2. 3D Printers have dropped a lot in price

This would be the second advantage of buying a 3D printer in these times.

The truth is that they have dropped a lot of prices.

Believe it or not, by mid-1986 Charles Hull developed a 3D printer that used SLA technology, it had a cost that was around $ 300,000USD for that time.

Today you can get a small 3D printer for just under $ 300USD. In other words, it has become a much more accessible technology.

3. N3D printers are much easier to use

This is the third advantage of acquiring a 3D printer.

At the moment there is already a good variety of software for 3D printing, both paid and free, and for different technologies such as FDM and SLA.

It is just a matter of finding which one you like the most and which one best suit your needs.

4. There is a large community of people with 3D printers

We want to emphasize that currently there is a large and extensive community of users who have 3D printers, many of them call themselves Makers.

What’s interesting about this is that you will find many forums, video tutorials, web pages and endless content that you can access to learn about this technology and improve your 3D prints. This is something extremely valuable and outstanding because now there is a kind of collective intelligence.

Find in this link a great list of 3D communities.

5. 3D print parts that are broken

Has it happened to you that you broke a part of an object or device that you liked, and either you do not get the part because it’s not sold anymore, or there is simply no stock of the part in your country, and bring it from another country would be more expensive than expected.

Well, you can 3D print that broken piece, thus saving the device you did not want to lose.
