Activity 1.9 Design Innovation

Record the invention chosen by your team _____3D printer____________________

Research the invention chosen by your team. Discover at least the information below and document in your engineering notebook.

a.      When was the product invented?

Early 1980's (1983)

b.      What need did the product address?

It allows products to be manufactured close to purchasing points or consumption.

c.      Who invented the product?

Charles W. Hull

d.      List any existing patents.

There are 36 patents, but the most important one is the Apparatus for production of three-dimensional objects by stereo lithography

e.      What materials were originally used to make the product?

ABS plastic, PLA, polyamide (nylon), glass filled polyamide, stereolithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers and polycarbonate.

f.        How was the product originally made?

The 3d printer is made by assembling seven parts of it: the frame, y-axis, x-axis, z-axis, the extruder, the build platform, and the programming for electronics

g.      What improvements have been made to the product?

The 3d printer is faster, cheaper, and more mainstream. They now have high resolution scanners and the Ultimaker, which gives more printing room

h.     Why were these improvements made?

It was made to improve the quality of printed plastic products

i.        Who uses the product?

Big companies like Nike, Ford, and DIY Rockets use 3D printers to create various objects

j.         What is the global impact on society of the invention and subsequent innovations?

3D printing improves the accuracy and quality of manufactured items and are also known to speed up the creation of various manufactured products worldwide. 

k.      If you had the ability to change this product in any way, what would you change?

I would add a timer to display how long a certain product takes to be made.

Conclusion

1.      Define and differentiate invention and innovation.

 An invention is a product that is entirely new and addresses a problem in a new way. But, an innovation is different from an invention because it is an add-on to an already existing invention.

2.      What were the major factors that contributed to past innovations of the invention that you researched?

 Major factors include the customer satisfactio, the competition between companies, and the constant edition of innovations to the 3D printer.

3.      How has the pace of development changed through the history of the design?

 Before, companies did not have competition and worked slowly to create inventions, but now many companies are involved in creating innovations to try and beat other competing companies.

4.      What future innovations to the chosen invention do you predict?

I predict that there could be a timer to round how much time a product takes to make.

 Conclusion Questions

1.    What are the advantages and disadvantages to using an isometric pictorial compared to using an oblique pictorial in technical drawings?

 Oblique pictorials use a vanishing point and guide you but it requires estimation. Isometric pictorials use isometric graph paper and it is easier to sketch line, but you have to include the depth of an object

2.    What is the difference between a two-dimensional sketch and an isometric sketch?

 A two-dimensional sketch only give a perspective from one face, where an isometric sketch allows you to see an object from the three points of view at the same time.

3.    Why do designers use tonal shading?

Designers use tonal shading to make an isometric pictorial look more 3D. It also helps distinguish which side would be more exposed to the sun.
