The dividing line of "tangentially off topic" is typically when the actual subject of the question being asked is only coincidentally adjacent to 3D printing. Here is a clear example illustrating the "tangential issue:" I printed a crane mechanism in 3D. How much voltage must I apply to the motor to lift 150 grams? I see this type of thing all the time....

Yes - in some cases. First, overlap between sites is fine. It doesn't matter if a question is on topic somewhere else; that's no reason to eliminate it from a different site's scope. There were some issues when HSM sprang up, because Mathematics, Physics, and other sites allowed history-related questions. I participated in several meta discussions on these ...

Yes, I think such questions should be on-topic.

Yes, such questions should be on-topic. There can be partial overlap in sites' scopes, and unique legal issues involving 3D printing can be addressed here. Users of this site are more likely to have specific expertise than users on a site that deals with laws more generally.

I would go with NO, as that should be dealt by law experts from the Law SE, instead of 3D printing engineers and enthusiasts in this site. Dealing with such questions in this site, would lead to the following problems, like wrong and unreliable advice. So, such questions should be migrated to the Law site, IMO.

I would say that they are on topic because it seems more reasonable to look for questions about the legality of 3D printing on a 3D printing site than a law site.

Various proposals covering the 3D printing space went through many iterations including a broader site about "Personal Manufacturing" and another for "Digital Fabrication." This is another variation on that scope. 3D printers are going to become increasingly capable and integrate features we haven't even imagined. So as 3D printers start to cross over into ...

I pondered this question a while ago and tried to come up with a coherent and minimalistic strategy. This would be my suggestion, as to what is on-topic or off-topic: So, basically, on-topic would follow the formula: (formingMethod == additive OR substractive) AND (instrument == machine) Off-topic would have the formula: (formingMethod == transformative) ...

I'd say that repair questions are more on-topic than construction. And if construction questions are okay, then repair questions should be too. An example format might be: How do I repair {X} I've tried {a[]} to fix {X}, but {b[]} occurred. What are some other common means of fixing {X}? Most of what is acceptable on SE is troubleshooting and I feel that ...

A quick reply for now (I might expand on it later). Please see Game plan - What is on-topic?. I've been trying to build a list for the On-topic page. I can add your suggestions to that list, if you like. Although CNC is already added to the list, but foam cutting isn't (yet). There were some questions asked about polystryrene cutting in [chat], from here ...

I like the expanded definitions, but there is probably an issue with some of the things you'd put into "just rough around the edges" portion of what you state. For instance, "Print Services" are mentioned as far as on-topic and what is allowed. To what extent are Print Services on-topic and allowed? In and of itself, as you've stated it, it could be ...

I have updated the on-topic page which some further explanations that came to mind, as well as some hopefully not to wishy-washy small print. The points below have been spliced into the on-topic page in (hopefully) the appropriate places. If anyone has any other suggestions of further expansions to the explanations of the new on-topic topics that they feel ...

Please look into this question, which is a similar question as you ask. I think the general consensus is that CNC and laser cutting machines fall in the same category as 3D printers with respect to control, axis, modeling, etc. as the difference may be the tool the positioning head is carrying. My general concern is if you want to include this, does the ...

The question was migrated because the specific question of "How do I tell if my Thermistors are 10k or 100k?" is going to be best answered by users of Electrical Engineering SE. This also provides the SE network with more appropriate traffic based on the question at hand. However, if the question of "How can I change the thermistors settings in Marlin ...

I understand 3D printing as a specialized topic of CNC. To extend the community other topics like mills, lathe or even punching turrets seem a good option to me because: They all relate closely to the same techology: CNC control, axis, CAD modeling, G-Code, etc. It would extend the possibilities of this SO page, which seem to struggle to get questions. I ...

It is worth noting that the question referenced in the OP deals with a vacuum forming machine, which isn't (similar to) a 3D printer by any stretch of the imagination. It heats up a sheet of plastic so it melts, which is then formed (using a vacuum applied from below) over a model. This just allows you to make copies of an existing model. If we want to ...

