That was what the last comments mentioned, but the topic was closed before an actual resolution was formed. That was also just the first post I found with a simple search of this forum for “Grey V4”. There are other similar posts that are out there referring to quality issues with V4 however all formlabs responds with is that they have tested it and it works fine. Even after admitting that V4 has a problem with foaming.
When can we expect to see the next iteration of Grey?
