This is a bit of a departure of sorts for the company, which up to now has produced only desktop-style 3D printers of much smaller size. The 3DWOX 7X, however, is a beast that sits on the floor and is considerably larger.
Like its siblings, the 3DWOX 7X uses filament extrusion as its 3D printing process, with 1.75mm filament format employed. The machine can print layers as small as 0.05mm, which is just about the best that can be achieved by most extrusion 3D printers.
The big change — other than the build volume — is that the 3DWOX 7X includes dual independent extruders. This is a more frequently found feature on some advanced 3D printers, but it’s still not on many machines. Now, the 3DWOX series includes it.
Dual extruders allow the use of two different materials in a single print job. Quite often this doesn’t mean simply using, say, two different colors, but rather one extruder is loaded with dissolvable support material. This allows the 3DWOX 7X to easily 3D print highly complex geometries with delicate elements. There would be no stress in removing support material as in other devices; no need to damage fragile components — the support simply dissolves away.
While dual extruders are quite useful, the 3DWOX 7X extruders are independent. This means the machine could potentially perform some interesting print job maneuvers, including: print twice as fast; print duplicate copies, print mirrored copies. We’re not sure which, if any, of these will be implemented by Sindoh.
The 3DWOX 7X includes a massive 10.1” color touchscreen for operational control. Its networking options include WiFi, USB and direct connect ethernet. Like all 3DWOX printers, there’s also an onboard webcam, noise reduction feature and a HEPA filter.
The big question many might be wondering about is whether the 3DWOX 7X must use proprietary material cartridges as was required by earlier Sindoh machines. The good news is that the 3DWOX 7X will accept “open material”, in much the same way as the company’s 3DWOX 1 machine.
Sindoh says the 3DWOX 7X will accept a variety of materials including PLA, ABS, Flexible, PVA (all from their own catalog), and PLA, ABS, ASA, PETG, PA and other open materials. Sindoh says they are also intending on providing print profiles for certain third party filaments, which should increase ease of use considerably. This seems quite powerful! The machine is able to accept 1kg spools, but might be able to fit 1.5kg spools depending on the machine’s final design.
