INTRODUCTION

• As 3D printers are become more affordable and
  versatile, they are destined to disrupt multiple
  industries. Here's what you need to know about
  this quickly accelerating technology.
• The world of 3D printing is exciting. With more
  affordable machines, creative entrepreneurs,
  innovative start ups, and new materials, the
  industry is rapidly evolving.
• Since the invention of the 3D printer in 1983 by
  Chuck Hull of 3D Systems, companies have popped
  up all over the globe, attempting to make the
  most innovative machine.
• Now there are 9 types of essential 3D printers
  available, which are very popular nowadays.

Fused Deposition Modelling

• FDM is the most common 3D printing method used
  in desktop 3D printing. Thermoplastic filament is
  heated and extruded through an extrusion head
  that deposits the molten plastic in X and Y
  coordinates, while the build table lowers the
  object layer by layer in the Z direction.
• Effectively, the object is built from the bottom
  up. If an object has overhanging parts, however,
  it will need support structures that can
  be removed after the printing is finished.
• This type of 3D printers is a cost-effective means
   for product development and rapid prototyping in
  small business and education sectors since its
  capable of fabricating robust parts reliably and
  quickly.

Stereo lithography

• SLA has the distinction of being the oldest of
  the 3D printing technologies, first invented by
  Chuck Hull in 1983.
• SLA works by exposing a layer of photo sensitive
  liquid resin to a UV-laser beam so that the resin
  hardens and becomes solid. Once the laser has
  swept a layer of resin in the desired pattern and
  it begins to harden, the model-building platform
  in the liquid tank of the printer steps down the
  thickness of a single layer, and the laser begins
  to form the next layer. Each layer is built on
  top of the preceding one.
• SLA creates smooth surfaced objects with extreme
  detail, and its increasingly popular in
  industries like jewelry and cosmetic dentistry
  for creating cast able moulds.

Digital Light Processing

• Digital Light Processing (DLP) and Stereo
  lithography have a lot in common. Both types of
  3D printers use liquid photopolymers. You might
  have heard of these resins. DLP and SLA
  printers cure them by applying light to it. SLA
  does that with a laser, DLP with a special
  projector.
• DLP technology was invented in 1987 by Larry
  Hornbeck of Texas Instrument and became extremely
  popular in projectors. DLP uses a
  computer-controlled, micro-mirror grid, laid out
  on a semiconductor chip. These tiny mirrors tilt
  back and forth. When a mirror is tilted, it
  reflects light, creating a bright pixel.
• The technology is used in movie projectors, cell
  phones, and also for 3D printing. One of the
  benefits for 3D printing is its speed You can
  print layers in an instant with this type of 3D
  printer.

7
Selective Laser Sintering

• SLS is similar to SLA, but the key difference is
  that this type of 3D printer uses powdered
  material in the build area instead of liquid
  resin. A laser is used to selectively sinter a
  layer of granules, which binds the material
  together to create a solid structure. When the
  object is fully formed, its left to cool in the
  machine before being removed.
• SLS is widely used for product development and
  rapid prototyping in a wide range of
  commercial industries, and also for limited-run
  manufacturing of end-use parts. 
• The materials used in SLS can range from nylon,
  glass, and ceramics to aluminium, silver,
  and even steel.

8
Selective Laser Melting

• SLM is sometimes regarded as a subcategory of the
  SLS 3D printer type, where SLM uses a
  high-powered laser beam to fully melt metallic
  powders into solid three-dimensional parts.
• Typical materials used are stainless steel,
  aluminium, titanium, and cobalt chrome. For
  applications in the aerospace or medical
  orthopaedics industry, SLM is used to create
  parts with complex geometries and thin-walled
  structures, with hidden channels or
  voids. Elsewhere, as in the video above, its
  been used to fabricate gas turbines for the
  energy industry.

Electron Beam Melting

• In contrast to SLM, the EBM technique uses a
  computer-controlled electron beam under high
  vacuum to fully melt the metallic powder at high
  temperatures up to 1000 C.
• This type of 3D printer can use metals like pure
  titanium, Inconel718, and Inconel625 to
  fabricate aerospace parts and medical implants.
  But while the 3D printer technology is exciting,
  its currently very slow and very expensive.

10
Laminated Object Manufacturing

• LOM uses layers of adhesive-coated paper, plastic
  or metal laminates, which are fused under heat
  and pressure and shaped by cutting with a
  computer controlled laser or knife. This is
  sometimes followed by machining and drilling. The
  3D object is created layer-by-layer, and after
  the excess material is cut away, the object can
  be sanded or sealed with paint.
• Though the dimensional accuracy of this 3D
  printer type is slightly less than SLA or SLS,
  LOM is one of the most affordable and fastest 3D
  printing methods available to create relatively
  large parts. It also allows for full-colour 3D
  printed objects.

11
Binder Jetting

• Binder Jetting is an additive manufacturing
  process. This type of 3D printer uses two
  materials a powder based (often gypsum) material
  and a bonding agent. The agent acts as an
  adhesive between powder layers. Usually, the
  binder is extruded in liquid form from a print
  head just think of a regular inkjet 2D printer.
  After a layer is finished, the build plate is
  lowered and the process repeated. 
• You can use this 3D printing technology with
  ceramic, metal, sand or plastic materials.
• These type of 3D printers have a huge advantage.
  You can print in full-colour by adding pigments
  to the binder (usually cyan, magenta, yellow,
  black and white). This made it the preferred
  method for the popular 3D selfies. The drawback
  of this 3D printing method is the structural
  integrity of the objects. You wont get
  high-resolution and rugged prints with this type
  of 3D printer technology but there are some
  exceptions.

12
Wax Casting

• The Material Jetting technology is better known
  as wax casting. Theres no inventor per se
  its a technique used by jewellers since
  centuries. Lost wax casting (or investment
  casting) is a production process that mainly
  allows you to produce customizable jewelry of
  very high quality in various metals. But with 3D
  printing, theres finally a process to automate
  wax casting and for most jewellers, that quite
  something.
• So it has become the dominant type of 3D printing
  technology if youre a jeweller or want to
  experiment with casts. 
• There are a handful of professional wax 3D
  printers on the market, like the Wax Jet from
  Statasys. If you want to experiment with this 3D
  printing technology, you dont have to buy a
  printer. There are 3D printing services like
  Shape ways or Sculpted which use Material Jetting
  or Multi jet Modelling (MJM) machines for this
  task.
