I'm aware I cannot ask for recommendations and I'm not interested into. But I'm looking for a specific feature of a 3D printer and since my primary language is not English I'm not sure which is the correct word (or words) to describe such a feature.

My question would be like this: "I'm looking for an enclosed 3D printer that allows to load a common 1 kg filament bobbin. Do these bobbins rely on a specific standard? How to filter out the printers that match my request when making a Google search?"

Is this question acceptable for you?

  • $\begingroup$ In general, I don't think this sort of question would have the problems that come with recommendation-type questions. (Recommendation questions tend to be very subjective in terms of what the best product is, and also tend to be time-specific in that product availability/prices/etc. often changes over time.) That said, whether it'd be a good question and whether the community wants to allow such questions may be a different matter. $\endgroup$

1 Answer 1


Part identification is on topic

We have had questions about what the specs for a motor were, we had some about replacement parts.

Spool sizes are on topic

Bobbins, reels or spools have almost standard sizes, because manufacturers buy them in bulk from China. Typical sizes I found looking on Alibaba (a website that connects manufacturers and wholesalers) are 0.33, 0.5, 0.75, 1 and 3 kg, most feature the same outer diameter but different spool widths, which allows easier packing. If there is a standard for those would be totally on topic.
