Build volume is only one variable. Material temperature, chamber control, support strategy, nozzle wear, repeatability and day-to-day throughput matter far more once the printer becomes an engineering tool.
The important split is not “cheap versus expensive”. It is open-frame prototyping, enclosed general-purpose engineering, and actively heated professional machines.
A1 through H2D, with the range separated by materials, thermal control, support strategy and build envelope.
Read the range guide →How to choose for brackets, housings, jigs and fit-check parts rather than display models.
Read the prototype guide →Throughput, failure cost, standardisation, material capability and whether one flagship is better than a small fleet.
Read the business guide →Same general footprint class, very different thermal and support capability.
Compare →When the enclosure is a genuine engineering requirement rather than an expensive convenience.
Compare →The 180 mm envelope looks close on paper, but the lost usable volume is much larger than it first appears.
Compare →When active chamber heating and a 340 mm build envelope justify the jump to H-series.
Compare →Product development rarely ends at one additive process. Resin printing solves fine-feature problems that FDM does not, while 3D scanning closes the loop from physical part back to CAD.
Printer selection, engineering resins, dimensional control and a clear decision framework for when resin is the wrong process.

Explore 3D scanning →A 350°C hotend does not automatically make a machine suitable for every 300°C filament. Finished-part reliability depends on the whole thermal system, material condition, geometry, bed interface and process control. Our guides try to keep those distinctions intact.
