Process principle for FR2 (glue two layers of materials):

Page 10: Principle – more than 3D Printing but Additive Manufacturing Primary questions: How can be one solid layer formed? How can two layers be adhered? Process.

The principle to glue the two layers is the photosensitive effect - i.e., the gluing of the upper layer of liquid to the previous solid layer is completed during the solidification of the upper layer of liquid.

Principle – more than 3D Printing but Additive Manufacturing

Rectification for 3D Printing (in terms of the principle):

3D Printing is a kind of additive manufacturing technology.

The principle of 3D printing is molten material will solidify quickly in a

sufficient low temperature environment.

3D printing directly dispenses molten materials to the object (an initial

platform or solid layer of the materials).3D printing glues two layers of the materials (a previous solid layer and a

layer of liquid in the process of solidification) based on the heat-fusion.

3D printing = Fused Deposition Modeling (FDM) = Fused Filament Fabrication

(FFF) = RP (rapid prototyping).

Analysis: Pros and Cons

Pros of additive manufacturing technology:

1.No need of tooling for making a product, thus most suitable for concept

design and marketing.

2.Capable of making complex internal features, thus most suitable for

tissue engineering.

3.Highly customization, thus most suitable to tissue engineering.

4.Rapid production compared with those that need tooling.

5.Low cost in production compared with those that need tooling.

6.Large design space due to its capability of making complex shape

products.

7.High sustainability.

Concluding Remarks

Corrigendum and Position Statement: revisit

3D Printing is not the everything of manufacturing technology but a

manufacturing technology that is

of universal capability in terms of making the shape of product,

agile in terms of readiness of accessibility and availability, and

Suitable to one-kind-of-production (OKP).

Add:

3D Printing is one of the additive manufacturing technologies.

Fused deposition principle, leading to simple equipment set up.

It is most promising in bio manufacturing, including design, fabrication and

control.
