Makerbot Replicator 2x Silicone Heater Block Mold
Description
This is a mold to make your own silicon sock for the heater block on the replicator 2x. I recommend watching these two videos on the topic: https://www.youtube.com/watch?v=O5UiXky85hA&t=636s and https://www.youtube.com/watch?v=LIbQROgT8h0 I used this high temp rtv silicone: https://www.amazon.com/Permatex-81630-Ultra-Temperature-Gasket/dp/B08CRY2BJB/ref=sr_1_1_sspa?crid=230PA606PUGIY&keywords=high+temp+rtv&qid=1699300442&sprefix=high+temp+rtv%2Caps%2C120&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1 I used theses syringes: https://www.amazon.com/10ml-Syringe-Sterile-BH-SUPPLIES/dp/B07KQP69RG/ref=sr_1_4?crid=28YS5KQCREKSQ&keywords=syringes&qid=1699300751&sprefix=syringes%2Caps%2C142&sr=8-4 The molds are bolted together with 4 m3x20 bolts and nuts. I used Vaseline as a mold release and it did okay. I like the process outlined in the second video better. If I were to do it again I would use the soapy water technique and then place the glob of rtv, one inside the cope, one in the drag. Insert the core and squeeze them together and bolt it up. I would then follow up with the syringe to make sure there aren't any air bubbles. I highly recommend curing for 48 hours using this rtv. To get the mold apart there is a lip that can be pried apart. Do this slowly and help the silicone release with a pick. To get the core out I used a spatula to pry up from the "back" of the core and helped it along with the pick.
