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 . )
It 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 .
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 .
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 : China Rabbit 3D scan and 3D print
A local customer send me a blue China 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 .
I 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 !
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 !
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
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 !
