Following the usual trend, “low-cost” printer and custom ink, this model has taken it a step further: A cartridge filament system interlocked with a throw-away print head. The design makes it convenient though, just drop in a cartridge and snap a head in place and go.
As can be seen in the first picture, there is a filament cartridge on each side and two blue print heads in the center. There is a sample head the left side. The heads just snap in place like loading an inkjet cartridge.
The strange black boxes at the rear corners triggered several questions in previous posts. They are simple mechanical retainers to keep the feeder tubes in place. There is a little blue ring on the tubes that snaps in place and it just locks it in position. I asked the design engineer and was told it is a prototype and they will simplify it. The whole top of the machine is actually a 3D print for the prototype.
The inside of the machine can be seen in the second picture. It has a usual heated build chamber. Note the big blower in the back with a wide horizontal slot near the top. The two white rectangular objects in the top center are the print head tips. They have what appears to be a silicone rubber cover.
The most intriguing part to me is the head design. It is extremely small!! Besides the thermal heater function it also has the drive circuit inside that small case. I managed to get an opportunity to look inside it. It is very nicely made, considering it is a throw away item.
· The filament is non-standard size: 1.3mm
· The drive motor is a low-cost brushed DC motor with what appears to be a simple magnetic encoder
· The motor is geared down with a worm-gear.
· The heater with the thermocouple is extremely small, about 6mm in diameter.
· There is a small PCB with an IC on it and a few extra components. Presumably it is the interface for the thermocouple, the shaft encoder, and I would guess an internal serial number to prevent reuse if someone manage to find filament that would fit.
