The soda bottle air tank that everyone has been waiting for is coming! It is capable of continuous air supplying, safe and low-priced. After trying a bunch of different methods and going through a lot of materials, I found the best solution at last! Let us take a look at the series of changes!
眾人期待的空氣汽水瓶即將登場了,它可以實現持續供應空氣的機能,安全又便宜,我試了很多種方法以及材質,最後終於找到一個最佳方案! 來看看這一連串的改變吧!

The design concept of soda bottle connector differs from general design due to the coordination with 3D printing materials. For example, avoid using support material while designing components.
ver.1 (fig.1.) The connector is composed of a traditional cap and a washer. The airtight is incomplete and the cap could loosen up easily during movement. ver.3 (fig.3) A plug-shaped thingy is created, placed into the opening of the bottle, and fixed with 4 screws to keep the cap from loosening up.
ver4 (fig.4) Replaced the material of O-ring with silicone rubber and achieved 99% airtight. However, air leaks from the contact surface between PU tube and 3D printed part. Though the contact surface could be glued to reach 100% airtight, it causes a lot of trouble. Eventually, ver5 (fig.5) is able to keep all air pressure from the surface of 3D printed part by plugging the bottle with a cork (rubber stopper) and inserting a PU tube to achieve 100% airtight.
Airtight can be completed with 3 silicone O-rings yet, the contact surface between PU tube and 3D printed part wouldn’t be sealed.
Airtight can be completed simply with a cork, followed by a 3D printed part to fix it in place.
寶特瓶連接處為了搭配3D列印件,設計與一般的概念會不同,比方設計上零件避免也會避免使用支撐材料.
版本1(fig.1.)連接處為傳統的蓋子加上墊片,除了氣密不足,運動中容易轉開.版本3(fig.3.)將形狀往瓶口內塞,有如塞子的形式,並且用四根螺絲固定住,運動時不鬆脫.
版本4(fig.4.)將O-ring材質換成矽膠,達成99%氣密,但空氣會從PU管與3D列印的接觸面洩漏,可以用黏膠作為氣密,但是這相當麻煩.最終版本5(fig.5.)所有的空氣壓力不會與3D列印件接觸,方法使用軟木塞(像膠塞)塞住瓶口並且插入PU管即可完成100%氣密.

 使用三條矽膠O-Ring完成氣密,但PU管與3D列印件連接處無法密合 |  使用軟木塞即可達成氣密,並使用3D列印件來固定防止軟木塞移動. |
Fig.8. S-Path
(fig.8.) To improve the appearance, I created S-Path, a part that moves the air pump upward. Originally the part was 100% fill 3D printed, later replaced by pneumatic quick coupling connected with PU tube due to airtight problem as mentioned earlier.
(fig.8.)為了美觀,我設計了將打氣筒往上移動的零件,稱為S路徑,原本採用3D列印100%填充,不過一樣無法達成100%氣密,因此更改使用氣動快速插PU氣管.

The mechanism of cylinder rotation is powered by pulling the trigger. However, the rotation could be smoother. So far, I’m trying to fix this problem.The development of Mega tank has come to a temporary end. It’s time for cylinder. The below image (fig.10.) is a prototype in testing phase.
Mega tank研發告一個段落了,接下來是Cylinder了,下圖(fig.10.)是正在測試的原型,
利用扳機去推動Cylinder旋轉的原理,目前旋轉不夠流暢,目前正改進這個問題.

At the end, let’s talk about other things. First, during manufacture, filament often ran out without my knowing. Therefore, I installed an optical filament runout sensor. The alarm will be triggered if the filament ran out or broke, indicating the filament needs change or refill.
最後來聊聊其他的東西吧,首先是製造的部份,因為先前常常遇到filament沒了卻不知道的情況,因此安裝了光學斷線感測器,只要filament斷裂或是用完了,警報器就會響起,提醒必須更換.

Then, it comes to JSPB check valve 3D. The design concept is fairly simple. I hope that people are able to print their own check valve at home instead of buying expensive ones or ones that breaks easily. Simply print it yourself.
再來是JSPB CHECK VALVE 3D,這個的設計理念很簡單,希望能讓人在家裡也可以列印出來的CHECK VALVE,你不需要去買很貴或是容易故障的CHECK VALVE,自己列印就可以了.

JSPB check valve 3D is not yet completed though many materials and parts have been tested. So far what I know is O-ring and marbles are not applicable. After preliminary test, Nerf dart tip and cork seems to work and are ready for further testing.
JSPB CHECK VALVE 3D 目前尚未完成,已經測試過許多材質與零件,現在可以得知的消息是,O-ring不可用,彈珠不可用,Nerf彈頭與軟木塞初步測試似乎可行,正要進入進一步的測試.
This is my recent progress and development for the last two months. Thank you!
以上就是這兩個月的研發進度,謝謝大家!
