Help me!
Please help me with reporting information that exists but not shown under a topic. I have a 3D printing collection of documents and hardware and want to use it as support for the contribution in Wikipedia. I am not a good writer and would like help.

 * The policy on Wikipedia is you can use primary sources (such as the documents you have?) as a source, but any interpretation of that material has to be made by a secondary source covering that topic (i.e. someone writing a history of 3D printing who is authoritative enough to give a reliable overview of the topic).


 * So, you should look at these types of sources to pair up with the material you have:
 * 
 * 


 * If you can rewrite from stuff like that it should be ok.


 * BTW some of the articles you are trying to link are showing up at Solidscape. Fountains of Bryn Mawr (talk) 15:14, 17 August 2018 (UTC)

Help me!
I want to be a contributor to the Wikipedia Free Encyclopedia. I worked at Sanders Prototypes. Inc as the first Service manager, I supplied Sanders Prototypes. Inc with inkjets for the first years production of the Modelmaker 6 pro, I worked for Howtek, Inc as a mechanical engineer who helped design the inkjets for 2D printers. I have information that is not included in the Wikipedia Encyclopedia that shows the inkjet technology in the Modelmaker 6 Pro originated at Howtek, Inc. The ink for the Modelmaker 6 Pro also came from Howtek, Inc. My business web site is layergrownmodel.com and it has information about anything I want to add to the Wikipedia Free Encyclopedia. I have a facebook page, James.K.McMahon which also has the information. I also have a web page 3Dinkjetmuseum.com with the same information. Why can't I just reference myself. I am the historian.

 * "Why can't I just reference myself. I am the historian."
 * Please see WP:RSSELF and WP:SELFPUBLISH. In general, Wikipedia is not an encyclopedia that you cite using your own knowledge, you cite it using others peoples books, magazine articles, authoritative websites, etc. None of that is there to stop you from adding material based on what you know. If you are a historian on the matter you should be able to cite other sources on this. A problem comes up when you try to claim something was "the first", you really can't cite yourself, that has to come from other reliable sources.

The Godfather of Inkjet 3D Printing moved to draftspace
An article you recently created, The Godfather of Inkjet 3D Printing, does not have enough sources and citations as written to remain published. It needs more citations from reliable, independent sources. (?) Information that can't be referenced should be removed (verifiability is of central importance on Wikipedia). I've moved your draft to draftspace (with a prefix of " " before the article title) where you can incubate the article with minimal disruption. When you feel the article meets Wikipedia's general notability guideline and thus is ready for mainspace, please click on the "Submit your draft for review!" button at the top of the page.

As a founder of Howtek, Inc which has direct connections to the inkjet 3D Printing technology that I am referring too, I am organizing a meeting of the original Howtek founders to discuss ideas that for years have been set aside and hidden from the general public. Inkjet history is colorful and exciting to me. My experience and now my research has led me to find many new things and introduced me to people in the industry who did not know they were really connected to it. The idea that 3D printing is new to those working in the field in recent times and unknown by those who patented things not knowing that it was actually the early days of 3D printing has been fun to share with others. I think the world needs to hear about the patents and people who experimented with 3D printing materials or who worked in printing years ago and eventually ended up in 3D printing industries today. The current publicized information about 3D printing has been established by a few companies and these others that should be recognized have been hidden for years. It is my goal as the godfather of 3D Inkjet printing to bring to light the stories of the printing and show it actually was the path to 3D Printing. 3D Printing didn't just happen on day by one person, it was an ongoing activity that started back in the 1950's but took the graphics industry and gaming to open our eyes to it in the 1980's and then it exploded with new patents. The patents actually silenced progress until they expired and then the industry was free to grow. I want to share my experience here in Wikipedia and I am afraid no one else will do it if I don't speak up. Historian and Godfather of Single nozzle inkjets (talk) 09:41, 7 December 2020 (UTC)

