We are getting close to the end of 2019 and we know all of you want to get IVI on hand soonest, and this is our wishes as well. It has been two weeks since our last update, we wanted to gather more progress to show you, but the interval is better to be short. Long waiting for an update is not expected. We were worried that you may be disappointed after seeing such a small update with little achievements. Usually, a satisfying result will be more welcomed than a piece of an insignificant process filled with difficulties. Considering a timely update is what you expect, we’d like to shorten the interval as we can. Below is the summary of recent work:
1. The delivery of newly-designed parts
To achieve an ideal precision, we optimized the 3 key components related to movement: print head, extruding device, and universal joint. We mentioned that we didn’t receive all the newly designed parts on time in our last update. It turns out the supplier was unreliable, even the first cooperation went well. We ended the cooperation and then chose 2 new suppliers to finish the parts, 1 for backup. All the new parts from new suppliers were received & inspected and then we applied them to the prototypes. The below pictures are the components we assembled with the newly designed parts. They consist of 42 small parts. From the perspective of user experience, these new components are preciser and stronger judging from the design, material and processing technic. The testing plan of the printer functionalities will be resumed this week.

Old extruding device (Left) V.S. New extruding device (Right)
Old universal joint (Left) V.S. New universal joint (Right)
2. Component Testing
We designed and set up a testing device to test the below items: contact point of the print head, auto-leveling, weigh, fan, heat sink, and ceramic tube heating. Also, the testing of these components is about to start this week.
3. Structural design and exterior design
The structural design was 90% completed and the exterior design was completed 80%. We plan to confirm the design by this week and then start producing 2 new prototypes.
Besides, we picked 5 molding factories out of 10 factories as alternative suppliers after site inspection. Next, we will make the final choice after the second round of selection, and this is planned to be finished before the delivery of new prototypes.
Ⅱ. Electronic hardware & software
1. Electronic hardware
A. The design of the ARM A7 control board (Related with LCD) is finished and started prototyping;
B. The fourth version of the motion control board is verified functionally and the trial production of 30 pieces is about to start.
C. Based on the newest structural design, we redesigned the power PCB and switch PCB and started prototyping. Now we are waiting for the delivery of the sample PCBs.
The main functions of ARM A7 (Related with LCD) were achieved and testing will be started this week.
Ⅲ. Words in the end
So, the above is what we’ve done in the past two weeks. Every task has lots of details to be considered. You may ask when will be the final shipping time, or if there is a new delay. We agree that it is better to be informed for changes earlier so that we can modify the established plan effectively based on the newest status. However, we are sorry that we cannot give you a clear answer now. If there are changes that will affect the ultimate timeline, we will synchronize the timeline and announce it as soon as we can. Thank you for your support as always.
