Terminology: 3D Printing versus Additive Manufacturing

    The terms 3D printing and additive manufacturing evolved into alternate general terms for additive technologies, one being used popularly by consumer-maker communities and the media, and the other used more formally by industrial end-use part producers, machine manufacturers and global technical standards organizations. Alternative terminology that has been utilized as synonyms or hypernyms includes desktop manufacturing, rapid manufacturing (considered the logical production-level successor to rapid prototyping), and on-demand manufacturing. The introduction of the terms rapid and on-demand in conjunction with manufacturing during the 2000s highlights the longstanding mental framework of the preceding industrial era, characterized by extensive lead times associated with labor-intensive tooling development in nearly all manufacturing processes. The term 3D printing was popularized by Emanuel Sachs from the Massachusetts Institute of Technology (MIT), and was used in1989 in a patent on a binder jetting process. By the early 2000s, media outlets around the world were using 3D printing as a common vernacular to refer to AM. By the end of the 2000s, the term was entrenched for multiple uses: reference to the MIT binder jetting process, to AM in general, and, specifically, to low-cost AM machines.

Evolution of Modern Additive Manufacturing

Additive manufacturing in 1980s saw its early development and commercialization. This period laid the foundation for the modern AM technologies. Here is brief timeline of key events.

1980s

    • 1980: Hideo Kodama invented two additive methods for fabricating three-dimensional plastic models with photo-hardening thermoset polymer, where the UV exposure area is controlled by a mask pattern or a scanning fiber transmitter.
 

    • 1984: Bill Masters filed a patent for his computer automated manufacturing process and system. This filing is on record at the USPTO as the first 3D printing patent in history; it was the first of three patents belonging to Masters that laid the foundation for the 3D printing systems used today.
 
    • 1986: The groundwork for additive manufacturing can be traced back to the invention of Stereolithography (SLA) by Chuck Hull.
 
    • In 1984 a patent, assigned to Chuck Hull was filed,his own patent for a stereolithography fabrication system, in which individual layers are added by curing photopolymers with impinging radiation, particle bombardment, chemical reaction or just ultraviolet light lasers. Hull defined the process as a "system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed". Hull's contribution was the STL (Stereolithography) file format and the digital slicing and infill strategies common to many processes today.
 
    • In 1986, Charles "Chuck" Hull was granted a patent for this system, and his company, 3D Systems Corporation was formed and it released the first commercial 3D printer, the SLA-1 later in 1987. Deckard invented selective laser sintering in 1986.
 
    • 1987: 3D Systems patents a method for metal sintering, laying the foundation for future developments in metal AM.
 
    • 1988: The first metal AM technology, Selective Laser Sintering (SLS), was developed, allowing for the creation of metal parts by selectively melting powdered metal using a laser.
 
    • 1988: The technology used by most 3D printers to date—especially hobbyist and consumer- oriented models—is fused deposition modeling, a special application of plastic extrusion, developed by S. Scott Crump and commercialized by his company Stratasys, which marketed its first FDM machine in 1992.
 

1990s

    • By the late 1990s additive manufacturing was still mainly used for rapid proto typing rather
      then end use production. However key technologies like SLA, SLS and FDM were
      established setting the stage for AM expansion in 2000s. Various metal AM techniques
      emerged, including Laser Engineered Net Shaping (LENS) and Direct Metal Laser Sintering
      (DMLS), which allowed for the production of fully dense metal parts from powder. The
      introduction of Electron Beam Melting (EBM) in this period allowed for the production of
      complex geometries using electron beams to melt metal powder.

 

    • 1992: Selective Laser Sintering (SLS) is developed by Carl Deckard at the University of
      Texas, capable of processing metal powders, marking a significant advancement.

 

    • 1993: The term 3D printing originally referred to a powder bed process employing standard
      and custom inkjet print heads, developed at MIT by Emanuel Sachs and commercialized by
      Soligen Technologies, Extrude Hone Corporation, and Z Corporation. Their direct shell
      production casting used an inkjet mechanism to deposit liquid binder onto ceramic powder to form shells for use in the investment casting process. The year 1993 also saw the start of an inkjet 3D printer company initially named Sanders Prototype, Inc and later named Solidscape, introducing a high-precision polymer jet fabrication system with soluble support structures, (categorized as a "dot-on-dot" technique).

 

    • 1995: the Fraunhofer Society developed the selective laser melting process. Fockele & Schwarze of Germany introduced its steel-powder-based selective laser melting system in 1999, developed in cooperation with the Fraunhofer Institute for Laser Technology. This wasthe harbinger of a series of high-power directmetal machines for laser-based powder-bed fusion.

 

    • 1997: Arcam, a Swedish company, was founded. Its principal product was an electron-beam-based powder-bed fusion machine based on development in collaboration with Chalmers University of Technology in Gothenburg (Ref 42).

2000s

                         Metal AM began to gain traction in industries such as aerospace and medical due to its ability  to produce lightweight, complex geometries that traditional manufacturing methods could not
achieve. Companies like 3D Systems and Stratasys expanded their offerings to include metal
printing systems, making the technology more accessible.

