Additive manufacturing, commonly referred to as 3d printing, is a manufacturing
technique that rises in the 1980’s mainly focused on engineering prototyping. Current
advances in the precision and cost of the techniques, as well as the widespread use of 3d
designing have increased 3d printing’s scope of use from high-end engineering prototypes
to a large variety of uses in manufacturing. 3d printing improve the processing time,
decrease waste, and increase the level of customization of certain products by eliminating
the need for the specialty tooling and dies that are traditionally used in manufacturing. In
addition, the ability to physically print difficult shapes based on a computer model has
given rise to new products that would otherwise be simply impossible to create. The
various fields have taken advantage of this technology by printing 3d objects.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2. What is 3D printing?
3D printing or additive manufacturing is a process of making three dimensional
solid objects from a digital file. The creation of a 3D printed object is achieved
using additive processes. In an additive process an object is created by laying down
successive layers of material until the entire object is created. Each of these layers
can be seen as a thinly sliced horizontal cross-sectionof the eventual object.
How does 3D printing work?
It all starts with making a virtual design of the object you want to create. This
virtual design is made in a CAD (Computer Aided Design) file using a 3D
modeling program (for the creation of a totally new object) or with the use of a 3D
scanner (to copy an existing object). A 3D scanner makes a 3D digital copy of an
object.3d scanners use different technologies to generate a 3d model such as time-
of-flight, structured / modulated light, volumetric scanning and many more.
Recently, many IT companies like Microsoft and Google enabled their hardware to
perform 3d scanning, a great example is Microsoft’s Kindest. This is a clear sign
that future hand-held devices like smart phones will have integrated 3d scanners.
Digitizing real objects into 3d models will become as easy as taking a picture.
Prices of 3d scanners range from very expensive professional industrial devices to
30 USD DIY devices anyone can make at home.
Below you’ll find a short demonstration of the process of 3D scanning with a
professional HDI 3D scanner that uses structured light:
To prepare a digital file for printing, the 3D modeling software “slices” the final
model into hundreds or thousands of horizontal layers.
3. Processes and technologies
Not all 3D printers use the same technology. There are several ways to print and all
those available are additive, differing mainly in the way layers are build to create
the final object.
Some methods use melting or softening material to produce the layers. Selective
laser sintering (SLS) and fused deposition modeling (FDM) are the most common
technologies using this way of printing. Another method of printing is when we
talk about curing a photo-reactive resin with a UV laser or another similar power
source one layer at a time. The most common technology using this method is
called stereo lithography (SLA).
To be more precise: since 2010, the American Society for Testing and
Materials (ASTM) group “ASTM F42 – Additive Manufacturing”, developed a
set of standards that classify the Additive Manufacturing processes into 7
categories according to Standard Terminology for Additive Manufacturing
Technologies.Theseseven processesare:
1. Vat Photo polymerization
2. MaterialJetting
3. Binder Jetting
4. MaterialExtrusion
5. Powder BedFusion
6. SheetLamination
7. Directed EnergyDeposition
Vat Photo polymerization
A 3D printer based on the Vat Photo polymerization method has a container filled
with photopolymer resin which is then hardened with UV light source.
4. Vat photo polymerization schematics. Image source: lboro.ac.uk
The most commonly used technology in these processes is Stereo lithography
(SLA). This technology employs a vat of liquid ultraviolet curable photopolymer
resin and an ultraviolet laser to build the object’s layers one at a time. For each
layer, the laser beam traces a cross-section of the part pattern on the surface of the
liquid resin. Exposure to the ultraviolet laser light cures and solidifies the pattern
traced on the resin and joins it to the layer below.
Material Jetting
In this process, material is applied in droplets through a small diameter nozzle,
similar to the way a common inkjet paper printer works, but it is applied layer-by-
layer to a build platform making a 3D object and then hardened by UV light.
5. Binder Jetting
With binder jetting two materials are used: powder base material and a liquid
binder. In the build chamber, powder is spread in equal layers and binder is applied
through jet nozzles that “glue” the powder particles in the shape of a programmed
3D object. The finished object is “glued together” by binder remains in
the container with the powder base material. After the print is finished, the
remaining powder is cleaned off and used for 3D printing the next object. This
technology was first developed at the Massachusetts Institute of Technology in
1993 and in 1995 Z Corporation obtained an exclusive license.
7. Fused deposition modeling (FDM), a method of rapid prototyping: 1 – nozzle
ejecting molten material (plastic), 2 – deposited material (modeled part), 3 –
controlled movable table. Image source: Wikipedia, made by user Uzbeks under
CC Attribution-Share Alike 4.0 International license.
The FDM technology works using a plastic filament or metal wire which is
unwound from a coil and supplying material to an extrusion nozzle which can turn
the flow on and off. The nozzle is heated to melt the material and can be moved in
both horizontal and vertical directions by a numerically controlled mechanism.
Powder Bed Fusion
The most commonly used technology in these processes is Selective laser
sintering (SLS)
8. SLS system schematic. Image source: Wikipedia from user Material geezer under
Creative Commons Attribution-Share Alike 3.0 Unsorted license
This technology uses a high power laser to fuse small particles of plastic, metal,
ceramic or glass powders into a mass that has the desired three dimensional shapes.
The laser selectively fuses the powdered material by scanning the cross-sections
(or layers) generated by the 3D modeling program on the surface of a powder bed.
After each cross-section is scanned, the powder bed is lowered by one layer
thickness. Then a new layer of material is applied on top and the process is
repeated until the object is completed.
All untouched powder remains as it is and becomes a support structure for the
object. Therefore there is no need for any support structure which is an advantage
over SLS and SLA. All unused powder can be used for the next print. SLS was
developed and patented by Dr. Carl Deckard at the University of Texas in the mid-
1980s, under sponsorship ofDARPA.
9. SheetLamination
Sheet lamination involves material in sheets which is bound together with external
force. Sheets can be metal, paper or a form of polymer. Metal sheets are welded
together by ultrasonic welding in layers and then CNC milled into a proper shape.
Paper sheets can be used also, but they are glued by adhesive glue and cut in shape
by precise blades. A leading company in this field is Moro Technologies
Directed EnergyDeposition
This process is mostly used in the high-tech metal industry and in rapid
manufacturing applications. The 3D printing apparatus is usually attached to a
multi-axis robotic arm and consists of a nozzle that deposits metal powder or wire
on a surface and an energy source (laser, electron beam or plasma arc) that melts it,
forming a solid object.
10. Examples& applicationsof 3D printing
Applications include rapid prototyping, architectural scale models & banquettes,
healthcare (3d printed prosthetics and printing with human tissue) and
entertainment (e.g. film props).Other examples of 3D printing would include
reconstructing fossils in paleontology, replicating ancient artifacts in archaeology,
reconstructing bones and body parts in forensic pathology and reconstructing
heavily damaged evidence acquired from crime scene investigations.
3D printing industry
The worldwide 3D printing industry is expected to grow from $3.07B in revenue in
2013 to $12.8B by 2018, and exceed $21B in worldwide revenue by 2020. As it
evolves, 3D printing technology is destined to transform almost every major
industry and change the way we live, work, and play in the future.
