3D printing is a process by which three-dimensional objects are created by joining or solidifying materials and combining them layer by layer, depending on the commands of a computer. 3D printing is becoming increasingly popular in many fields, this is why it is now commonly used by both professionals and amateurs.
There are many reasons why 3D printing is so widely used today. 3D printing costs are lower compared to other technologies and materials. No materials are wasted, and time is much more efficient. That’s why 3D printing is fast becoming the number one choice for many manufacturers and designers. In addition, human resource and labor costs can be significantly reduced with 3D printing.
We offer competitive 3D design and 3D printing services, architectural models and prototyping.
What materials can be used in 3D printing?
With the technological evolution of 3D printing, major manufacturers have begun to research and study various materials to expand the supply of raw materials that can be used in printing.
Thus, although the most popular material used at the moment is plastic (due to the low price and ease of use), many other materials such as metal, carbon fiber and more are beginning to take over the market.
Other more futuristic materials are being researched, and there are currently studies on 3D printing using food (there are cases of 3D printing of a pizza or chocolate dessert) or various organic materials in the medical industry, such as the bone.
There is a huge interest in this field; therefore, research and investment will continue, which means that 3D printing will try to grow and integrate even more in our lives.
The speed with which a 3D printer can produce models is a huge benefit in using this technology compared to old manufacturing methods. Therefore, 3D printing is much faster and easier than conventional manufacturing methods.
From the design stage to the final product, 3D printing quickly integrates ideas and models. Complicated projects can be taken from a CAD model and can be used for printing. It only takes a few hours to complete this process.
Applications of 3D printing
3D printing can be used to create numerous objects, both industrially and domestically. We will list some applications of this technology, as these only a small part that can be made with the help of 3D printing:
1. The automotive industry
The automotive industry has benefitted from this technology in recent decades, being among the first to use 3D printing in prototyping. No wonder that over time, the number of applications has increased, and is now being used to create parts in a faster and more personalized way than in the traditional way.
2. Jewelry making
Jewelry has always been loved because of its beauty and uniqueness, but it has been complicated to make, especially in the case of custom pieces. 3D printing is used successfully in this sector and it is a much easier way to create jewelry.
3. Customized parts
Both industry and home users or small businesses use 3D printing to create parts, which are probably much more expensive if they are purchased directly from the manufacturer or can no longer be found.
