Hello everyone! UK based lost foam enthusiast here. Ive taken a lot from this forum over the last year and so thought it was time I share some of the things I have cast with all that help and information! See some pictures of various things I have built / cast below. I also have a query on casting with expanded polystyrene. I keep having failures when casting large pieces which are solely expanded foam and wondered if it was to do with temperature or the way in which I am feeding the parts. See next two pictures. These are the only photos that I have by way of explination, they were a test for a lamp base. I really like the bobbly texture and have been trying to use that as a feature. I have has success when using it in addition to XPS but when done alone I have had very limited success. The first attempt I realised that I needed to pour a lot faster than when using XPS. I then made some much larger pouring cups so that I could empty the contents of an A20 crucible into the cup before the sprue had even burnt away. No luck. I tried using a sprue made from the densest XPS I have. No luck. I tried a very very long sprue, a thin one, a thick one. Every time the part still only fills halfway / three quarters before collapsing in on itself. I have tried vibrating for 30 minutes solid. Feeding from lots of locations. etc etc. I cant really think of how else to approach it. Any advice welcome! Some bits in no particular order. Lamp - single piece casting. The shade is made by casting onto a piece of laser cut aluminium which took a fe attempts. Newish casting barrels. I have two, both with trapddors in the bottom for emptying / filling with forklift assistance. Two person lifting and pouring tongs for an A25, the largest crucible that will fit in my gas furnace. Copied / inspired by this forum. Really effective. I modelled up them up in Solidworks to get the correct tipping point. In use. Please excuse the lack of PPE. Some experiments with laser cutting XPS. And some sculptures. Both cast as single pieces. Top one measures about 350mm tall. The second one is about 600mm.
