The Comgrow T500 Puts 125 Liters of Build Space on Your Workbench

Why 500mm Changes the Math

Most desktop FDM printers cap out at 250mm on a side. That gives you roughly 15 liters of printable space. The Comgrow T500 expands each axis to 500mm, delivering 125 liters of capacity. That is an eightfold increase in volume, and it fundamentally changes what you can print in a single run.

When a model fits inside a 500mm cube, you stop splitting cosplay armor into five pieces. You stop gluing functional brackets together after printing them separately. A single-piece print is stronger, has no seam lines, and takes less post-processing time. For batch work, you can lay out dozens of small parts across the bed and walk away while the printer runs overnight.

What the T500 Actually Offers

The Comgrow T500 is sold through Sovol and ships with a 300C all-metal hotend, 49-point auto bed leveling, and native Klipper firmware. It uses linear rails on all three axes, which should improve rigidity and reduce wobble at the edges of such a large bed. The frame is built to hold the 500mm cube steady, but that also means the printer is heavy and demands a solid workbench.

The open-frame design leaves the print volume exposed to ambient air. That works fine for PLA and PETG, but materials like ABS or carbon-fiber blends need an enclosure to maintain consistent temperatures across that much surface area. Buyers should plan for the full cost of a large enclosure if they intend to push the machine beyond basic prototyping.

Who Should Buy It

The T500 makes sense if you regularly hit the limits of a 250mm or 300mm printer. Cosplay makers, prop builders, small-batch product designers, and engineers who need large functional jigs will fill the build volume quickly. At its current sale price of $499, down from $949, it is one of the cheapest ways to get a half-meter cube on your desk.

It is not a beginner machine. The footprint, the material requirements, and the time commitment for large single prints all demand more experience than a starter printer. If you mostly print small figurines and desk toys, you will never use the extra space. But if you have been chafing at build volume limits, the T500 removes that ceiling entirely.

The Bottom Line

The Comgrow T500 trades convenience for capacity. It is a big, open machine that prints big, single-piece parts at a price most large-format printers cannot match. Just make sure your workshop can hold it before you order.
