Can you promote in r/advanced_3dprinting?
Advanced 3D Printing – Beyond the Usual Layers Topics include: - Custom G-code - Experimental printing techniques and workflows - Unusual or challenging prints that test hardware, materials, or creativity - Slicer workarounds, data-driven printing, or artistic printing methods Whether you’re fine-tuning your firmware, generating toolpaths by code, or just trying something wild with your printer—this is where it belongs.
The short answer
Post technical, value-first content (demos, methods, code, G-code snippets) with clear disclosure of your affiliation and minimal promotional language; include detailed setup and safety notes.
What works here
- Sharing projects, tools, slicers, firmware, plugins
- Posting demos, G-code snippets, technique write-ups
- Explaining why a tool/method is useful with technical detail
- Disclosing affiliation when applicable
What gets posts removed
- Spammy posts, clickbait, or link dumps
- Pure advertising without technical value or explanation
- Hiding affiliation or failing to be transparent
- Low-effort posts that belong in beginner subs
Where this comes from
View the current official rules on RedditSelf-promotion allowed if it adds value
Rule explicitly welcomes creators/developers to share projects/tools as long as they contribute to the community and explain usefulness.
Transparency required
Affiliation must be disclosed when sharing your work or tools, which mandates clear disclosure of vendor/founder status.
Technical detail expected
Posts should include useful details (printer setup, materials, code, process) — founders should lead with technical substance, not marketing.
No spam or link dumps
The rules forbid spam, clickbait, or link-dump behaviour, so promotional posts must avoid excessive links or salesy content.
Safety & experimental content guidance
If hardware or hazardous experiments are involved, include safety notes — useful when presenting novel tools or materials.