Archives.lib.umm.edu/agents/corporate/entities/240 contains Markets and Product reports collections: Identifier CBI 55 Found in the Charles Babbage Institute Collection a report "UPDATE ON INK JET PRINTING TECHNOLOGY APRIL THROUGH JUNE 1986", PAGE 2 on the subject of Hot Melt Ink Jet, Howtek's top founder, Robert Howard came further out of the closet this quarter by the first public showing at Comdex/Spring 1986 in Atlanta the Pixelmaster with specifications sheet printed on Fig IJ-3 of this report. It states "Pixelmaster as the first Hot-melt ink-jet product to be offered on the market, having an unorthodox paper handling method, designed as a floor standing tower, including color whether you want it or not, but most of all with the distinctive feel and appearance of ink sitting on the paper surface". One of Howtek's founders went on to a 3D Printing patent using the Howtek drop-On Demand technology and inks with a raised effect as described on the "The Howtek HT-1 Color Jet Printer single-page document copyright in 1985. I will get permission to show these documents soon and then you can read it with your own two eyes. It is clear that ink jet hotmelt printing was the path forward to 3D printing with a printer product and patents to back it up. It was publicly announced and published. I hope others will find the information worth reviewing in Wikipedia when I get permission to add it. Further information will be added to this talk page as it is collected.

It is time to discuss color inkjet printing. Howtek, Inc patented and produced the first color Hot-melt thermoplastic ink printer. The inkjets were designed at Howtek by team of experts from scratch. The inkjet technology was the first drop-on-demand single nozzle tubular squeeze style drop generator type fundamentally invented by Steve Zoltan at Clevite Corporation in 1972 and investigated again by Exxon Office Systems in 1978 but rejected because of fluid instability from uncontrolled higher frequency modes (harmonics) and manufacturability. Howtek formed original glass nozzles and produced flat frequency response single nozzle jets in just 6 months. No two glass nozzles could be manufactured the same and molded nozzles were designed to solve the problem. No one had ever run piezo transducers near the Curie temperature until Howtek. Hot-Melt thermoplastic inks in four colors (CMYK) jetting on to paper, plastic or metal sheets was now possible. The Pixelmaster color inkjet printer printed millions of colors on each color drop location, precisely on top or each other or fractionally shifted over a drop, any combination of CMYK drops to achieve the color for that pixel. The Howtek color printer patent stated it printed colors in layers of different color. Layered printing from a digital data file that produces a three-dimensional article (having a Z axis) is by definition 3D printing. The inventor for the "Colored Printed Record and method" at Howtek is Richard R. Helinski and he is also the inventor of the 3D patent "Method and Means for Constructing three-dimensional articles by Particle deposition" a few years later after he left Howtek. This patent was licensed by Sanders Prototype, Inc which produced the first desktop 3D printer in 1992 and later by Stratasys and eventually by 3D Systems Corp on April 29, 2002. It is important to be clear that FDM and SLA 3D Printing technology is simply a coating of a single material, built up in layers, to produce an article. Few people understand inkjet 3D printing involves placement of uniform volume drops in precise locations and spacing along each point of a vector line. It is not a coating for a full layer of an article. Each point (drop) is treated as an individual article and adjacent articles (drops) fuse together to make the layer much like molecules form matter. It could be described as complex 3D printing in contrast to a coating layer or simple 3D printing. Sanders 3D printing has article boundary lines printed slowly for better edge quality and perimeter support boundary material to protect the article. There are 19 or more different printing line types that can be printed on one layer. The next 3D layer above prints and the next until the full article is complete. The inkjet ink material defines the drop spacing and proper volumes for each drop location. Inkjet 3D printers require jetting calibration before each article is printed. No other 3D printer verifies a unit article for proper mass per area. The Howtek 'single nozzle" style inkjet still exists today in one 3D Inkjet printer. The little Howtek style inkjet designed to print one sheet of text now is challenged to print articles that are frequently measured in hours or days in 3D printers using similar Thermoplastic inks.

Minor edits
Hi James K McMahon! I noticed that you recently marked an edit as minor&#32;at 3D Printing that may not have been. "Minor edit" has a very specific definition on Wikipedia – it refers only to superficial edits that could never be the subject of a dispute, such as typo corrections or reverting obvious vandalism. Any edit that changes the meaning of an article is not a minor edit, even if it only concerns a single word. Please see Help:Minor edit for more information. Feel free to let me know if you need help, I'm still fairly new but can help point you in the right direction. Retswerb (talk) 03:00, 28 November 2020 (UTC) I'll bs sure not to check that box again. A minor Edit is a typo error. Sorry about my mistake. Historian and Godfather of Single nozzle inkjets (talk) 14:16, 7 December 2020 (UTC)
