[Video] No Oxygen tank ! Dreamlike sexy mermaid dive show under 10 meter water

On last Sunday I brought my daughter to visit the big shopping mall in Guangzhou , we didn’t buy thing , we went to the “Ocean Park” (Yes , the Ocean park is inside the shopping mall !!!)

At first , I had thought the park is small or even tiny , doesn’t has many animal , but at last I feel I am wrong .

It is a medium size Ocean Park and there are still interesting fish / creature there . But the most amazing show is : Dreamlike sexy mermaid dive show under 10 meter water , and No Oxygen Tank support at all !

I can not say how beautiful it is ,,,  just take the video as above . ( Slow network here , I spend whole day to upload !!!)

Good to share everywhere in the world .

Sorry to late publish this video because I didn’t touch Premiere for a long time to link those video clip together . If you are in GuangZhou now , call me to go there !  :-))

[Video] Use Grasshopper Firefly to connect Servo or Stepper motor

Long time not to appear , I suppose no one like to research such thing except me !

So how to control arm bot from computer side ? ( arm bot installed Servo or Stepper ) ,


I don’t like to use Arduino #C , because it is really hard and complicated . At last I feel Grasshopper + Firely is the best .

In the beginning I use Servo , it is pretty easy , just the Servo is too poor , it is not accurate at all . Here is the video .

Another video .

But when start to write ,it is poor looking , because the Servo is too poor  .

So at last I try to use Stepper to try , here is the 1st stepper to test in Grasshopper firefly .

Then I install it on my arm bot , For cost reason (Actually it is because of my poor wallet) , I use 28BYJ , the smallest and cheapest one .

First test after installation , notice I have revised the stepper motor by manual , it is tough looking . haha~

But at the beginning , there is a big issue , and I almost give up !

it is lucky that I resolve it . Here is another success small video.

Wow , is that smooth moving ?  let’s zoom it out !

I spend some months to make such thing , it is really waste time , but I love this hand-working-and-research .

Upload this article , just hopes the world won’t forget my efforts .

Recently i am trying tiny product’s 3d print

I think the huge 3d print development should stop to wait more funds to throw into…

These days i get some inquiry to print small things. For example : little statue , Jewerly, watch back cover . They require small 3d print and beautiful surface like SLA +/-0.1mm .

Occasionly I test 0.06mm layer height by my huge 3 meter 3d printer , just print some rings, it is surprised that it works ! Here is pictures.

IMG20150929172733 -1 microMsg.1443001960478 -2 mmexport1442832141145 -3

Such thing encourage me to revise my small kossel 3d printer to print Jewerly . Now I have finished design new printer extruder , it seems improve quality.

These days I will try to revise the frame , i have purchased linear bearing , this revision should be hard works, hopr that everything will be fine later .

I hope final resolution can reach +/-0.02mm or even same as SLA +/-0.01mm . Revising the small machine these days .

3D Print big model of respected Bruce Lee statue

Long time to “dive into sea” for a long time because of many study plan and working .

Today  I announce that my Big delta 3D printer is able to print 800mm diameter & 1.5 meter height of many things . Such as : Bruce Lee statue which is successful to print one month ago . ( Sorry I am too busy to update instantly . So my Huge 3D printer is OK to work and accept design from oversea .

Here is the pictures of progress of stumble :

See some trouble on head of shoe ? My fault on slice parameter  !

IMG20150708173953 -3

Fixed by some putty to adhere temporary . Go on printing .

Start to leg , but I meet trouble soon ! After I used out 1 roll PLA material , I start with new one , but notice there is color difference .

IMG20150718093311 -6

IMG20150718105656 -7

Poor PLA vendor didn’t take any responsibility for that , so i had to go on and forget this vendor forever !

Almost waist , the model start to shake … I use a chair to stable it !

IMG20150805174613 -10

Chair is not enough , now to support start to shake , I try to use glue , help a little only .

IMG20150730125005 -11

Trouble comes one by one and fix it by hand slowly .

IMG20150730125033 -12

microMsg.1439004031547 -13

That is because of poor material ! At last I found it . Later I decide to use another vendor’s material , so color change again .

IMG20150814115157 -14

It is stable now , everything works good !

OK , 3D print big model is not an easy job , I got lessons this time .

600mm length model was printed by my huge 3d printer

I get a demand from boss’s friend , he hope to print an object for a car . Wait 1 – 2 weeks until his engineer send me the 3D design artwork , but their UG poor designer create a bad model , can not use in Solidworks as well as 3D slice software .

