According to a recent survey published in the 2018 edition of Sculpteo’s The State of 3D printing, those surveyed are using this technology to:
–Accelerate product development (39%). (In 2017, this figure was 28%, yet still the number one reason for using 3D printing.)
–Offer custom products and limited series (25%) of products. (In 2017, this figure was 16%.)
–Increase production flexibility (19%). (In 2017, this figure was 13%. )

Of course there are other reasons engineers use 3D printing/additive manufacturing. This technology is the best technology to use to create objects with complex geometries, parts with cooling channels, and it makes custom, one-of-a-kind parts affordable to make.
The 3D printer is very important in the technical fields such as for engineers which helps to design things in a proper way. The given information is about how engineers using 3D printing is really very interesting.
