After 3 years research my custom design 3D printer (for small items)

Here is my K800 3d printer , oh , no , it is my custom design 3d printer , I played hard on it . So the looking is 100% changed . More stable and more powerful .

Typically : 

  1. Remote fan and able to change as big power fans . light weight and same speed as Kossel mini or even faster .
  2. high power air heater to maintain inside temperature , 80 Degrees Celsius is tested ok . So any FDM material is ok .
  3. Able to print in small / accurates / detailed models.
  4. heated bed included , easy to maintain

haha , so many functions , I will keep on developing .

Super big delta style 3D printer is made !

Hello , everybody !  I silence for a long time and seems disappear , in fact , I am designing a big machine : Huge delta 3D printer ,

my hugh big 3d printer -1

 

When I talked my thoughts to friends , every one think I am crazy , it is impossible to work with such limit funds support , I insist on it this time because I saw other one is successful .  After months and months , day and night install & test , until today , it works !!! ( I feel I am luck , I almost give up …  
:-p )

According my test, max diameter 800mm is OK  (I think it can reach 1 meter square , but I make small mistake on design ) , and max height 1500mm is possible , ( I think it can be 1700mm , but I make another mistake too ) , the material can be PLA at present , I really hope to make ABS and other later .

It doesn’t matter ! the most important thing is , it works at the beginning  !!!

About the building progress , it is really not easy :

1. I have to find a big place to prepare , at last I throw away a table in my office .
2. I have to find the long aluminum support , very long and hard to take back , I paid a lot in extra express fee , but at last , I have to take it by myself , I put in on my arm and walk thousands of meter !
3. I have to waste lots of time on designing structure and waste some money at the beginning too .
4. I have to climb ladders by myself and tight each screw .
5. I link wires by myself , some is too long , some is short , have to joint together .
6. I burned electric board twice ! what a pain !
7. My huge 3d printer bed design is totally wrong , I waste a lot of money there and I have to give up whole design .
8. Crazy adjustment is behind ,  I spend of leveling for at least one month !

I think I can write a big book for eating such stuff one by one .  Now , it start work as I expect ,  I will publish more info later ,  Thanks the god ! and have a good day , everybody !

I have assembled Kossel 800 3D printer

Although is not good looking , at last I spend half month to assemble it as attached picture . photo_1410054984156 -1   At the beginning , no help from manual , because the designer is lazy or busy to create the manual for us , he just give us the guide to reference Kossel Mini !!!  So all the customer form a group to discuss and solve problem by themselves . So when install the frame , in fact I assemble wrong, have to disassemble 2 – 3 times again during install electrical part . At last , about 1 – 2 weeks I finished installation of frame and electrical parts , helped by our Kossel 800 seller group . But when setup software and calibrate the machine , we meet trouble again . Our talent team found a special way to calibrate by manual instead of unused G29 auto calibration . We can print now . Here is the calibrate test picture . 1409982550819 -2   Do you notice the tiny wire drawing , yes , it is not the perfect , but after create models , it is easy to remove by knife . If try to remove it during printing , we have to adjust slice software parameters at computer side . Anyway , I have not much time waste on it , I just hope to start printing lots of models , skip it now . microMsg.1409819279310 -3In order to backup the plastic accessory ( designer’s plastic’s quality is not good and some start to crack .) , I print some spare parts . Then I hope to print bigger toys for my daughter , I start to meet big headache . ( A common issue for FDM printer )  , Model edge cock ! 1410486306305 -4   Above pictures means I lost some model because of edge cocking . When printed Inverted triangle models , plastic material is easy to deform , the edge is probably raise then kick off the printer head . My score is : Lost three big model in one day .  It says that ABS is more headache on edge cock than PLA too ! Our strong Victims team create a method to lighten this issue , add a D9 pc fan near the printer head as below picture . Just hope when material comes out , D9 fan can cool it down faster to reduce edge cock ! IMG_20140913_113109 -5   Printed a special model to install the fan . Now I am printing big model again , hope that it works ! Finally I have to say , custom Kossel 800 is not easy to play , but it is interesting , it attract me to waste time and money on it now !

I booked Kossel 800 3D printer

As I research market more , I notice more and more people jump into trading feild in China , good products are always sold out but poor design products are hard to find customer however paid for advertisement . I start to feel that I should step into product development field , or sooner or later , I can not provide a good products .

Firstly I studied 3D design software : Rhino 3D , which is mainly design for shaping . ( I have no interest to study Pro/E or Solidworks , because those mainly face to molds . I would rather place my design to technician rahter than I involve into the deep sea of molding .

Secondly , I booked the cheapest and still said good quality 3D printer : Kossel 800 , some weeks ago , it is just about USD250 shipped , FDM working method , but able to revise the length / height , or even upgrade as laser cutting machine , CNC machine , PCB printer easily . Another reason is I notice this machine is created by a Chinese talent whom is carefully for his products , his previous products are all good remarks , so he should be a good boy to create Kossel 800. Here is a big picture to show Kossel 800 3D printer .

kossel 800 parts list -1

Until today , I have waited Kossel 800 3D printer for some weeks , some one got the machine yesterday because he booked earlier , he print a gift for his daughter , the 3D output seems good enough .

kossel 800 first output -2

The Kossel 3D 800 printer’s design and quality should be up to the market’s FDM commercial 3D printer , the difference is just in what material it use . It says that if poor material is also OK , just the model because ugly , have to polish by yourself .

OK , just some days left the machine will come to me , I will upload more news about it .
