Welcome! Welcome to our blog. We're excited to begin this foray into 3D printing together with you, our readers. We started writing a formal research white-paper for our Digital Marketplaces course at Johns Hopkins Carey School of Business. We began using your standard management consulting report template, but figured delivery for this project made more sense in blog format. We have a lot of interactive videos and research we want to share with you, hence why we decided to post everything online. Below is some additional information on our group, as well as links to our Facebook and Twitter accounts. Social Media: 3D Printing at JHU Carey Facebook Page @Carey3DPrinting

3D printing (3DP) technology was invented in early 80's. The technology is similar to inkjet printing, but allows us to print out tangible objects instead of using ink. 3DP uses " additive manufacturing," which means that the printing process output involves printing in successive layers using different materials. 3DP can be categorized to two different types, depending on the purpose of production.
Type of 3D printing
Advantages of using 3DP
Hobbyist 3D printing
- People with
comparatively cheap machines print plastic objects in their homes
- Customize anything you already own
Industrial 3D printing
(Additive manufacturing (AM))
- Change assembly
line, some process can be eliminate and combine in one station
- Eliminate the
outsource process
- Easier to make
change to the design
- Inventory
management
- Decrease labor and
cost (in some country this might be a problem)
- Reduce waste of
raw material
There are four major players in the 3D-printer-maker
market. Stratasys, 3D Systems, ExOne and Makerbot. The first three are public
companies. In 2011, MakerBot had 21.6% market share. In 2012, MakerBot estimates that it now has 25% market
share in the 3D printer market.
Prices of 3D printers can range from
$200 to $10,000. The materials are mainly plastic, but there are machines that
can print out glass, sugar, aluminum or ceramics. Makerbot’s oldest version 3D
printer called Cupcake can only print out 10x10x10 cm object, but the latest version,
which is called ReplicatorTM 2X, can print out 15x15x30 cm objects.

President Obama highlighted 3DP in State of the Union Address. The government planned to build three more manufacturing hub that will connect high tech with government sectors, and 3DP plays an important role in the plan. It is no doubt that 3DP will have huge impact on various industries, or even individual like us.
3D printing, abridged to 3DP by early adopters, has opened up the borders
of design and manufacturing to new and smaller companies, designers, and
innovators. Sharing designs for prototypes across multiple time zones,
rapid and instantaneous development of building models in AutoCAD, and printing
all of these items in-house has reduced the cost and increased the access of
innovation in design and architecture. But 3D scanning technology is still in
early development phase. There remain significant barriers and limitations to
the technology. Most objects that are textured and opaque can be scanned into a
computer, analyzed and deconstructed by software, and received as a 3D
model. (Source: Independently produced video footage from New York
Expo) Some textured objects; translucent materials like glass, extremely
large objects, and shiny objects can still not be processed well by scanning
software. 3D scanning is still evolving is because it developed out of a need
to fill the knowledge gap between experienced 3D software users and customers
new to the product. Therefore, 3D scanning is a necessity within the 3D
technology spectrum and should remain accessible and easy to use for the
average consumer.
Source: Engineering.com For prototyping applications, 3D printing is
widely recognized as an efficient way of proving new ideas and concepts. The access
and low costs that 3D printing provides allow designers to develop multiple,
cost-effective iterations during the design process.3D printing creates
infinitely customizable, tangible products. It allows for rapid manufacturing
and on-demand customization, which also increases demands from clients and
customers.
Designers
are able to use 3D printing to provide them with opportunities to make their
ideas come to life and build actual models instead of theoretical models. 3D
printing offers product developers the ability to print different parts of a
model using multiple materials simultaneously.These materials can have different mechanical, composite, and versatile
properties, but are flowing through the same 3D printing device. Companies such as Stratasys are selling 3D
printers that incorporate materials that the first iteration of 3D printers was
not able to combine.Printers like the
Objet Connex500 use over-molding, which is an injection molding process
involving two materials molded together, and double-injection, which is the
process of molding plastic around a preformed plastic or metal core. (Source:

Right is a design of a lamp mold, before the product has
been manufactured. Customers are afforded the opportunity to have 3D insight
into what the lamp-shade will look like from all angles via a 3d mold, printed
for under $4.00 a cubic inch. From there, additional customization can occur.
Customers and clients are given clearer and vivid knowledge of the product
because of 3D modeling and printing. Here is a video that shows how 3D printing can help distinguish and improve efficiency. It helps illustrate the concept of 3D printing and the models it produces for clients.
3D printing provides designers and architects
with an accessible, cost saving, and efficiency-improving technology. Architects will have more time to focus on
design ideas, as the structural worries most designers face are solved using 3D
printing and modeling. It also provides
them with a tracking mechanism to improve designs for clients upon request, but
also not lose any details or previous tweaks in design. Some examples of 3D
software-to-market are below:
The picture below was created by a designer, inspired by
beautiful lamp shades he found on his first visit to Thailand a couple years
ago. They are normally quite expensive,
but he utilized 3D design software to design something similar and began printing his own.
Finally there is a
fun quick 3D Printing Art Exhibition, where the display arts are all 3D
printing products from Objet, the leading producer of advanced,
inkjet-based 3D printers working in collaboration with the young designers of
Keter Plastic's d-Vision, has donated these 3D printed art pieces to a charity
auction to raise money for social and educational youth programs. The
charity auction was hosted at the renowned Design Museum.