Later he output files as *.stl , then I start to print . The first challenge is to level / adjust my huge 3D printer’s bed , I waste about one week to adjust step by step , and I found my 3mm aluminum ground seems not smooth . ( But it is still OK to try . )

firstlayer -1It is lucky that I succeed in one time , no need to adjust any more . After waste some hours printing , I notice the support’s density is too much , waste time and money , so I stop the Huge 3D Printer , and re-create the slice gcode . I joint it carefully and it looks no difference in model appearance . Here is final looking of the printed model .

Is it fine enough ? Each layer is 0.2mm .

Going to 3D print a bar light (beer pouring)

I just get an interesting stuff for coffee / cafe / bar , a special design lighting base , just put on a LED light and bottle and turn it on , as long as put on the table at night , it will be attractive .

At present I only have semitransparent color PLA , it looks white color only , if have customer ordered , I will buy other color material .

3D print can do almost any shape , I will keep on studying it .

Four rabbit 3D print and surface treatment

As my customer want better looking of 3d print rabbit , I feel pressure on surface treatment . Just force myself to do it !
Firstly I printed four white rabbit .

image -1

Then started to try to polish surface to make.it smooth , i tried tools, paints , spray , muds and chemical method .

At last , l tested a lot, it seems only muds might be good .

Here is mud cover then polish looking .

image -5

another one use spray gold color.

How about paint and spray ?

Please notice i was sending 3d print samples to my customer .

Surface treatment is a hard and complicated works . I need to put more time on it to research .

First project : Ceramic Rabbit 3D scan and 3D print

A local customer send me a blue ceramic rabbit as attached picture , he request to copy as 1/2 size , 3d print to him for reference , I am thinking he should use it to make as toys .

blue rabbit (1) -1 blue rabbit (2) -2I am the first time to handle such stuffs , you can see the reflection on rabbit body is big , most of 3D scanner can not scan reflect items like metal , glass , liquid etc., I try to find ideas from scanner maker , it is lucky that they just find out a solution to scan . See below pics , I am scanning the blue rabbit !

scanning rabbit (2) -3 scanning rabbit (1) -4

Rabbit is set on the round plate , which is able to rotate 360 degree by hand or electrical power ( motor inside ) , use a special design portable hand-held 3d scanner to scan , I suppose they use Kinect technology and enhance it . ( For some reason I can not display that 3D scanner here , but it is not expensive ! )

After scanning , there is still some stuffs on 3D model , I have to use Geomagic to remove it !

IMG_20150402_131020 -5

Now , it cover with wooden texture , looks like better .

Then I spend whole day to adjust 3D printer parameter  and print it .  Here is the final pictures .

The white 3D rabbit is 0.2mm layer height , speed about 70mm/s , 210 centigrade extrude heating .



Huge delta 3d printer challenge Eiffel Tower model for test

huge 3d printer test eiffel tower -1

No matter whom has a 3D-printer , people finally like to challenge the hardest model to see if their 3D printer is good , so do I .

The 3D printing mainly parameters are : 0.2mm layer height , 60 ~ 70mm/s which is already several times more than those X-Y-Z 3d printer in local market . ( I don’t like to use 30mm/s like them , it is certainly not my research direction .

I spend some days on it . At first , I buy some turbo fans , print retainer and tight it on effector ( some fans threw away ) , and I adjust the parameters to reduce extruded drawing issues , then test other small models to evaluate if my huge delta 3d printer is good enough , finally I decide to change to use the best PLA material I can find locally , although it is expensive , I hope it helps .

Some one separated the model for 4 pieces because model is quite big , but when I slice the biggest one , my poor computer almost can not stand  ( what a big model !!!), I test the smallest part ( top part first ) , the effect is amazing , but the extrude speed parameter is low , 3cm base is broken , later I have to use “Breakpoint continue” technique to joint .

the 2nd part ( count from top ) is easy , I don’t meet any troubles,  but the 3rd part slicing software has trouble , one unexpected layer appear , whatever I try , it is there , it seems the model has small issue . Then I keep on printing .

The 4th part is the biggest , and waste 10+ hours , when printing on Railing , I notice this part is extreme slim , a small mistake might cause wholly failure , I change the printing speed and extrude volume immediately to avoid troubles , so the tower railing is there , not like those poor machine , railing is disappear at all . 🙂 When grows up , the structure become horrible , each place is almost point to point print , In order to be faster , I am crazy to raise the speed to about 70mm/s . ( As I thought , poor printing structure is hide inside , unless you split my model , you won’t see it …

Finally , I glue four parts together and here is some pictures . I feel satisfied on my huge delta 3d printer , if speed is slow , it is accurate enough to print anything as long as it is big , and it is stable to bear hours hard printing . But I also notice my expensive PLA material seems Stickiness is not enough , so I have purchased other expensive material to wait for test later .

Huge 3d printer is not easy to handle , I put lot of times to taste how it is , hope that people will like it and give me some supports on orders !
