What Heated Bed actually is
Bed heat improves adhesion and reduces warping for many materials. PEI sheets plus correct temps beat glue rituals for most beginners.
High bed temps need a solid PSU and a level, clean surface. Wait for heat soak on big plates.
Why it shows up on product pages
- Spec sheets and ads use heated bed as a premium or safety badge
- Buyers compare mid-range vs flagship partly on heated bed
- Support articles and unboxings repeat the jargon without decoding it
Buyer takeaway: Treat a heated bed as default for modern FDM — cool-only beds are niche now.
Choose it if / Skip it if
Prioritize Heated Bed if:

Stop paying extra for it if:
- You only dab tiny PLA minis on a cool plate successfully
- Budget is better spent on a more important spec for your use case
- You already own a workflow that makes heated bed redundant

Can firmware change this later?
Sometimes features improve or regress with updates. Check recent owner notes for your model.