I believe all of these machines essentially are 3D printers with a different tool! As far as I know, you will often end up using both the same software and electronics as with 3D printers, and many questions can therefore be directly related as well. There are even several commercial "Multi 3D printers" that can do several of these functions. Then again, I ...

There is a new question on Meta that should help define what is okay on this site. However, your question is important to address here. Ultimately, you shouldn't be afraid to go ahead and ask the question. If the question does not meet the conditions of the present site, the general public will be sure to let you know and (hopefully) help direct you in at ...

I am going to strenuously advise against using this format for resolving what should be considered on topic for this site. I can appreciate the desire for decisive action and expediency, but it would seem untenable to tell someone their question is off topic because only the top {x}-voted subjects were deemed on topic, while {x-1} didn't make the cut. You ...

Mechatronics More specifically, question relating to electronics, mechanics and control theory which is set in a 3D printing context. Why include: There are multiple questions about 3D printing that also could be asked in the electrical and mechanical engineering sites, as well as the robotics site. However, since most 3D printers basically are desktop ...

Bio Printing As previously brought up in Meta, questions related to Bio Printing should be within scope. Appropriate questions related to Bio Printing include (but aren't limited to): Questions about the technology processes. Specified by the printing method (ie FDM). Questions about material specifications. Questions regarding troubleshooting of Bio ...

A couple of points: Asking for a machine to solve a specific problem, or software which can do something 'specific' is not really a shopping question, so long as the question is asked in the right way. We do need to avoid subjective questions, but sometimes this can be the result of a misunderstanding (i.e. find me a non-CN supplier of this budget Chinese ...

Thank you for bringing this up. I think that there very seldom are any good questions that ask for printer or software recommendations, and I would therefore vote for them not being allowed in general. So far I have handled these types of questions by waiting to see if other users flag them, and then take action after a close vote has been made. If we ...

Asking for which type of extruder is used by this assembly is on-topic, where to buy (shopping) is off-topic. This is discussed in this question. Another question that points out the differences between "shopping questions" is still unanswered but discusses differences between shopping questions. Some can still be answered based on how they are formulated. ...

I've taken onboard StarWind0's points and added them to the on-topic page. See this meta answer to On-topic has been updated - finally!. Regarding the question itself it ended up needing the fourth vote and got re-opened. I'll add an IANAL type answer at some point. I agree that it would be more suited to Law, and its generic nature could actually be asked ...

My perspective is this is more of a "is it illegal to buy illegal things" is not exactly bound to 3d printing. Though I still read those related to the operation of printers, IE the legality around printing dangerous things such as firearms and their parts is unique to the 3d printing and fabrication spaces. Honestly I feel that any legal questions should ...

I propose that we add Direct Ink Writing (DIW) and Melt Electro-Writing (MEW) to the list of on-topic subjects at https://3dprinting.stackexchange.com/help/on-topic Direct Ink Writing: Direct-Ink-Writing (DIW) is an extrusion-based additive manufacturing method heavily utilized in meso- and micro-scales. In DIW, the liquid-phase “ink” is dispensed out of ...

I don't think the question should be migrated. For EE.SE, the question is just stupidly obvious. Even a fairly inexperienced lab tech. would know how to go about answering that question. It really isn't an electronic engineering question at all. Here, the answer (assuming the question is actually the question that the user needed to ask) would be 'buy the ...

I think your situation fits for many new users on this site, and saying that "easy" or "semi-defined" questions are discouraged would probably turn you - and many others - away from the site. Rather, I believe it is the community's job to help you find a proper scope for your question. As long as you follow it up, edit and improve your questions according ...

No, such questions should not be allowed. This site deals only with the practical issues of 3D printing. Questions about legal issues should be redirected to sites dealing specifically with those, since users of this site do not have the expertise to address legal issues. A 3D printing expert does not make a legal expert.
