Hi,

One additional point: Try to print the calibration sqare in the middle of the printing area. If it works, you are on the right way.
The temperatur window is very small i think.
Try with following settings and important good refreshed powder:
Chamber temperature : 145
Surface temperature : 171, 7
Speed 550
One other...
Nice to hear :-)
I am still fighting with the right temperatur. I tryed to print 2 Fischertechnik bricks with a lenght of 9cm. With the temperatur setting of the fan duct i got warping.
The folliwing values were...
A thermal camera will be useful. But i have no one....and they are expensive to rent.
Here best print it is 10.5 cm long, but not so high. Pinter with 149,5 171,5 and speed 550. The small side...
Yes you are right, the uneven temperatures are a big problem. Front of the door seems to be the coldest position. And the right side is the next coldest postion. Then the left side and at last the...
Thank you for your effort. The print look very good. Yesterday i tried to print it again with significant higher powder surface temperature (174). And yes the print was ok, too. In the past the print...
Thank you for your advice. But for me it is most imported to know you do it. Perhaps you can share all of your printing parameter and the position where you print it.
Yes i am searching for better endstops. But it is not so easy. I have contacted the distributor who sell them to Sintratec. It is a German Company and it is easer to get new one directly. The problem...
Ok i will raise the temperatur a little bit more and try again....
The enstopper will not work because some powder or polymere get into the endstop and work like an isolator.
Do you see a little...
In conclusion you think it was a good idea to lower the temperature or to raise the speed?
I agree to your scaling issues. I have the same problem, but it is not so importent for my to solve it....
I tried you proposal. Yes it make a diference of the packing dense. Do you have sometimes warping issues which cause the print will destroyed? I print with following parameter:
Chamber temperature...
Hi Mike,
the reason why i do not have any support any more is very simple.
1. I bought the printer second hand and they will not give any support for these people. This was a new decision of the...
They make it true. I have no access to the support Ticket-system any more. Now i am not able to report bugs or ask questtions to the support. It is a very interesting behavior of the company.
Yes,...
ok very interesting. I will try.
Yes, you are completly right. You are able to see, that you will need more and more powder. As Sintratec told me i am able to see that sintered area is brighter than the not sintered area after a new...
In general my printer works fine. Right know i have a problem with printing large objects. I want to print an area of 10cm * 10 cm. It is not possible to rotate the object. The first 3 layer are...
Hi Mike, nice to hear that you are very pleased with you printer. Hey, i was lucky that i am able to visit the company. But it was a stony way to reach this printing results i get now
Do you have...
After this post the situation has changed a little bit.
Sintratec has invited me to come to Brugg and helps finding the problem. I accepted the invitation.
It was a nice day at Brugg. It was very...
I am not sure anymore.
Yesterday i got an unhappy mail that Sintratec will not support me anymore, because i bought the printer second hand.
They give me the choise to pay for the support 150CHF...
When you prepare the print with the software the lights will go on. Use the key to shut down the laser and open the door. I think than will see it and you can play with the position
yes this is important:
The frontal light shade has to be adjusted correctly. the shade of has to be aligned exactly to the backside.
You remember the L-Peaces near the lamps. The L-Peace of the...
i think the most importent thing is that you have an object that you could measure. Try to get first a nearly good print and than try to adjust the x,y,z. With the grid have an orientation. Try the...
140 C for the chamber is definitive to less. The shrinking of plastic happen at a specific temperature. The chamber temperature has to be highter than this temperature. With every layer you cool down...
