3D printing technology uses digital model files (or CAD files) to create real-world objects. The machine uses powdered metal or plastic to print an object layer by layer. An advantage of using this technology is that irrespective of the object’s design and complexity, the printer prints the complete model within hours. It saves time and improves flexibility as compared to the traditional manufacturing process. Therefore keeping this in mind, PCBWay has introduced its Online rapid prototyping manufacturing supply for 3D printed parts. Read more about PCBWay‘s rapid prototyping services here.
3D printing technologies
Based on the product design and applications, there are various ways to print an object. But the initial process of all these technologies is the same. After the 3D model gets uploaded, the model is sliced into numerous thin layers using the printer software. Thus, converting a 3D object into 2D layers. The set of instructions collectively make a G-code. Now according to the working principle of the printer, the printing can be either of the following three types:
FDM (Fused Deposition Modeling)
It is a cost-effective way to print the desired thermoplastic part or its prototypes. The process involves heating a filament to the desired temperature. A motor then prints the melted filament, layer by layer. After finishing one layer, the platform moves down and continues the process till the object is ready.
SLS (Selective Laser Sintering)
This method is ideal for designs with complex structures. It uses a CO2 laser to scan a layer of polymer powder. After scanning one particular layer, the temperature of the powder rises. And the selective particles bind together. The platform moves down and continues the process layer by layer to print the complete object.
SLA (Stereo Lithography Apparatus)
SLA is best for applications with high dimensional accuracy. It uses a UV (Ultra-violet) laser to scan a liquid photosensitive resin. The resin solidifies after getting exposed to UV light. After completing one layer, the workbench lowers and cures the next layer. The process repeats till the 3D object is complete.

And select the printing material you wish to print your object. Apart from the standard printing materials, PCBWay offers print material of your choice. Just choose “Custom” in the material section and submit for an expert review of your design. Based on your shipping method, the order you placed will be at your place at the right time.
Advantages of 3D printing
Flexibility in designing
The 3D printing technology allows you to craft complicated designs that are difficult to fabricate via the traditional manufacturing process. And that too at no extra cost.
The process involves fabricating an object in a single step. The highly advanced printers do not require manual operators to be present there all the time, so there is little or no wastage of the printing material. As a result, the overall price of the printed object reduces.
The highly advanced printers are capable of fabricating an object within hours. Even the most complicated designs are easy to print with a 3D printer. It reduces the time to complete a product thus, accelerating the service.