    • 2000: The first commercial metal AM systems are introduced. Notably, EOS releases the
      EOSINT M series, which uses laser sintering for metal parts.
    • 2001: 3D Systems acquired DTM Corp., the first commercial powder-bed fusion company.
    • 2003: The German company EOS commercialized the EOSINT machine based on laser
      sintering technology in 1994. EOS introduced its EOSINT M 270 direct-metal laser sintering
      machine.
    • 2005: Direct Metal Laser Sintering (DMLS) technology is patented by SLM Solutions,
      enhancing the ability to produce complex metal components with high precision.
    • 2010: The first 3D-printed metal parts for aerospace applications are produced, showcasing
      the technology's potential in high-performance industries.
    • 2013: The U.S. Air Force and other military organizations begin to invest in metal AM for
      the production of lightweight and durable components.

    • 2014: The first metal 3D printer, the Desktop Metal Studio System, is introduced, aimed at
      making metal AM accessible to small and medium-sized enterprises.

      In the early 2000s 3D printers were still largely being used just in the manufacturing and
      research industries, as the technology was still relatively young and was too expensive for
      most consumers to be able to get their hands on. The 2000s was when larger scale use of the
      technology began being seen in industry, most often in the architecture and medical
      industries, though it was typically used for low accuracy modelling and testing, rather than
      the production of common manufactured goods or heavy prototyping.
      In mid of 2000s much of the software for 3D printing available to the public was open source,
      and as such was quickly distributed and improved upon by many individual users. In 2009 the
      Fused Deposition Modeling (FDM) printing process patents expired. This opened the door to
      a new wave of startup companies, many of which were established by major contributors of
      these open source initiatives, with the goal of many of them being to start developing
      commercial FDM 3D printers that were more accessible to the general public. [40]

6. Jealous: 

Jealousy = Budha. Look at the 3rd and 6th house, governed by Budha. Also, Rahu gets Uccha in the 3rd house and Mulatrikona in the 6th house, indicating strong Rahu influences on these two houses.

7. Stammering speech: 

 Strong Agni = High metabolism.

8. Troubled by Bilious and Windy diseases, and complaints of heat:

Bilious = Strong Agni. Windy is caused by Strong Agni as Agni and Vayu are strong friends.

9. Skilful in performance: 

 High energy level. This skill is coming from Mangal and Surya.

10. Timid:

Strong Benefic influence on the 3rd house. The 3rd house from Mesha is ruled by Budha indicating Timidity.

11. Religious:

9th house is ruled by Devaguru Brhaspati.

12. Not very intelligent: 

Here intellect does not mean the ability to reason, but the ability to choose the right thing at the right time and place. This is because strong influence of Surya on the lagna and the 5th house. Surya makes one behave according to own wish, instead of adapting to the expected norms.

13. Destroy others’ wealth: 

 Others = 7th house, Other’s wealth = 8th house. 8th house falls in Vrschika Rasi, where Chandra gets Neecha.

14. Fickle-minded:

 Strong influence of Mangal on the Head. Mangal and Chandra are two grahas which cause fickle-mindedness.

15. Enjoy pleasures: 

4th house is the house of comfort, governed by Chandra and is the Uccha sthana for Guru. Hence, this indicates that these natives are fond of comforts and luxuries on life.

16. Famous: 

 Surya gets Uccha in the Lagna. The Lagna lord gets Uccha in the 10th house. Guru and Chandra are comfortably placed in the Lagna.

17. Ugly nails: 

 Shani gets Neecha in the Lagna, indicating that these natives have some issues pertaining to things governed by Shani.

18. Bereft of Brothers: 

 Especially elder brothers are less born to these natives, as the 11th is owned by Shani and Rahu. Whichever Bhava has strong influence of Shani and Rahu, the native is either separated from the significations of that Bhava or have suffering pertaining to them.

19. Abandoned by father: 

Separation of father is indicated because 9th lord gets Neecha in the 10th house and the Lagna lord gets neecha in the 4th house. Weakness in the 4th-10th axis indicate early separation from father. Another combination is Surya Uccha or Neecha in the 1st- 7th axis.

20. Walk fast: 

 Strong Agni influence. Chara Rasi.

21. Inactive (or unlucky) children: 

 Strong Agni Tattva in the 5th house can cause anxiety or separation from Children.

22. Various kinds of wealth:

Precious metals and stones are given by Surya and Chandra, who are well placed in the lagna. Also, the 2nd house of wealth is owned by Shukra and is the Ucchakshetra for Chandra.
Shukra = luxuries.
Chandra = precious stones, good food etc.

23. Virtuous: 

Guru and Surya are good friends to this Lagna. Strong Surya destroys all darkness and strong Guru gives good guidance to be in the righteous path.

24. Wife belongs to a base family: 

 Shani is the only inimical Graha towards Lagnesha Mangal, while Shukra and Budha are only neutral. The weakness is where the enemy gets Uccha. Shani attains Uccha in the 7th house, indicating that this will be the area of weakness in these native’s life.

25. Reproached even by her own people: 

 Friends are seen from the 11th house. The 11th house is governed by Shani and Rahu, who are inimical towards the Lagnesha Mangal. Thus, these natives are reproached by the friends and well-wishers.
Also 4th house is the Bandhu Bhava i.e., the people who makes the person comfortable. Lagnesha is Neecha in the 4th house, indicating that these people find it difficult to get comfort from others.

26. Derive happiness and wealth in undesirable manners: 

 This is an extreme condition because, Mangal gets Neecha in the house of comforts i.e., the 4th house. Indicating that the native can resort to Neecha Means (undesirable means) to get comfort.
