The 3D Printer or rapid prototyping system is a computer assisted manufacturing process where software guides the creation of three dimensional models. In the past model makers had to rely on plastic formers or metal modeling techniques to create replicas, reproductions and prototypes. But now because of the more advanced technologies that have been developed in the area of prototyping a new process known as rapid prototyping manufacturing is available. The 3D printer technology available today allows the hobbyist to create custom designed 3 dimension models simply and easily in the comfort of their own workshop. Long and timely manufacturing processes have been eliminated by the 3D printer and at a reasonable price for the hobbyist.

3D Printer Technology and Model Creation

Traditional modeling techniques available to the hobbyist involved a long list of design steps and an even longer list of manufacturing steps. Imagine having a 3D printer that could reproduce from a computer assisted design (CAD) file a rare model train to add to your collection. The 3D printer would build the model train from the ground up with all the features of the original including the lettering and the correct color of paint. Using liquid polymers extruded from injectors the 3D printer would craft a replica of the train that would be indistinguishable from the original design. By building the train layer upon layer the 3D printer software would calculate the proper length, width and height requirements from the specifications and the rapid prototyping process would produce a completed 3 dimensional model of the train. The 3D printer technology would enhance any hobbyist’s abilities and creativity.

3D Printer Advantages for Model Reproduction

The computer assisted design advantages of the 3D printer are numerous compared to traditional prototyping techniques. Traditional techniques that employed plastic formers to create models required large, bulky and sophisticated equipment which also required a major investment to own and operate. 3D printers however are reasonably sized, compact and much less expensive to own and operate. The set up time and ease of operation has made the 3D printer a popular choice for creating models and replicas. The almost unlimited flexibility and potential applications for the hobbyist to create models with the 3D printer is a distinct advantage of this technology.

Traditional modeling techniques carried some dangers inherent in the process. Some techniques involved hot metals being poured into molds while others heated toxic chemicals which were pressurized and cooled. The technology used in the 3D printer produces no toxic chemicals to harm the hobbyist nor uses any toxins during the prototyping process.

With metal modeling techniques a substantial amount of post production cleanup of the models and work area was needed. With the 3D printer an additional advantage is gained from using the rapid prototyping technology as post production work is drastically reduced. The advantages of the 3D printer for the hobbyist are many including creative flexibility, safety and ease of operation. The innovative designs that the hobbyist will be able to utilize with the 3D printer present a distinct advantage over traditional model and replica processing methods.

3D printing also known as rapid prototyping technology is the design process where computer programming guides the creation of a three dimensional model through the layering of fabrication material. Engineers, designers and technicians would benefit from advanced prototype production. Recently new technologies have been developed producing many advantages for those needing rapid prototype technology. The 3D printers available today are faster, easier and more affordable than previous fabrication technologies. 3D printing has also eliminated the need for expensive tools and skilled craftsmen to produce design prototypes, making the process more affordable, cost efficient and desirable.

3D Printer Technology

The 3D printers technology is quite simple to understand really; computer assisted design software (CAD) directs an inkjet nozzle to extrude small amounts of material in layers to form a three dimensional model. Almost like building a sand castle at the beach. By adding layer upon layer the CAD software is able to calculate length, width and height requirements from design specifications and guide the process toward completion of a 3 dimensional model. Traditional prototypes were built from solid blocks of material and the excess was cut away until the model was produced but with today’s technology the models are built from the ground up with no excess. Of course the sophistication of designs and materials used will impact the time required to produce individual 3D prototypes.

Individual 3D printing needs will differ and so the materials used in prototyping will differ also. In rapid prototyping the materials used can range from plasters, resins and advanced polymers. The choice of design material depends on the required durability, lifespan or sophistication level of the model to be fabricated. Fused deposition modeling techniques use liquid polymers from injectors to create models. In this process the 3D Printer injects photopolymers layer by layer on to a base platform and then the materials are cured with ultraviolet light. Inkjet printing techniques differ as they use granular substances such as plaster, powder or corn starch and combine the materials with an adhesive which bonds the model together to produce a 3D prototype.

3D Printer Advantages

The new technology of 3D printing produces advantages in the areas of speed, cost, and simplicity. Engineers and design technicians can use 3D printing during the conceptual stages of design. A rapid prototype enhances the design process by providing a 3 dimensional model of the design. Having an actual model to see and manipulate during various stages of the design process can help designers and engineers to facilitate prototype corrections, enhancements and project completion.

Also, unlike some prototyping techniques the 3D printing advantage produces no toxic chemicals from the process nor uses any toxins during the process. An additional advantage gained from using rapid prototyping technology is post production work is minimal, only the removal of excess materials produced during the printing process is necessary. The advantages of 3D printing are many including reduced costs, efficiency and safety. As new innovations in 3D printing technology become available so will additional advantages.

Rapid prototyping, otherwise known as desktop manufacturing, addition fabrication, solid freeform fabrication, 3 dimensional printing or layered manufacturing, has always been in the forefront of development and design.

By quickly making prototypes that are similar to form and function as the particular production unit, developers may be able to create a product that meets the expectancies of shoppers and project sponsors.

Thru a mix of quick prototyping methods and standard model making, prime quality prototypes can be created with less the cost and faster turnaround times.

