Just to show what I am making and hot selling .

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 !

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 !
