the high quality printouts having three-dimensional feel. The new product is capable of building three-dimensional printing within a short notice and is helpful to a large number of people belonging to different professions. It helps the designers, students, hobbyists and engineers to print their imagination on paper and design and build up their ideas on desks.

There are many 3D printers in the market that are made such that the users are easy on the usability of the printers and the manufacturers must make sure that the proceedings are easier and the users are comfortable and familiar with the basic factors of the 3D printing.

3d Printing Rapid Prototyping

Rapid Prototyping can be defined as the process of constructing physical objects automatically by making use of ‘solid freeform fabrication'. The initial techniques regarding prototyping came into being in late 1980s. They were then used for producing prototype parts and models. In today's world, they are being used for much wider applications. For instance- manufacture of quality parts. This technology is used by certain sculptors for producing complex shapes in order to display them in ‘fine arts exhibitions'.

Origin: Rapid prototyping has taken virtual designs through ‘animation modeling software' or ‘computer aided design (CAD)'. Thereafter, transformation into virtual, thin, horizontal cross-sections takes place. Each cross-section then gets created in the physical space. This process goes on till the model gets completed. It is better known as WYSIWYG process. Let's understand this process in detail.

WYSIWYG: WYSIWYG as the abbreviation for ‘What You See Is What You Get'. It is used in ‘computing' for describing a system wherein content looks similar to final product at the time of editing. It is generally used in word processors. However, this use is in the form of HTML (Web) authoring. The popularization of this phrase was carried out by the comedian ‘Flip Wilson'. His character ‘Geraldine' used to say this very often to give an excuse against her idiosyncratic behavior.

This expression came to be applied later to computer-based applications as practicality in technology arrived. At times, it is phonetically spelt as ‘Wizzywig' or ‘Wizywig'. It has also been used as a brand name for a ‘lighting design tool' utilized in theatre industry to pre-visualize the shows and 3D CAD.

The process further : The additional fabrication causes the machine to read data from CAD drawing. After that, consecutive layers of powder, sheet material, or liquid are laid down. Likewise, a model gets built-up from a chain of cross-sections. Such layers, corresponding to CAD model's virtual cross section, are then fused automatically or joined together for creating the ultimate shape. The basic advantage of additive fabrication goes to state that any geometric feature or shape can be created through this.

The CAD software and machines are interfaced by the ‘standard data interface' in the ‘STL file format'. The function of STL file is approximating the shape of an assembly or a part by making use of triangular facets. Surfaces of higher quality are produced by smaller facets.

The word ‘rapid' can be used relatively. The construction of models using present-day methods could take time ranging from a few hours to a few days. This depends on the technique used, along with the complexity and size of the model. The additive systems take less time. They can produce models within some hours. Some techniques such as ‘solid freedom fabrication' make use of two materials for construction of parts. The 1st material is known as ‘part material' and the 2nd one as ‘support material'. The removal of support material takes place by heat. It might also be dissolved with water or any other solvent. When it comes to manufacture of plastic products, that too in large quantities, injection molding proves to be a cheaper alternative.
