With regard to resin and exposure times:
1- Resin Types: it is important to know the specific characteristics of the resin used with our
printers and the different factors affecting it, taking in account the technical note "Our resins"
(in the folder "Resins" in the DVD supplied with the printer).
2- Basis Exposure Times: the exposure times of the bases are very important, in order to obtain a
perfect adhesion of the object to the Construction Base of the printer, and then a good printing
result. In most cases we can recommend for bases, a time value from 6 to 9 seconds, whereas,
if the base is large, the value that should be inserted will be lower, but if the base is small the
value may be higher. We want emphasize that if the exposure time, assigned to the base of
object, is too high, it could trigger a suction effect between the Construction Base of printer
and the Siligel, with the risk of ruining this one. To prevent this effect it is very important to
observe the print of at least the first 5-6 layers, paying attention to the correct movement of
the vat during the printing. If any issues occur, you have to stop immediately the printing with
the button "Stop Printing", then decrease the exposure time set for the base, clean the
Construction Base of the printer and restart the printing.
In general, for test printing (first 10-15 Layer) we recommend an average setting, is around 7
sec. for the base. After test printing was interrupted, check that the base will be attached
permanently to the Construction Base of printer, if there is not good sticking, slightly increase
the time (input the time to 7.5 or 8 sec), if there is too much sticking (suction effect), slightly
decrease the time (input the time to 6 or 6,5 sec).
3- Layers Exposure Times: as regard the object layers (upper the base), the exposure times can be
set to a value from 0.6 to 1.3 seconds. In the test printing (first 10-15 Layers) we recommend an
average setting, is around 0.7 sec. After test printing was interrupted, you have to check that
were built the first layers of every support, if some support not is constructed, slightly increase
the time (input the time to 0.75 or 0.8 sec).
4- Examples of printing: to better understand the points above is recommended to follow the
explicative examples in the chapter "Using of management Program" in the manual
"Installation and use of the program".
With regard to cleaning:
At the end of printing, we must proceed with the finish of the printed object. The operations are few
and simple, but must be conducted with special care to ensure the proper preservation of the object
or, if it is used for investment casting, for the success of the lost wax process:
1- Preparation: Put a quantity of Isopropyl Alcohol (or RF Cleaner - CL01) to cover the object in
Ultrasonic Device.
2- Removal: With the metal spatula, remove very gently the object printed from Construction
Base. Caution: Use the metal spatula putting pressure frontally, not on the edges (otherwise
you may chip the glass).
3- Ultrasonic Device: Place the printed object in Ultrasonic Device, for cleaning of the same from
any excess of not solidified resin, and activate the device for not more than 2 minutes,
otherwise the object surface can be damaged. If the cleaning liquid is recycled and with resin
