Design 1 Fabrication

This page will go over the steps to create Design 1 of the PDS.

Step 1:

Begin by printing the .STLs for three-part mold that are found on the Downloads page. Print 1x design1_core.STL and 2x design1_outer.STL. Supports are not necessary for printing.

Step 2:

Assemble the mold with the two outer pieces surrounding the inner core. Put the two clamps around the mold.

Step 3:

Measure out 25ml of Part A and Part B of the Ecoflex 00-30. Put both parts in a cup and mix together thoroughly with a spoon.

Step 4:

Pour the mixed Ecoflex into the mold slowly and steadily and stop occasionally to let bubbles escape. Fill the mold to the brim. Let the silicone cure for 4 hours.

Step 5:

Once the Ecoflex has cured, take the clamps off of the mold and use a screwdriver to pry apart the mold. Pull the cast off of the core.

Step 6:

Attach the lengths of 1/4" and 1/8" tubing with the luer fitting.

Step 7:

Insert the 1/4" end of the tube into the open end of the silicone cast. Secure a zip-around around it and tighten it into place, securing the tubing.

Step 8:

Connect the 1/8" end of the tube to the pressure sensor on the electronics.
