Time and Cost reduction using Rapid Prototyping (RP)

�ۿ۴�ý — Mon, 19 Jan 2015 14:21:12 +0000

With the advancement in technology, we have come across multiple strategies to enhance new product development. Rapid prototyping has been one such method that has evolved to provide considerable reduction in time and costs. is defined as the process to transform a product or component, taken from a CAD modeling software and changed into a physical part for the purpose of implementation. It is also capable of producing the part to any complex geometry shape in a short time compared to manufacturing approach.

Why should we do Rapid Prototyping?

To assemble the entire parts and its sub-assemblies
To feel the aesthetic and working of the product at earlier stage
To gauge a replica of actual part
To detect design issues before manufacturing
To reduce development cost
To provide high quality in reduced timeframe
To avoid critical technical hazards
To increase the efficiency of the newly manufactured devices
Rapid prototyping enables manufacturer or mechanic to do the fast configuration.
Designers/manufacturers must have sufficient time for doing good calculation to cut expenses in manufacturing the electronic components.
Product manufacturing cost is reduced
Rapid prototyping or RP model enhances the perfection in device configuration
It is easy to keep the natural aesthete of the device by crafting a replica or rapid prototyping model.

Rapid Prototyping Reduces the Manufacturing Cost

Rapid prototyping system manages the manufacturing cost. If you have a complete preset design of a specific model, you must be able to do the quick estimation to avoid unnecessary expenses. You can also place this computerized prototype model to a group of product quality analyzers to do the proper analysis without lowering down the overall quality.

What is Rapid Prototype technology?

There are mainly three different types of Rapid Prototype system based on the material form:

Liquid based RP system: The material will be in liquid state, by a curing process the material gets converted to a solid state. E.g. the system includes stereo lithography (SLA).

Solid based RP systems: The material will be in solid state, in this the success layers of material are laid with the control of computer and can generate any complex geometry shapes. E.g. the system includes Fused Deposition Modeling (FDM).

Powder based RP system: The initial form of the material is in the powder form and creates a geometry adding material in successive layers. E.g. the system includes Selective Laser Sintering (SLS).

What are the Materials Used in 3D Printers?

There are many different materials can be used in to name few are ABS Plastic, Polyamide (Nylon), PLA, Poly carbonate and so on.

What is the Application of rapid prototyping?

From the concept design to functional prototype, the prototype can be used in various industries like Aerospace, Automotive, Consumer, Industrial and medical. The design can be transformed to manufacturing process for casting, patterns and mold parts to produce plastic or metal parts with precision options.

Reduce Unnecessary Technical Features of the Device

Engineers have good scope to remodel or design the new device step by step. They do different practical demos to see actual effectiveness of a device. So, ultimately, the overall result is favorable to a mechanic or designer. He removes unnecessary tech features to make the device much more workable with growing efficiency.

In a nutshell, the intent and purpose of the product can be communicated effectively to user using Rapid Prototyping. It also demonstrates the product with fit and functionality without going for expensive tool making. Additionally it eliminates or reduces any unnecessary features at the early stage, hence positively influencing time and cost parameters.

CAD – Popularly Beneficial

Computer Aided Design, popularly known as CAD Design, refers to the use of computer technology for the purpose of designing and drafting in various fields. It is also known as Computer Aided Design and Drafting (CADD). CAD is extensively used in many fields, as a substitute for manual technical and engineering drawings. It is widely applicable in industries such as architecture, aerospace, multimedia, automotive, prosthetics, etc. The major benefit of Computer Aided Designs over the manual drawings is that the designers can complete the designs much faster. As a result, their productivity increases and more works can be completed in less time. The firms benefit much from this as they can finish more work with less labour.

The designs done using are of high quality and fewer errors are likely to occur when compared to manual drawing. If errors occur, they can easily be corrected and the design can be modified using the computer technology. Moreover, the design can be zoomed in and out for obtaining distinct views of the parts or components of the drawn object. With the CAD software, the designer can scale the image as per the needs and guidelines. In case the designer wants to add additional properties to an object, the Computer Aided Design software provides the option to create such custom properties.

The computer hard drive saves the data drafted with CAD. Hence, the backup is automatically created, which reduces the risk of losing the data. Furthermore, an easy conversion of 2D drawings into 3D is also possible with the use of CAD technology.

Advances in Laser Scanning and 3D CAD Visualization

We at �ۿ۴�ý Technologies offer a range of CAD CAM CAE services, using the latest cutting-edge technology. An ambitious heritage project in Scotland is undertaking a 10 year project to digitally scan 500 UNESCO world heritage sites. Using the latest 3D CAD visualization techniques and system hardware has created the most detailed historical data files ever recorded. Laser scanning is the fastest and most precise method there is for capturing complex 3D images. Urban landscapes, geological features and heritage sites are just some of the applications. Scanning from 0.5 to 300 metres, with a data capture speed of 50,000 points per second is possible, at extremely high levels of resolution. The system software allows point clouds to be integrated into other data sets such as photographs, thermal images etc, and even 2D to 3D conversion of archive images. The hardware design for a portable laser scanner needs to be robust, light and compact, and able to survive field exercises without damaging the embedded firmware. In the field, the beam is ‘tuned in’ to the object being scanned, usually from a static position on the ground, or an aircraft (when it’s called LiDAR, short for Light Detection And Ranging). As the surface is scanned, the laser light being returned is analyzed by the system software, which calculates the distance of the beam to the surface of each point. The millions of points are then computed into a point cloud. Complex 3D objects must be scanned from several angles to ensure as much detail as possible is included. CAD visualization by laser has many applications, from reverse engineering to making National Geographic documentaries.
