Applications 8. ConclusionWHAT IS 4D PRINTING? 4D printing is a variety of 3D printing. Basically, 4D printing is a renovation of 3D printing wherein special materials to print objects that change shape post-production. It is currently developed by industry leaders and research facilities like MIT’s Self-Assembly Lab, Stratasys, and Autodesk.So 4D Printing Is Basically Just 3D Printing? Then what’s so Special About it?HOW IT WORKS? With stratasys, connex technology, a single print with multi-materials features can transform from any 1D strand into 3D shape, 2D surface into 3D shape or more from 3D shape into another. The connex multi material technology allows the researchers to program different material properties into each of the various particles of the designed geometry and harnesses the different water-absorbing properties of the material to activate the self- assembly process. With water as its activation energy, this technique promises new possibilities for embedding programmability and simple decision making into non electronics based materials.4D PRINTING: THE TRIGGER MECHANISMS In 4D printing, you need some stimuli or trigger to start the transformation. These can include water, heat, light, electrical currents. There are other forms of triggers, some of which have to be explored in depth through research. Of course, you need special materials that are able to react to these triggers.  Of course, you need special materials that are able to react to these triggers. It’s making the objects “programmable” and execute their “genetic code” whenever you want to have it triggered.4D Printing: Self-Folding Strand into “MIT” 1.4D Printing: Self-Folding Strand into 3D Cube 2.4D Printing: Self-Folding Surface Cube 3.4D Printing: Self-Folding Truncated Octahedron 4.4D Printing: Curved-Crease Origami 5.4D Printing: Self-Folding Protein 6.4D PRINTING: WHAT’s NEXT?  4D printing is in the adolescent stages of becoming a science. 3D However, there are a few Self Assembling Industrial4D Environmental Printing Materials Manufacturing Printing concentrated groups of scientists across the Industry application Holds potential to revamp will be explored with globe who believe that manufacturing introducing a Exploring materials and cost of technology new field of environmental understanding reaction manufacturing the practicality of 4D more suited for in which to externalelements ambient sources of energy, industrial water or even light will be printing may become a applications used as impetuses to self- assemble reality and one of the fast growing technologies in the near 2013 2015 2035 2045 or medium-term future. Ongoing Research on 4D Printing There are a variety of examples that truly show how far this technology has come, from simplistic folding objects to programmable shape shifting materials and hydrogel composites. Years of research and testing will eventually lead to amazing inventions, such as adaptive water pipes and bricks, self-assembling structures, and even 4d printed soft robots.  The myriad of uses that can come from this technology are very enticing, so make sure to keep your eye on this new and engaging industry in the coming years as new developments facilitate the betterment of our lives in this wonderful world of tomorrow.OVERVIEW OF 4D OBJECT  Same materials change physical property upon energy input.  Materials expand upon heat Smart  Materials bend upon electric energy material  Natural energy source such as Energy heat, pressure, etc.  Controlled energy source such as Source current, electromagnetic wave Precise  Arrange transformative material in positioning precise angle, position. control  3D printerIMPORTANT ASPECTS OF 4D PRINTING 4D Printing Multi SMART Simulation materials materials Software printer 3D printer with Simulation Materials that capability to software for self- change shape assembly and print multiple upon external SMART design constraints stimuli optimization. materials Shape memory  Stratasys  Autodesk alloy  ROVA  CATIA Self  Open Source SolidView healing  GeoMagic materials
