3D printing
Hi, I reverted your edits at 3D printing because it seemed to be promotion with no reliable sources. Wikipedia is an encyclopedia so articles are based on what other sources say about you, not what "you" say about yourself. I would suggest reading the basics listed above and looking at the Wikipedia home page for sister projects. Some of those are there for self published material.

Managing a conflict of interest
Hello, Rcrumpf. We welcome your contributions, but if you have an external relationship with the people, places or things you have written about on Wikipedia, you may have a conflict of interest (COI). Editors with a conflict of interest may be unduly influenced by their connection to the topic. See the conflict of interest guideline and FAQ for organizations for more information. We ask that you:


 * avoid editing or creating articles about yourself, your family, friends, colleagues, company, organization or competitors;
 * propose changes on the talk pages of affected articles (you can use the request edit template);
 * disclose your conflict of interest when discussing affected articles (see Conflict of interest);
 * avoid linking to your organization's website in other articles (see Spam);
 * do your best to comply with Wikipedia's content policies.

In addition, you are required by the Wikimedia Foundation's terms of use to disclose your employer, client, and affiliation with respect to any contribution which forms all or part of work for which you receive, or expect to receive, compensation. See Paid-contribution disclosure.

Also, editing for the purpose of advertising, publicising, or promoting anyone or anything is not permitted. Thank you. MrOllie (talk) 21:25, 1 August 2021 (UTC)

Please do not add inappropriate external links to Wikipedia. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include, but are not limited to, links to personal websites, links to websites with which you are affiliated (whether as a link in article text, or a citation in an article), and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the page, please discuss it on the associated talk page rather than re-adding it. Thank you. MrOllie (talk) 21:31, 1 August 2021 (UTC)

Please stop your disruptive editing. If you continue to add promotional or advertising material to Wikipedia, you may be blocked from editing. Constant314 (talk) 21:32, 1 August 2021 (UTC)

You may be blocked from editing without further warning the next time you use Wikipedia for promotion or advertising, as you did at Electromagnetic wave equation. Constant314 (talk) 21:34, 1 August 2021 (UTC)

 You have been blocked indefinitely from editing for abuse of editing privileges. If you think there are good reasons for being unblocked, please read the guide to appealing blocks, then add the following text below the block notice on your talk page:.
