Most 3D printers have comparatively small construct volumes for 2 causes. First, standard designs require that the body be bigger than the construct quantity, so that you want an enormous machine to get an enormous construct quantity. Second, 3D printing is gradual and print occasions are instantly correlated with half measurement on FDM/FFF machines — with the square-cube regulation in full impact. However Emily the Engineer has by no means let practicality cease her earlier than, so she determined to construct a 10-foot-tall 3D printer to churn out towering components.
Even a really quick 3D printer would take an absurd period of time to print one thing that tall utilizing typical settings. However it’s potential to shorten that point to one thing extra affordable utilizing two strategies. Printing in vase mode solely lays down a single outer perimeter per layer, which signifies that a single layer can end as rapidly because the printer can circle round. That retains the layer time down. To scale back the variety of layers, Emily geared up the printer with an enormous 1mm nozzle that extrudes 0.5mm thick strains. The usual is a 0.4mm nozzle with 0.2mm layers, so this setup cuts the variety of layers down by 60%.
This challenge began as a joke and Emily did not need to put a giant finances behind it, so she began with an previous Creality Ender-3. She then changed the 2 upright items of aluminum extrusion with a lot, a lot taller items. The brand new items had a special profile, so she needed to design and print new rollers to suit.
Emily meant to drive the Z axis with threaded rods as lead screws, however rapidly discovered that they had been far too unstable at that size. So she transformed the Ender-3 to a belt-driven Z Axis utilizing KevinAkaSam’s design. With a firmware replace to alter the printer dimensions, Emily was prepared for a take a look at run.
This tallboy 3D printer labored. Although, predictably, the half wobbled perpendicular to the Z axis and that brought on high quality points. Wider components had been extra steady, which mitigated that drawback. With that in thoughts, Emily determined the printer wanted a bigger mattress that may permit for wider components. So she rebuilt the printer to attain that.
The outcomes are fairly spectacular, particularly for a bed-slinger. This printer can, certainly, produce respectable super-tall components. However there are large drawbacks: the components must be very huge and printing in vase mode signifies that they’re fragile. Nonetheless, that did not cease Emily from printing an enormous Amongst Us character for laughs.
