Lots of people are trying to develop cheap 3D printers for people to use at home.<ref>{{Cite web|url=https://www.techradar.com/news/best-3d-printer|title=Best 3D printers of 2019|last1=Printers|first1=Matt Hanson 2019-11-19T19:43:25Z|last2=scanners|website=TechRadar|language=en|access-date=November 20, 2019}}</ref> Libraries have also started to buy smaller 3D printers so that people can learn about them without having to buy one. Lots of work has been done by [[Do it yourself|DIY]] communities, as well as schools and [[Hacker (hobbyist)|hacker]] communities. By 2017, more people were starting to use 3D printing in their own home for small items such as [[gear]]s and small decorations.<ref>{{Cite web|url=http://lj.libraryjournal.com/2015/03/technology/umass-amherst-library-opens-3d-printing-innovation-center/|title=UMass Amherst Library Opens 3-D Printing Innovation Center|date=April 2, 2015|archive-url=https://web.archive.org/web/20150402221847/http://lj.libraryjournal.com/2015/03/technology/umass-amherst-library-opens-3d-printing-innovation-center/|access-date=November 13, 2019|archive-date=2015-04-02}}</ref><ref>{{Cite web|url=https://travelinlibrarian.info/2015/01/map-3d-printers-libraries/|title=A Map of 3D Printers in Libraries|last=Sauers|first=Michael|date=January 12, 2015|website=The Travelin' Librarian|language=en-US|access-date=November 17, 2019}}</ref>[[File:3-D Printed Spinal Disc (5165) (18306277429).jpg|thumb|300x300px|3D printed spinal disc]]

3D printing is used to make medical supplies cheaply. People think that the two biggest uses will be making hearing aids and false teeth <ref>{{Cite journal|last1=Corsini|first1=Lucia|last2=Aranda-Jan|first2=C.

== Guns ==

In 2012, [[Defense Distributed]] uploaded files to the internet for a [[:en:3D_printed_firearm|3D printed gun]] "that could be downloaded and reproduced by anybody with a 3D printer". After Defense Distributed released their plans, people were worried that they may cause problems with [[gun control]]{{cn}} A year later, in May 2013, the [[U.S. state|US State]] Department asked [[Defense Distributed]] to take down the plans, which they did.<ref>{{Cite web|url=https://www.theatlantic.com/national/archive/2013/05/state-department-defense-distributed-3d-printed-gun-plans/315405/|title=State Department Asks Defense Distributed to Take Down Its 3D-Printed Gun Plans|last=Bump|first=Philip|date=May 9, 2013|website=The Atlantic|language=en-US|access-date=November 22, 2019}}</ref>

== 3D Printing Noise ==

−

3d printers do produce noise as its operation involves a lot of vibration. The University of Michigan<ref>{{Cite web|title=Harmful Noise Levels {{!}} Michigan Medicine|url=https://www.uofmhealth.org/health-library/tf4173#:~:text=A%20sound%27s%20loudness%20is%20measured,concert%20is%20about%20120%20dB.|access-date=2022-07-17|website=www.uofmhealth.org}}</ref> shown how much sound does a 3d printer may produce. Their research shows that sounds more than 85 DB is harmful for human. However, the good 3d printers with silent [[motherboard]] may limit the noise up to 55 DB. Still there are plenty of manufacturers who could not even identify the best way of reducing 3D printer's noise. But, there are some techniques that can help you to identify the quiet 3d printers<ref>{{Cite web|last=Heer_Alina|date=2022-06-29|title=What makes a 3D Printer Noisy|url=https://www.digthisout.com/best-quiet-3d-printer/|access-date=2022-07-17|website=Dig This Out|language=en-US}}</ref> and prepare yourself to reduce the noise at a substantial level.

There are plenty of things to consider such as fan size and its rotation, stepper motor and the stepper drivers' performance etc. However, the noise may also arise due to dust clogged in the extruder or lack of maintenance.

Who knows? Maybe they'll install 3D printers on the next Mars Rover to make a case as it falls, or even fix itself! Maybe you will design the blueprint for this!<ref>{{Cite web|last=MYNT3D|title=The Best 3D Pens For Artists and Creators|url=https://www.mynt3d.com/|access-date=2025-11-06|website=MYNT3D|language=en}}</ref> Mynt3d pens are a good place to start with 3D printing.
