3D-ADD EK1 is our Electrically Conductive additive for 3D printing high conductivity materials for electronics e.g. antennas for IoT applications (HF, UHF), RFID and NFC tags, OLED, OPVs, flexible PCBs, flexible cables, etc...
It is a metallic beige paste which provides high conductivity to our 3Dresyns, after post curing them at relatively low sintering/curing temperatures. Typical values of 3D-ADD EK1:
- sintering/curing T=120-200ºC (the higher the sintering temperature the lower the resistivity) for 5-10 minutes after 3D printing:
- Resistivity <30 microohm centimeter (when used in dip coatings)
- Resistivity will increase proportionally to its dilution in any 3Dresyn
Features of 3D-ADD EK1*:
- easy mixing and compatible with any of our 3Dresyns
- expensive option since 3D-ADD EK1 will be in the bulk of the device whilst conductivity is just on the surface of any conductive material
- ideal for dipping 3D prints in 3D-ADD EK1 for cost effectiveness since 3D-ADD EK1 will be on the surface of the 3D printed device.
- adjust the viscosity of 3D-ADD- EK1 with our Conductive Thinner CT1 to control the rheology and the thickness of the 3D-ADD EK1 to wish when dipping the 3D printed parts inside it
- 3D-ADD EK1 has excellent adhesion on the surface of most 3Dresyns
- high conductivity when used in dip coatings: Resistivity <30 microohm centimeter
- low sintering/curing T=120-150-200ºC for 5-10 minutes
- non toxic
- long shelf life (c. 6 months in the fridge)
- broad sintering/curing compatibility: photonic, NIR, low vacuum oven, thermal curing, etc.
3D-ADD-EK1 is supplied as a kit, which contains 10 or 50 or 100 grams of 3D-ADD EK1, 10 or 50 or 100 grams of Conductive Thinner CT1, 1 measuring flask to measure exactly the volume of 3D-ADD EK1 and Conductive Thinner CT1 and 1 empty 250 mL black bottle to mix, keep and protect the blends.
Note: conductivity of 3D printed parts will depend on several variables, such as % 3D-ADD EK1 and the sintering/curing cycle used. LCD printers may exhibit printability limitations, due to their low light power, at high dosage of 3D-ADD EK1. It is highly recommended to apply 3D-ADD EK1 by dipping the 3D printed parts inside it diluted to wish with our Conductive Thinner CT1
