#1 SAVE MONEY
Your 3D printer can pay for itself by printing things that you might ordinarily buy. You can create almost everything from smartphone cases to paper towel holders, reducing household expenses while adding a personal customized touch to your home. You can print practically any every-day object including shower curtain rings and safety razors.
However, to be able to produce replacement parts and customized items you will have to use 3D modeling software. If you are new to 3D design you will have to learn how to use the software to design the items you would like to print. Numerous STL files of 3D models can be found online, but to print replacement parts for everyday objects, you will have to design them yourself.
#2 FUN TO PLAY WITH
3D printing can become your hobby. With a 3D printer, you can create various fun objects or little works of art. Design your own unique items and display them in your home or give them to friends and family.
As you experiment and have fun with the 3D printer, keep in mind that it is not a toy but a serious tool. 3D printing is not as simple as it sounds, in fact, it can be very complicated. You will need to learn how the technology works so that you can handle any issues that might occur. For example, the nozzle can get clogged and you will need to know how to unclog it to put the printer back to work.
#3 THE TECHNOLOGY OF THE FUTURE
Buying a 3D printer and learning how to make the best of it will prevent you from falling behind. It will enable you to be a part of this new revolution.
Learning how to design and print in 3D is a good way to prepare yourself and your family for the future. As the 3D printing technology evolves, you can expect to see doctors printing replacement organs and limbs. Meanwhile, builders and manufacturers will adopt 3D printing to their fields.
#4 POTNTIAL SOURCE OF INCOME
You can earn money by processing 3D print jobs for people who place online orders. Spend some time developing your printing skills and then enroll in an online printing service such as 3Dhubs to gain instant access to profitable print jobs. Your 3D printer also gives you a chance to create and sell designs or products or start teaching 3D printing classes.
You should keep in mind that, even though the prices of 3D printers have come down significantly, producing high-quality items will require you to buy a more expensive 3D printer.
Also, you should consider the time and the effort that it would take to design the items, print them and, if necessary, post-process them. Then see whether you could actually profit from selling customized 3D items.
