3D printed circuit boards using conductive ink

The thought of using a 3D printer to fabricate PCBs is┬átantalizing and the good news is that it’s a reality. This project shows that it’s possible to use a special printer head to apply traces to an extruded substrate.

This is similar to the point-to-point 3D printer circuits with one big upgrade. Now the traces can be printed directly onto the ABS using conductive ink. The process starts with the design files, which are used to model a substrate that has a trench for each trace. A Makerbot then prints out this model. Once complete, the ABS extruder head is swapped for a special ink head. Each trace is then filled with the conductive fluid, which is kept in place by the trench walls until it can dry. We think this improves on the trace printing techniques we’ve seen before because it doesn’t require your printer heat to use molten metals.

The circuit above uses printed traces for the high and low side of an LED circuit. It’s a bit rough at the edges, but it shows a lot of promise. Don’t miss the demo video embedded after the jump.

  1. It’s hard to sit him down and rest. He probably needs rest. Sometimes that could be good and sometimes that Rayban Wayfarer Sunglasses could be bad. The published data indicates that the most common drug related adverse events in the study were diarrhea (19 in 100mg bid group, 12 in the 150mg qd group and 3 in the placebo group), upper respiratory infection (15, 7 and 7 respectively) and neutropenia (6, 7 and 1 respectively). Hypertension (BP>140/90) occurred more frequently in fostamatinib treated patients than placebo (29 across both fostamatinib groups compared to 17 in placebo group) as had been previously reported. The hypertension generally occurred within the first few weeks of therapy and was responsive to conventional anti hypertensive medications.This is intended to be a list of helpful hints that you may find useful when feeding adults with physical or mental disabilities. My experience is from the viewpoint of speech language pathology (SLP). Feeding is more properly within the scope of practice of an occupational therapist, although SLPs and nurses may also work on feeding issues.

"The idea that biologics could prove effective against autoimmune disease has been firmly established by the tnf story," says Dr. H. Michael Belmont of the Hospital for Joint Diseases in New York City.
