Fast Pace Prototyping Services

Rapid prototyping, otherwise known as desktop manufacturing, additive fabrication, solid freeform fabrication, three dimensional printing or layered manufacturing, has always been in the forefront of development and design. 

By quickly creating prototypes that are similar to form and function as the actual production unit, developers are able to create a product that meets the expectations of consumers and project sponsors. 

Through a combination of rapid prototyping methods and traditional model making, high quality prototypes can be created with less the expense and quicker turnaround times. 

Compared to traditional fabrication methods like milling and turning, rapid prototyping is way better in terms of accuracy, speed and quality. By using rapid prototyping techniques complex and intricate shapes can be formed without any complicated machine setup, prototypes can be created from different types of materials or composites, and the process simplifies the whole process of creating a prototype. 

Because of the advantage it brings, rapid prototyping services are being offered by companies to engineers and system developers to better understand their product and communicate better with their target clientele. Not only does the technique used by designers, developers and manufacturers, but professions like surgeons, architects, artists and even mere individuals regularly utilize the technology.

Among the services being offered are stereolithography, selective laser sintering or SLS, fused deposition modeling of FDM, laminated object manufacturing or LOM, inkjet-based systems and three dimensional printing or 3DP. 

SLS is one of the most used tools in rapid prototyping techniques. In SLS rapid prototyping, a CO2 laser is used to melt powdered thermoplastic materials to create layers. A scanner guides the laser and melts specific areas and materials based on the information fed by the 3D CAD. 

Prototypes created from SLS processes are strong and more tolerant to stress. Materials used in the market include DuraForm, CastForm, Somos 201, FR85A and LaserForm. Most of the prototypes created from these materials are usually ready to be used and only require minimal clean up and finishing. 

Stereolithography or SLA creates prototype part layers through the use of a solid-state laser. The 3D CAD data guides the laser as it cuts through the surface of a container which normally contains liquid photopolymer material. 

In LOM, on the other hand, uses a paper sheet with one side laminated with adhesive. The laser cuts the outline on the paper sheet. This process does not involve any chemical reaction which makes it cheaper and large parts can be made.

Characteristics Of Self Publishing

Before the boom of the internet world, the traditional publishers are the kings of the publishing world but now, there the Cafepress, Lulu, Createspace and others that will help you to publish your book online.   The main characteristic of the boom of Self Publishing industry like Lulu is because of the traditional publisher’s absence in the circulation.  Some of the traditional publishers will answer you, that they don’t have enough budget to print your book, even if they had because of just a simple answer “manuscript rejection”.   Compare to the self publishing that you are the editor of your own book.   There are different online publishers including the three companies mentioned earlier to produce your book as well as print them and ship them then distribute it, after that, they make profit from your writing.  Self-publishers are not that the type of publishers that will actually paid the writings but the author himself will p...

Do You Need a Wheelchair Lift?

Are you a person stuck in a wheelchair who wants to have greater mobility? Are you a caregiver who wants to make your work easier? Then maybe you should consider getting a wheelchair lift.  Wheelchair lifts are increasingly becoming popular. This is mainly because they can really increase the mobility of handicap individuals. Wheelchair lifts are definitely advisable for people who have difficulty moving around in different places.  Another great thing about wheelchair nowadays is that they come at a reasonable cost, believe it or not. So there really is no reason not to get wheelchair lifts.  Wheelchair lifts come in different types. Each type has a different use. The two most common types of wheelchair lifts are the stair wheelchair lift and the automobile lift.  As the name suggests, home stair lift are designed to help disabled people go up and down stairs. This type of wheelchair lift is very popular probably because of it s very practical fu...
