Transcript of 3d

Who created 3D printing?
Charles Hull
About him :
Grew up in rural Western Colorado
B.S in engineering physics
Moved to California; engineer at two places (worked on analytical equipment for chemists)
spent 10 years at DuPont’s Photo Products Division then worked at UVP Inc,California
Manufacturer of UV products
Developed an idea that led to 3D printing
What 3D printing is used for?
How 3D printing developed?
How much 3D printing costs?
How 3D printing makes existing technologies be better?
How it can contribute to our society?
1 .
Cost Effiency
with 3d printing, you can cut down your prototype cost as much as tenfold , you can actually chart down the amount of materials needed and thereby can determine the exact amount

Better Design
with 3d printing , you can design your products quicker and cheaper , and create multiple prototypes that you can easily modify as per your preference and convenience

Rapid Production
with industrial 3d printers being able to 'manufacture' almost any object within a few hours , the traditional time-consuming manufacturing methods are gradually becoming outdated.


Creation of new shapes and structures
additive manufacturing helps to produce as many complex figures as the human mind can conceive. from aerodynamic parts for space industry to jewelry and unique-shapes furnitures, the possibilities are unlimited
Replacements available 24/7
by using 3d printing you can just print the part you need right away


Home contruction is cheaper
reduce carbon footprint
more eco friendly
low cost homes
ex : in china , a company is already taking advantages of the technology to build low cost
homes with recycle material each costing about $5000

Prosthetics Become affordable
creating prosthetic that are cheaper than the convetional one , at under $100

Reprint Rather than wait for organ
3d printer can also be used to pile organic matter, systematically layer by layer to build tissue and organs.
* the technology is till in its infancy , but imagine the potential of this technology to saves life

Process of making a three dimensional solid figure from a digital file
What is 3D printing?
food industry
What 3D printing is used for?
Created by laying down successive layers of material until the entire object is created
Seen as thinly sliced horizontal cross-section of the soon to be object
How 3D printing developed?
First patent application for RP technology was filed by Dr Kodama in Japan ,in May 1980
The first patent was issued to Charles Hull for Stereolithography apparatus ( SLA )
SLA - 1 introduce ( 1987 )
Selective Laser Sintering ( SLS ) patent was issued to Carl Deckard
EOS sold its first 'stereos' system,
Fused Deposition Modeling ( FDM ) patent was issued to stratasys
Sanders Prototype ( Later Solidscape ) and ZCorporation were set up
Arcam was established
Objet Geometries launched
MCP technologies introduced the SLM technology
EnvisionTec was founded
Dr Bowyer conceived the RepRep concept of an open source , self-replicating 3d Printer
ExOne was established as a spin-off from the Extrude Hone Corporation
The first system under $10,000 from 3d system
Desktop Factory was acquired by 3d system
the first commercially available 3d printer - in kit form based on RepRap concept
Alternative 3d printing proccesses were introduced at the entry level of the market
Stratasys acquires Makerbot
2000s - present
Based to the history of 3D printing development there are 3 different types of methods that are used (SLS, FDM, SLA)
process almost any material; polymer, metal, ceramic and many types of composites
the laser beam and the powder material defines the feasibility and quality of any SLS process
Sintering is used for jewelry, bricks, and porcelain
Common plastics
Selective Laser Sintering ( SLS )
Fused Deposition Modeling (FDM)
Layer-by-layer, bottom up
Heating and extruding thermoplastic filament
Break away support material or it dissolves into water