Compared to normal fabrication techniques like milling and turning, quick prototyping is way better in terms of accuracy, speed and quality. By employing fast prototyping systems complex and complex shapes can be formed without any sophisticated machine setup, prototypes can be created from different types of materials or composites, and the process simplifies the entire process of creating a prototype.

Due to 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 customers. Not only does the methodology utilized by designers, developers and makers, but professions like surgeons, designers, artists and even mere individuals regularly use 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 3 dimensional printing or 3DP.

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

Prototypes created from SLS processes are robust and more long suffering to stress. Materials used in the market include DuraForm, CastForm, Somos 201, FR85A and LaserForm. The majority of the prototypes created from these materials are sometimes prepared 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 thru the surface of a container which routinely 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 massive parts can be made.

3D printers are today creating a revolution in the rapid prototyping industry. Rapid prototyping technology (RPT) utilizes computer assisted design software incorporated into 3D printers which allow companies to create 3D Models during all phases of the product development process. The prototypes created by the 3D printers can then be used by marketing agencies to incorporate further enhancements and improvements into the designs. 3D printers used for rapid prototyping technology are able to produce models quicker, easier and more cost efficient then traditional model making techniques. The tremendous application potential for 3D printers and rapid prototyping technology is just beginning to be realized and will continue to play an important role in designing and creating 3D models for decades to come.

3D Printers used for 3D Models

The technology used in 3D printers for producing 3D models is computer assisted design (CAD) software which directs inkjet nozzles to deposit small amounts of fabrication material on to a platform in layers thereby producing a three dimensional model. Rapid prototyping technology has been used in various industries for over 10 years now. The cost efficiency of producing models for marketing agencies that need to make design changes quickly and easily based on focus group testing have found 3D printers an excellent solution for their rapid prototyping needs.

Marketing groups use sales demos and 3D models to solicit feedback from demographically selected groups before releasing a product on to the market. Based on the feedback the marketing agency receives from the focus groups design changes may be necessary. 3D printers are able to make the desired design changes and rapidly produce a new and improved model. With the new and improved 3D model in hand the marketing agency can obtain second level feedback from the focus group until they produce the most desirable 3D model possible. RPT is a method most suited for incorporating design changes and creating models in a very short period of time for market and sales research agencies engaged in product development.

3D Printers: The Advantages of 3D Models and Rapid Prototyping

3D printers bypass the costly and timely process inherent with traditional 3D model production techniques. Previous to rapid prototyping technology development most industries relied on traditional methods for producing models and prototypes. This meant using skilled craftspeople with very specialized tools to produce a single prototype or model. Many hours or days could be necessary to produce a single usable model. Employing skilled craftspeople for the task of producing models is an expensive proposition for any company. 3D printers assisted by CAD software produce 3D models for companies for a lot less expense and the turn around time is shorter as well.

With 3D printers there is no need to maintain workshops with specialized tools or to add the cost of skilled craftspeople to the bottom line of the company. 3D printers once up and running can provide the technology to produce models for a large number of industries in shorter periods of time and for less money. In today’s business climate in order for a product development company to advance and grow the capability to rapid change product designs in a cost efficient manner is crucial for continued success. 3D printers and rapid prototyping technology provides the answers for the company seeking more cost efficient and more timely 3D model and prototyping solutions.

Prototype and simulate data behaviour with Data masters

Data masters can be understood as lists of data fields. A data master is a single list, whose columns or attributes can be defined by the user. A very good example of this is a book store application. Imagine you need to create a prototype of an application to manage a book store, which needs to manage all the books. For that purpose, you would create a data master called Book, and add the attributes ISBN, Name, Author, Edition and Description. You would later use this data master to create screens with lists, creation and edition forms, etc.

Creating forms through Data masters

Drag and drop a data master from the pane to a screen or template to create a set of input fields with all the attributes of this data master in a form structure. Each field is linked to the data master’s attribute.

Drag and drop a single attribute of a data master to a screen or template to create a single input field linked to that data master’s attribute.

Add datagrids to your wireframes

Datagrid builds a list of data. In order to create a data grid for a particular data master, follow the steps:

Drag the data grid icon from the Screen Components pane and drop it in the canvas at the desired position. Use the size feedback to position the data grid to the desired location. Enter the data grid identifier and select the data master you want to list from the Data Master drop down. Once the data master is selected, all its attributes appear in the Data Field left list. Select the attributes you want to display in the data grid as columns.

Simulate datagrids with your own data

In the tab View and Edit Records you can add data instances of your data master. To do so, click on the plus button and add them manually. Also, you can import data from CSV files and export current data to CSV using the import and export utilities provided. When importing, the utility lets you select amongst three CSV separators: semicolon, comma and tabulator. Also, it lets you add the imported file records to the current or overwrite them.

i am doing research for my dissertation, which is on modernism but not sure what exactly yet!!
i am trying to figure out if designs made today following the same principles and materials etc as modernism can be called so.
modernism has been around since late 19th century, the materials and processes of modernist movement were new then, but are not today, they are old. does this not then make these traditional in today’s society?
if we are to have designs that follow the same principles as modernists then surely designers should be using new and innovative processes and materials from todays world, such as the rapid prototyping (stereolithography) techniques that are being continually developed.
can these be called modernist?
