Compositum ABS ST™

ABS materials are dedicated for industry and professional application in close chamber FDM 3D printers. ABS ST™ material compared to the ABS EX™ is characterized by increased melt flow and greater flexibility. The great flexibility of printed models allows it to be used in the production of thin-walled components subjected to alternating bending, electronic housing components etc.
 
ABS ST™ filaments are marked by excellent cohesion of layers and very low linear contraction (up to 0,4%). Thanks to it the difference in mechanical properties of the printed sample compared to the model produced by the injection method is only 8%.
 
The ABS ST™ filament, as well as the entire Compositum filament family is characterized by a low emissions of volatiles and very low absorption of moisture, thanks to that the moisture absorbing substance is no required.
The strength tests performed on the printed samples represent real strength values of the material, obtained by FDM spatial printing.

 The output parameters of the control samples:
- filling: 100%
- layer: 0.2mm
- nozzle: 0.4mm
- print temperature: 240°C
- platform temperature: 100°C
- Temperature of the working chamber: 54°C

While using ABS ST™ with open chamber 3d printers, it is recommended to use side panels to stabilize the print temperature and reduce thermal stress.
During printing, the printer should not be exposed to drafts and the room temperature should not be less than 23°C. Do not use high-volume or large-volume prints. Do not artificially accelerate the cooling of the print by venting the print chamber or turning on the fans.
 
The best values ​​and strengths of high-volume and large-volume prints are obtained with closed-chamber printers with a temperature inside at the level of 45-55°C. After printing, wait until the temperature of the chamber is no more than 30°C. Do not artificially accelerate the cooling of the print by venting the print chamber or turning on the fans. If you are using adhesion spray wait untill the printout detach from bed.


Recommended print parameters:


Head - 240-250°C

The nominal print temperature for ABS ST™ material is 240°C.
Temperature range of 240-250°C is due to the various print head designs and temperature measurement inaccuracies. It is the average value of trial printouts for 10 types of 3D printers.

On some low-budget open printers with a Y-axis sliding bed where the hot-end is clearly overheating, the printouts are even made at a preset temperature of 220°C.
On a closed printer "professional in the manufacturer's opinion" the hot-end clearly did not heat up the material. For correct printing, the hot-end temperature was 270°C.
Attempts were made on 3 types of fully enclosed printers, 2 types of partially enclosed printers (open at the top), 2 types of printers with the possibility of mounting side panels with side panels removed and side panels installed, and 3 types of full-open printers. All available on the polish market.

No print cooling - all fans off.

Heat-Bed - Adhesion and temperatures
Table with 3mm thick glass glass heated by heaters glued on aluminum plate.
- Heat-Bed covered by substance causes an increase adhesion - Recommended: C-Stick™ Adhesion Spray: 90-110°C
- Heat-Bed covered by pad - Recommended: Coropad™ Adhesive Pad: 80-100°C.
 
Directly heated-bed using a heater stick to the glass.
- Heat-Bed covered by substance causes an increase adhesion - Recommended: C-Stick™ Adhesion Spray: 70-90°C
- Heat-Bed covered by pad - Recommended: Coropad™ Adhesive Pad: 65-85°C.
 
Other types of heated-bed should be individually adjusted for heating.
 
Too low bed temperature causes unsticking printout cornes.
Too high bed temperature causes yellowing bottom suraface of model.
The actual temperature of the table depends on: the point of temperature measurement, the thermal conductivity of the material from which it was made and the measurement accuracy of the temperature sensor.


Tolerances:
Diameter tolerance: +/- 0.03 mm
Oval tolerance: +/- 0.01 mm


Weight tolerance:
Bottom - 0.05 Kg
Upper + 0.10 Kg


Practical notes:

Print Quality - Tips.
- The side surface of the print with mat shade, clearly defined layer indicates an unheated material - possible cracks. Raise the hot-end temperature to achieve the effect described in the next section.
- The side surface of the print with a slight gloss of the layer, slightly scratched indicates the correct temperature of the material. No print cracks.
- The side surface of the print of the glossy print, layers is blurred indicate overheated material. Reduce the hot-end temperature. No print cracks. When printing on open printers at the top with side panels to minimize cracks, you can slightly overheat the material. Not recommended printing on fully open printers.
 
Glass heated-bed - In order to obtain a flexible layer before applying a substance that increases adhesion, you can coat the bed with a coat of hairspray (the "LIDL" brand called CIEN CLASIC - the color of the pink packaging is best). The use of a hairspray reduces the wear of the adhesive preparation and produces a flexible layer that makes it easy to peel off after printing.

 
Explanations:

ABS EX™, ABS ST™, ABS AT™ materials differ:
- Young modulus specified in the tables as "Flexural Modulus". This parameter is the basis for the selection of material depending on the expected usability and strength of the print.
- Parameters of workability of printouts.
- Applicable to recommended types of printers.
- Temperature of print work.
- Other strength parameters.
