Can I post about my own scanning product here?
Yes, but only if your post includes at minimum an image of a unique scan created with the associated device so it carries some educational value.

Rule summary
- Be Kind and Respectful: Treat all members with respect and kindness. Harassment, hate speech, and personal attacks are strictly prohibited.
- Limited Advertising: Advertising or sale posts must contain at a minimum an image of a unique scan created with the associated device to give some educational value
- Stay On Topic: Ensure your posts and comments are relevant to 3D scanning.
- No Malicious Content: Do not post any malicious or harmful content, including viruses, malware, or links to unsafe sites. No blatant shilling for one manufacturer by disparaging another.
- Respect Privacy: Do not share personal information or images of others without their consent.
Works well
- A post showing a unique scan you made with your own device, with notes on how you captured it and what you learned
- A detailed critique of a specific scanner model or app, backed with concrete details that explain every claim
- A question about scanning technique, settings, or workflow that invites practitioners to share their experience
- An educational walkthrough of a scanning project from capture to finished model, with images of the scans
- An honest comparison of two scanners grounded in scans you made yourself, without disparaging either manufacturer
Avoid
- Posting a blanket criticism of a company or its products with no supporting details, which gets the post deleted and the account banned for three days first and forever if the behavior continues
- Criticizing a specific scanner or app without the details that explain your assertion
- Advertising or selling a scanner without including an image of a unique scan made with that device
- Shilling for one manufacturer by disparaging another
- Sharing scans or images that show other people without their consent
- Posting links that lead to unsafe sites, malware, or viruses
What r/3DScanning Is For
This is a community for people who share insights, ask questions, and stay updated with the latest trends and innovations in 3D scanning. The people posting here are scanning practitioners, hobbyists, and buyers comparing scanners and apps. The description also sets a clear tone on criticism, so detailed critiques of a specific scanner or app are welcome, while vague complaints about a company are not. Everything posted should connect back to 3D scanning in some way.
Rules That Matter Before Posting
Five rules decide what survives here. “Be Kind and Respectful” bans harassment, hate speech, and personal attacks. “Limited Advertising” is the one marketers care about most, because advertising or sale posts must contain at a minimum an image of a unique scan created with the associated device to give some educational value. “Stay On Topic” means every post and comment has to be relevant to 3D scanning. “No Malicious Content” bans viruses, malware, and links to unsafe sites, and it also bans blatant shilling for one manufacturer by disparaging another. “Respect Privacy” stops you from sharing personal information or images of others without their consent. On top of the rules, the community description sets a criticism standard, so blanket criticisms of a company or its products with no supporting details get deleted and the poster gets banned for three days first, then forever if they do not improve.
What To Post
A good post here teaches something about 3D scanning. If you are a founder with a scanning product, the rule gives you the shape directly, include an image of a unique scan created with your device and make the post educational rather than a plain pitch. Show a scan you made, explain how you captured it, and share what you learned about settings, surfaces, or workflow. If you are reviewing or criticizing a scanner or app, name the specific model and back up every claim with details that explain your assertion. Questions about scanning techniques, comparisons grounded in your own scans, and honest writeups of your results all fit the description of sharing insights and asking questions.
What To Avoid
The fastest way out is a blanket criticism of a company or its products with no supporting details. That gets deleted, and the poster gets banned for three days first, then forever if the behavior does not improve. Criticism of a specific model scanner or app is fine only when you include the details that explain your assertion. Advertising or sale posts without an image of a unique scan created with the associated device break “Limited Advertising”. Blatant shilling for one manufacturer by disparaging another breaks “No Malicious Content”, along with malware, viruses, and links to unsafe sites. Harassment, hate speech, and personal attacks break “Be Kind and Respectful”. Off topic posts break “Stay On Topic”, and sharing personal information or images of others without their consent breaks “Respect Privacy”.

Common questions about r/3DScanning
Can I complain about a scanner that disappointed me?
Yes, if you name the specific model and include the details that explain your assertion. Blanket criticism of a company without supporting details gets deleted and can get you banned.
Are links to my blog or documentation allowed?
Yes, as long as they lead to safe sites. Links to malware, viruses, or unsafe sites are not allowed.
Can I compare my scanner to a competitor by saying theirs is bad?
No. Rule 4 bans blatant shilling for one manufacturer by disparaging another, so comparisons should stay factual and respectful.
Can I post a scan of a person I met at an event?
No. Rule 5 says you must not share images of others without their consent, so get permission or scan objects instead.
