3D Printers
By: Nick Butzow
Intro to 3D Printers
Early History
First method created by Charles Hull in 1986
Method consisted of a UV light hardening liquid resin
Method was patented under the name stereolithography in 1986
It caused others to create new methods of 3D printing that we have today
About Charles Hull
Born May 12th, 1939 in Clifton, Colorado
Went to University of Colorado and got a B.S. in Engineering Physics
Worked at a UV light manufacturer where he got the idea to use UV light and liquid resin to create 3D objects
Founded the company 3D Systems in 1986
Also co-created the STL file format that is used today for 3D printing with CAD

Educational/Prototype Uses
3D Printing and Engineering
Patented by Charles Hull in 1986
Consists of UV laser flashed on liquid photopolymer resin
UV laser causes resin to harden
New liquid is layered over top the hardened resin and then hardened
After many layers 3D figure is created
Technology that allows 3D objects to be created through various methods
Professionally known as addative manufacturing
Changed how manufacturers create and prototype products
Invented in the late 80's and early 90's
Become very popular in recent years
Many different uses from desktop to industrial to business
Intro to 3D Printers 2

Many different uses from desktop to industrial to business
History of 3D Systems
Founded by Charles Hull in 1986
Commercialized SLS in 1992
Hull is the current CTO and Avi Reichental became the current CEO in 2003
Started acquiring various small 3D printing companies in 2002
Will.I.Am became the Chief Creative Officer of 3D systems in 2014
There are four main types of 3D printing that are used comercially and and in households.
Stereolithography(SLA)
Fused Deposition Modeling(FDM)
Selective Laser Sintering(SLS)
Selective Laser Melting(SLM)
Created in the late 1980's by S. Scott Crump
Consists of a filament being heated and then laid on a surface layer by layer until it creates 3D figure
Filament is usually made of plastic or rubber
Most recognizable form of 3D printing
Commonly used in home 3D printers

Patented by Dr. Carl Deckard in the mid 1980's
Laser is flashed on powdered resin that is near boiling point and powder hardens
Very similar to stereolithography
Mainly used for rapid prototyping and small scale production
Can create very complicated figures and shapes
The overall most popular 3D printing company is 3D Systems
They create moderately priced 3D printers for consumers and businesses alike
Another popular brand of 3D printing is Stratsys
They were created in by S. Scott Crump in 1989
Stratasys owns the patent for fused deposition modeling and is most well known for their FDM printers.
Stratasys owns many companies such as MakerBot and SolidScape
Many different uses
Historically 3D printing is an industrial technology
Recently has become more common for businesses and regular people
Very useful for prototyping
3D printing is very important to automotive industry
Used to create prototypes for new car parts
Can even be used to create fully functioning cars
Manufacturing industries use 3D printing to create products quicker and more efficiently
Desktop printers can create anything you need around the house or office
Create replacement boxes/containers, utensils, home goods, etc.
Also used to personalize whatever objects you need around the house with different colors/ designs
MakerBot is an example of a home 3D printer
3D printing has been revolutionary for the dental and surgical industry
Bio printing is a type of 3D printing can be used to create artificial human parts
Bio printers can create bones or tissues on site at hospitals
Dentists can use 3D printers to make precise replacements and retainers
Used in schools and universities to teach students about designing
Used in projects for schools
Also teaches about CAD
Very useful in prototyping
Makes it much easier and quicker for people to bring new ideas to life
3D Printing and Engineering 2
3D printing and engineering have a very strong connection between each other. Because of the ability to precisely create whatever you want out of plastic, 3D printing is very popular among engineers for making prototypes.
Sports engineers at clothing companies are using 3D printers to design and test new types of shoes and equipment
One example is the Vapor HyperAgility football cleats
They were created using a SLS 3D printer
The cleats' 3D printed design allow the players to be quicker and more agile

Future of 3D Printing
Examples of future 3D printing improvements
Faster 3D printing
Printing of fully functional organs/body parts
Printing with multiple materials in the same object
Another future 3D printing techonology is 4D printing that produces materials that can change physical properties based on temperature, pressure, moisture, etc.

Major Past Events
3D printing works using 5 main methods
Most involve using a laser to solidify material layer after layer
Some methods use melted filament instead of powder
Most 3D printing designs are created using CAD and STL files
3D scanners can be used to scan 3D objects and print them again
Stands for Computer Aided Design
CAD is the use of computers to create or modify 2D and 3D designs
People create designs of objects to be 3D printed and then the file is converted to STL file

Stereolithography starts with liquid resin being poured into a vat
A UV laser is then flashed on the liquid causing it to harden
New layer of liquid is brushed over top and process is repeated
Each layer is from .05 to .15 mm thick, so process takes a long time
Starts with filament being melting in nozzle
Melted filament is then pushed through nozzle creating a line of resin on a base in the form of a shape
Layers of resin are stacked forming a 3D figure
Filament is usually made of plastic or rubber
Selective laser sintering consists of a laser fusing powdered material into a shape
New powder is brushed over fused shape and new layer is fused over top
Process repeats until object is made
Selective laser melting uses the same process but the material is fully melted not just fused
1992- First SLA 3D printer created
2002- First working 3D printed animal kidney created
