Massive Open Online Course

Meaning of MOOC

Massive Open Online Course

Online courses that a student accesses through the internet.

Location Settings

The viewer can get visually specific sensations.

MOOC'S ENROLLMENT AND PACING

Varies by the type of course or program.

a) Selective Laser Sintering (SLS) b) Multi Jet Fusion (MJF) c) Direct Metal Laser Sintering (DMLS)

(3) POWDER BED FUSION

No physical location dependence

This can improve collaboration efforts and save time by eliminating a student's daily commute. Online education also enables social distancing.

Outdoor location, Indoor location

3D Environment can be done for both:

1. No physical location dependence 2. Improved access to higher education 3. Affordability of higher education 4. Flexible learning schedule

4 BENEFITS OF MOOC

4 TYPES OF 3D PRINTING TECHNOLOGIES AND PROCESSES

1) Detailed Concept Development 2) High-Definition Sketching 3) Environment Assets Creation 4) Hyper-Focused Texturing 5) High/Low-Poly Modeling 6) 3D Rendering & Optimization

6 SERVICES which are Commonly Included in the 3D environment Design services:

1) Vat Photopolymerization

A 3D printer based on this method has a container filled with photopolymer resin. The resin is hardened with a UV light source.

Wearable Technology

A category of electronic devices that can be worn as accessories, embedded in clothing, implanted in the user's body, or even tattooed on the skin. The devices are hands-free gadgets with practical uses, powered by microprocessors and enhanced with the ability to send and receive data via the Internet.

3D PRINTING

Additive manufacturing

Wearable Technology

Also known as "wearables"

Wearable Technologies

Any kind of electronic device designed to be worn on the user's body. Such devices can take many different forms, including jewelry, accessories, medical devices, and clothing or elements of clothing.

c) Direct Metal Laser Sintering (DMLS)

Basically, the same as SLS, but uses metal powder instead. All unused powder remains as it is and becomes a support structure for the object.

3D ENVIRONMENT

Can be taken as a computer-controlled digital setting, which appears as a background in the videogames and animated movies. It is created with the illusion of depth.

Certificates

Certificates for completing individual courses range from about $20 at the lower end, to around $300, with the average being between $50 to $100.

University Credit

Courses in this tier are university accredited and comparable to online courses at institutions that provide degrees.

Corporate Training

Deployed on an enterprise level. This pricing option is typically structured as a per-user cost for access.

b) Multi Jet Fusion (MJF)

Developed by Hewlett Packard and works with a sweeping arm which deposits a layer of powder and then another arm equipped with inkjets which selectively applies a binder agent over the material. The inkjets also deposit a detailing agent around the binder to ensure precise dimensionality and smooth surfaces. Finally, the layer is exposed to a burst of thermal energy that causes the agents to react.

3D PRINTING

Encompasses many forms of technologies and materials as 3D printing is being used in almost all industries you could think of. It's important to see it as a cluster of diverse industries with a myriad of different applications.

ASYNCHRONOUS

Flexible, self-paced courses

Massive Open Online Course

Free online courses available for anyone to enroll.

Wearables are electronic technology or devices incorporated into items that can be comfortably worn on a body. These wearable devices are used for tracking information on real time basis.

How Wearable Technology Works

2) 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 and then hardened by UV light.

SYNCHRONOUS

Instructor - facilitated Requires all participants to be virtually present at the same time. Scheduled and timed online tests, and virtual classrooms, web conferencing technology and interactive shared whiteboard.

Sheet Lamination

Involves material in sheets which is bound together with external force. Sheets can be metal, paper or a form of polymer.

3D LIBRARY

It's a massive library of 3D models including vehicles, characters, animals, architecture, devices, and more.

1. Free 2. Certificates 3. Micro-credentials 4. University Credit 5. Online Degree 6. Corporate Training

MOOC certification levels typically fall into the following 6 general categories:

Flexible learning schedule

Many courses are self-paced, which can accommodate student work schedules. Even if course completion is not self-paced, as with online degree programs, prerecorded lectures can offer more flexibility on a daily and weekly basis.

Improved access to higher education

Not only is this a function of convenience, but access to high-quality education in developing countries can ultimately increase quality of life and contribute to sustainable development efforts by providing a high-quality, accessible learning infrastructure.

Online Degree

Programs are equivalent to master's or continuing education degree programs at universities and offer comparable volume and depth of coursework.

Micro - Credentials

Programs typically consist of three to six courses. Typically, they are narrow in focus and provide a specific skill or competency.

Affordability of higher education

Scalability makes these types of courses more cost-effective than in-person courses of comparable scope.

ASYNCHRONOUS

Self directed - self paced Does not require all participants to be virtually present at the same time. Use message boards, discuss groups and self- paced online courses.

Free

These courses are completely free, but usually only to audit. However, students still have the option to pay for an official certificate of completion at the end of the course.

Directed Energy Deposition

This process is mostly used in the 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

a) Selective Laser Sintering (SLS)

Uses a high-power laser to fuse small particles of powder into a mass that has the desired three-dimensional shape. 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.

Advancements in Modeling

Visual effects of games and movies have been significantly improved with the advent of 3D computer graphics.

3) 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 required shape. First developed at the Massachusetts Institute in 1993.

4) Fused Deposition Modeling (FDM)

Works using a plastic filament which is unwound from a spool and is supplied to an extrusion nozzle which can turn the flow on and off. The object is produced by extruding melted material to form layers as the material hardens immediately after extrusion from the nozzle. Invented by Scott Crump in the late 80's.
