How it looks
Looks like the seventh Duplicator version 1.3 is simple. The cover is heavy, metal. The case is black, on the front panel of the logo and the switch, there are gaps in places - in the photos you can see where the case is visible when printed. Coolers are constantly working, they make noise.
According to the manufacturer, the device differs from v 1.2 in a large number of fans inside. We did not disassemble the case, but - judging by the noise, it is.
The platform low position sensor is red, it is needed for calibration - this is the zero position. Below the platform can not fall.
On top of the course of the platform is limited by a lid on the guide, this one - on four screws. The manufacturer’s information states that from version 1.1 there was also a software lifting limit, but it isn’t - the platform holder rises to the stop. Either the restriction was removed, or it does not work.
The screw seems to be weak, they write about it in all reviews of this printer - they write it correctly, it does not cause trust. But it works.
This version has a switch on the front, on the next one it was removed back. On the one hand - so that someone does not turn off the printer during printing, on the other - to simplify the layout.
How it works
When you work, the computer must be constantly turned on, if it falls asleep - a breakdown in printing, if it restarts, too. Take care in advance to turn off all energy saving features and automatic updates.
A bath of an original design - instead of glass and silicone a film is used, which is tightly attracted by 22 bolts to the frame. Changing the film is easy, but tiring. Big plus - it is cheap.
Brand photopolymer manufacturer arrived not gray, but of an incomprehensible pale yellow color.
Experiments have shown that if, after washing, we put the printout into the water and then expose it, it becomes light gray, almost white.
If you just rinse in isopropyl and put it under the sun or lamp - the color remains yellowish.
The photopolymer smells strongly, if you leave a stamp for the night - in the morning it is impossible to enter the room, it is necessary to air it.
Impressions and Recommendations The
printer looks simple, in both senses: in the good - concisely, and in the bad - cheap. And he justifies both impressions.
The functional is almost zero. Yes, it shines on the polymer and lifts the platform, i.e. - performs its main function, but it is tightly tied to a permanent connection to a computer. Failure to connect - marriage. No battery life from a flash drive or card. Automatics thrown to the maximum.
On the other hand, with its price, the D7 is the only available stereolithographic printer for those who cannot pay ten times more. It is far from the accuracy of Form 2, but, within its characteristics, it justifies itself. It is only necessary to provide him with an uninterrupted connection to a PC, the only job and specialization of which will be the print on D7. The kit with the computer will be five times cheaper than a separate printer with a higher class.
Whether to buy Wanhao Duplicator 7
D7 can not be recommended to dentists and professional jewelers - its accuracy is low for these applications.
But for home builders, makers, inventors and artisans, it will be useful, as well as 3D printing enthusiasts who love to improve their technology themselves - the printer has a great potential for rework and sufficient margin of safety to sustain them.
