Additive manufacturing in Aerospace
Transcript of Additive manufacturing in Aerospace
Founded by William Edward Boeing and George Conrad Westervelt in 1916.
Headquarter based in Chicago.
What is Additive
Additive Manufacturing is a new process that operates by adding rather than subtracting.
In conventional manufacturing, in cutting a part of titanium or aluminum, you are essentially wasting a large portion of that material.
Additive Manufacturing works on using a beam of lasers to cement powdered material into solid sections.
• Reduces wastage
• Allows for easy customization
• Can reduce outsourcing of
parts and sub assemblies
•Provides rapid prototype
Designing and Producing Shop Drawings of Object
Machining Parts – subtractive manufacturing
Measurement and Verification of Parts Dimensions: If NOT to requirements, part(s) are remanufactured.
If parts are the correct dimensions, they are assembled and the completed assembly is verified for correct operation. If NOT, corrections to the shop drawings are made and remanufactured. If it meets requirements, corrected as-built documents are produced.
3D Printing requires a digitized 3D designed model.
Computer Aided Design (CAD) or 3D Scanners are used to create the 3D Model.
Once the 3D model is created, the digital file is sent to a 3D printer for printing.
Once produced, the object is verified that it meets user requirements and specifications.
If NO, corrections are made to 3D Model and is re-printed.
If YES, 3D model is saved for future reproduction.
USE IN Aerospace field
Numerous airplane parts are currently being produced by this new production method due to the efficiency, speed and precision
ADVANTAGES IN AEROSPACE
COST OF GOOD SOLD IMPROVEMENT
LEAD TIME REDUCTION
REDUCE ENVIRONMENTAL IMPACT
OPPORTUNITIES FOR COMMERCIAL AVIATION
OPPORTUNITIES FOR SPACE
OPPORTUNITIES FOR MILITARY AND DEFENSE AIRCRAFT
Additive Manufacturing in Aerospace
Companies using this technology
AM TECHNOLOGY IN BOEING
Parts produced and used by Boeing
Environmental control ducts
GEnx engine for dream liner and new 747 series
Forward fuselage for fuselage for the F/A-18E/F
3D scanning technology on 747 line
Brackets and Bearings
power feed driller used in SLS drill plate
32 different components for 787 dreamliner planes
Rio de Janero
Earnings are mainly cash-backed
High Return On Equity; Boeing used only $5,867 of equity compared to the $82,929 from liabilities.
High Net Operating Asset Turnover (21.71) but lower Net Operating Profit Margin (5.03%)
Return On Assets is 4.98%, the company gets $0.0498 for each $1 in assets. This number tells us that Boeing is very asset-intensive.
Company generates enough cash by “liquidating” current assets to pay current liabilities.
•Using 2006 as our base year, net income has increased by 76%; however, in 2009 net income dropped below the base year by 41%.
Common size analysis:
•Boeing invests 4% on research and development whereas Lockheed only spends 1%. (These values are calculated as a percentage of sales)
•Boeing also makes a gross profit of 16% and Lockheed only makes 9%
A manufacturing company operating in more than 100 countries
EMPLOYEES 313,000 PEOPLE WORLDWIDE
Headquarters in Fairfield,CT
Additive manufacturing in GE
A game changer for the company
GE has over 300 3D printers across the company
$27m lab set up to use 3D printing in aircraft engines.
In 2012, the company acquired Morris Technologies and its sister company Rapid Quality Manufacturing in Cincinnati, Ohio. Both companies specialized in additive manufacturing.
Sales of 3D printers and related services rose 29 percent in 2012, to $2.2 billion
developed a fuel nozzle for the LEAP engine that is up to 25 percent lighter
Laser Sintering titanium into complex shapes
GE will need to make around 25,000 nozzles annually within three years.
By 2020, more than 100,000 additive parts are expected to be in service
In 2016, GE will enter a new jet engine into service called the CFM LEAP—the first in GE’s line to incorporate 3D-printed parts.
GE plans to spend tens of millions of dollars to invest in new technology and, over the next five years
the future of GE may include 3D printing ceramics, piezoelectrics, piezoceramics, resistors, inductors, and capacitors
100,000 3D printed parts in service within GE (GE9X) and CFM (LEAP) engines by 2020
vast knowledge of improving technologies
diversity in the work place
GE9x and leap engine in future
strong market growing
acceptance of new ideas
Diversified Product Portfolio
not having appropriate market research technology
loosing customers to new prospects for research and development
competitors honing in on vital market
Substantial Debt Burden
other competing companies
loss of economic resources
Since it is a powerful global brand, economic and political risks
Fluctuating currencies and economic recessions can affect global businesses severely
association and correlation with niche markets
Creating global relationships
Increased Demand for Commercial Airplanes
ADDITIVE MANUFACTURING IN THE AEROSPACE INDUSTRY
THEN, NOW AND THE FUTURE…..
KAWAL DEEP SINGH OLUSOLA iYIOLA
FUTURE OF ADDITIVE MANUFACTURING
Revenues from Additive Manufacturing to Reach $805 Million by 2019
The Lockheed Martin F-35 Lightning II fighter reportedly will have 900 AM parts
The PW1500G engine in Bombardier C series will contain 24 additively manufactured metal parts when it enters service in 2015.
Aircraft manufacturers material consumption by 75%
Use of concept of selective laser melting
Honeywell exploits it to build heat exchangers and metal brackets
Pratt & Whitney is using the technique in making blades and vanes for compressors inside jet engine
We appreciate Prof Farzard Rayegani for the opportunity he gave us to explore this important sector and for believing in Us.
“3D printers are only equipment, but equipment doesn’t do much if you don’t know how to use it
Dr. Farzad Rayegani,
We would like to express our gratitude to Professor Femi Adegun who has helped and supported us throughout our process from initial advice and contacts in the early stages of conceptual inception & through ongoing advice & encouragement to this day
