DimaFix

Dimafix® is a fixative spray designed for FDM/FFF 3D printing technology with heated bed in order to eliminate the effect "warping". It is considered "intelligent" because its adhesion properties varies depending on the temperature used in the base of the 3D printed.

When ascending the temperature of the printer dock, Dimafix® adhesion increases. Using conventional lacquers fixed parts present deformations of up to 100 times higher than with respect to the pieces fixed with Dimafix®. Therefore, Dimafix® has a binding properties up to 100 times more than conventional lacquer, thereby minimizing deformation ("warping") printed in large parts or materials with many internal tensions. It has been tested successfully in materials which tend to warping effect as ABS, Nylon, FilaFlex, Polypropylene, HIPS, PVA, etc.

There are four temperature ranges differentiated based printing, which conditional adhesion power Dimafix®.

Then a graphic where you can see the power of adhesion Dimafix® depending on the temperature range shown.

• Rank 1: Temp.<65°C. Zone self-off of the part. Adherence within this temperature is very weak.
• Rank 2: 65 ºC <Temp.<75 ° C. Average adhesion area. From the 65 basic temperature starts to Dimafix effect. In this temperature range it is recommended for simple parts without sharp edges or complex geometries.
• Rank 3: 75 ºC <Temp.<95 °C. High adhesion area. You can print any type of geometry, especially those based not exceed 200x200mm.
• Rank 4: 95 ºC<Temp.<120 ºC. Maximum grip area. You can print any type of geometry and dimensions. In this range the bonding stress of the base of the 3D printer with the workpiece is high, withstanding any stress concentration factor.

Another advantage that Dimafix® provides with respect to other conventional lacquers is that after printing the printed piece off automatically descend again to the temperature below 40C. It is also easy to wash the glass base as Dimafix® is soluble in water. Usually, each pot 400ml Dimafix® usually lasts for more than 100 uses.

The following graph can be seen as from the base temperature 50 °C significantly increases the adhesion power.

Then tou can see in the following two reviews videos of fixer spray Dimafix® for 3D printing.
