Hi Alex,

The kit is not difficult to assemble, just time-consuming. It actually goes together very easily as all the tools necessary are in the kit and the instructions are excellent. I will get...

I am now very happy with how the printer is working and it is producing some good parts. However, these parts are still not quite right dimensionally and this is where I am still confused as to how...

Hi, thanks to Roman and rudschul I am pretty close to optimal settings. I moved the shade back but it is very difficult to see where the shadow is and as I could not see it on the powder, I presumed...

Will just half of one degree make much difference when the temperature fluctuates more than that as new powder is introduced and is never very steady even when doing nothing? At 175C the first layers...

Now I am really frustrated. Two more aborted prints today:(. This time I loaded the print chamber with four of the test pieces, in a similar pattern to that shown in Roman's photo below. All four...

Interesting - Roman has just responded to a ticket I sent about the issue and he says the chamber temperature does not matter too much.

The first prints were done at the default values with the...

Hi Rudschul, colour of the powder is difficult to ascertain but it doesn't seem to discolour at all. I appreciate what you are saying about the warping and the difference in temperatures but I am...

Thanks for the reply Roman. Below is a copy of a ticket I have just sent regarding my test prints.

Printer is now operational and I have been attempting the test print. First print was not good...

Thanks fred, you are right that it does not make sense to fill the chamber if only making tests of small items. If I don't get a definitive answer from Sintratec, I will try with just a small amount....

Replacement driver and switch arrived today so I was pretty keen to get them fitted. Had to earn some brownie points first though before I could play:(. I first checked the driver was working by...

Well, it's taken five days but my replacement parts are finally on their way. Can't wait to get this thing fired up!! I have got quite a few things lined up to print as test pieces and a fair few...

Nicely said, rudschul - a strong community can go a long way to help alleviate problems and frustrations by owners helping one another. The supplier (Sintratec) can also get valuable feedback from...

Hi Roman, thanks for responding here, as well as on the ticket system:), it's good to know that someone from Sintratec is looking in on us now and again.

Hi rudschul, I am absolutely sure there is not a problem with the main electronics board as I have wired both the X and Y galvos from both outputs from the main board and both work fine when put...

Yes, bit of a bummer - there was no smoke so I am guessing it was faulty from the start. I have sent a ticket to Sintratec and will have to wait to see how quickly they respond. The time it takes to...

Further to my woes. It is now conclusive that I have a dead galvo driver.

I first swapped the power leads to both drivers to see if it was a power supply issue. No problem, power to both drivers....

Well, yesterday my missing parts arrived so I was keen to get them in and the construction finished. I double checked the wiring (yet again) and connected everything up and turned it on. So far so...

Interesting what you say about the screws becoming loose. I did notice that there were no references to any thread lock throughout the instructions which surprised me a little considering the...

Maybe they tightened up on tolerances because my kit lined up perfectly. I was quite surprised when I dropped the hat onto the core to see the leadscrews go straight through the bearings and into the...

rudschul, it is difficult to see the wiring in your picture of the lamp kit so I cannot compare it with mine. Mine has heat resistant, braided insulation on the leads and I have not used any other...

Agreed - the problem is when you want to experiment with different materials. It has been suggested that I go with a begging bowl to nearby, bigger sls businesses for a couple of kilos at a time. An...

Thanks rudschul & fred_dot_u for chipping in. Good to know about possible short circuits although my kit did come with, very long, insulated leads on the IR lamps. While waiting for the missing parts...

Hi,

I first saw the Sintratec kit at the Birmingham TCT show, a few weeks ago, and was impressed with both the machine and the group of guys involved with its production. I have just completed the...
