Use this 2 Part Epoxy Coating to achieve a stronger ABS part.

TC-1614 A/B is an unfilled high solids content epoxy resin system. It is designed to seal porous to semi-porous substrates developing remarkable strength. As the penetrative depth increases the TC-1614 A/B also has exceptional adhesive characteristics and is capable of continued use at temperatures up to 350°F. It can be used at temperatures up to 400°F intermittently.

Popular infiltrant sealer for FDM parts and other 3D printed technologies.

Goal: Strengthen ABS part and give it a glossy finish.

Tools

  • Gloves
  • Printed Part
  • 2 Part Epoxy (A & B)
  • Plastic Cups (x2)
  • Weight Scale
  • Thick Plastic Bag
  • Coat Hanger
  • Plate (to catch dripping)
  • Oven

Steps

Step 1: Print part out (ABS preferred)
Step 2: Once cooled off, remove part and do any last-minute clean up

Step 3: Pour solution A into one cup and measure the weight

Step 4: Pour solution B into the other cup and measure the weight.
NOTE: In terms of weight, there should be twice as much A as there is B. Also, when weighing the solutions, don’t include the weight of the cup

Step 5: Pre-warm both solutions up to (90-100)F or (32-49)C. This helps lower the viscosity and cover your part more easily.

Step 6: Pour both cups into the thick plastic bag and mix. (Double bagging may be useful if you have a thin plastic bag (large Ziploc)

Step 7: Place printed part in bag and mix with the solution. Make sure to cover your entire part. Allow the part to soak for 20-25 minutes. This allows the epoxy to seep into the porous material.
NOTE: You can also paint on the epoxy.

Step 8: Remove printed part and hang it to let it dry.
NOTE: Drying in oven (100-120)F or (37-49)C , with a plate below to catch the dripping excess solution will dry the epoxy more quickly.
