3D printer is a device which can print physical 3D objects. 3D printers has left behind a generation of printers whose maximum capability was to print a given object on a piece of paper. A whole new dimension has been added to the printing technology – the 3rd dimension.
A 3D printer is a computer-aided manufacturing (CAM) device that creates three-dimensional objects. Like a traditional printer, a 3D printer receives digital data from a computer as input. However, instead of printing the outputon paper, a 3D printer builds a three-dimensional model out of a custom material.
3D printers use a process called additive manufacturing to form (or “print”) physical objects layer by layer until the model is complete. This is different than subtractive manufacturing, in which a machine reshapes or removes material from an existing mold. Since 3D printers create models from scratch, they are more efficient and produce less waste than subtractive manufacturing devices.
However ,the process of printing a 3D model varies depending on the material used to create the object. For example, when building a plastic model, a 3D printer may heat and fuse the layers of plastic together using a process called fused deposition modeling (FDM). When creating a metallic object, a 3D printer may use a process called direct metal laser sintering (DMLS). however, this method forms thin layers of metal from metallic powder using a high powered laser.
while , 3D printing has been possible since the 1980s, it has been primarily used for large scale industrial purposes. However, in recent years, 3D printers have become much cheaper and are now available to the consumer market. As the technology becomes more widespread, 3D printers may become a viable means for people to create their own home products and replacement parts.
The typical source content for a 3D printer is an STL file, it comes from two main sources, a new design modeled with 3D CAD software or 3D digital information captured from a real part using a 3D scanner.
Here at Javelin we tried an alternative method – convert a 2D photo into 3D printable material! To achieve this SolidWorks Certified Expert Dr. Irfan Zardadkhhan wrote a program in C++ that reads a PGM (Pixel Gray Map) file and translates the data into an X, Y, Z table. In the table, X and Y represent the location of the point and Z represents height, which equates to the gray intensity value of a pixel (when 0 is black and 255 is white).
once the XYZ file is generated as a plain ASCII file, using the scan to 3d solid works add in product the file is converted into a surface. Then Solid Works modelling tools are used to finish the 3D model data.
The model is then generated using a stratasys object 30 3d printer and the results are amazing. As you can see in images printed part contains a textured 3D face, depth of surface blocks provides detail; and when you hold the part in front of a light source the original picture will show through.
Avantages of 3d printer for photograph:-
Some of the modern 3D printers are capable of printing varied materials. These includes printing materials like brass, ceramic, steel etc.
Unlike, the early 3D printers with just one head, today’s 3D printers come with multiple heads. Each head is capable of giving one color to the object. With multiple head, it is noe possible to create more realistic 3D models.
Savings in long run:-
3D printing can provide savings in long run because, it avoids repeated designing costs.
With 3D printers, big corporations will no longer have to set huge manufacturing plants for product manufacturing. All they will have to do is print it out using one of the 3D printers.
latest printers have multiple printer beds. each bed will be used for printing one objects at time.
Future of 3D Printing:-
These printer capable of output in colour & multiple material.It will continue to improve to point where functional products will be able to output. effects on energy use, waste reduction, customization, product availability, medicine, art, construction and sciences, 3D printing will change manufacturing world .
If 3D printing is right tool for you, & we want to test out possibilities without purchasing a 3D printer – a 3D printing service might be the way to go.
Examples of services are: shapeways, ponoka &sculpteo.They can print object from digital file that we simply upload to our website. You can even sell your 3D designs on their websites and make a little money out of it.
Why it is famous for passport size photo:-
1. 3D printer are widely use now days for passport size photo because ,it gives attractive & glossy look to our photograph.
2. 3D printing allows ideas to develop our photo faster than ever.
3.It gives easy way to edit our photograph in latest technology .
4.In 3d printing the colors quality is good in photograph .
5.Through ,3d printer we can make digital photos to give real look to our photograph.
6.3D printer that prints the photograph in 600dpi.
7.Nowdays CAM( computer-aided manufacturing ) are most popular feature for editing a photograph in three dimensional image.
8. 3D printer gives 3d look to our photograph & picture quality is good.
This is all about 3d printing how it works on passport size photo.however ,3D printing give attractive & modern look to photograph.
