![]() ![]() Supposedly this is Craborundum glass, so silicon carbide, which is normally used as an abrasive powder, and the only place I can imagine they’re using silicon carbide is in the coating, not in the glass itself. Sure, there are a few smaller details, but these two are the only ones that I think make a real difference.īoth now have this screen printed bed surface that does stick and release really well, but it is quite easy to scratch. Both of these printers have some drastic improvements over arguably Creality’s most popular machine, the original Ender-3, which we’ll get to in a second, but really, the only two noteworthy bonus features the CR-6 SE has over the Ender-3 v2 are auto bed leveling and a filament sensor. Of course, the fact that the Kickstarter preorders then weren’t exactly shipped on time and people who had bought a CR-6 SE outright after the Kickstarter actually got their machines earlier than backers, well, that one doesn’t sit quite right.īut that’s over, and today I want to actually compare the CR-6 SE to the Ender-3 v2, which has had a completely normal launch, you know, by just appearing in stores on day. And when people pledge almost $4,500,000 on the campaign, I think that shows that it was absolutely the right thing to do. Kickstarter are happily taking their cut of your pledges, Creality gets hype for their new product, you know, it’s good marketing. Now, sure, it’s not what I would call “in the spirit” of crowdfunding for a well-established company to essentially pre-sell a 3D printer there, and while they surely don’t need the preorder money to actually start production of the CR-6 SE, there’s nothing, like, legally wrong with it. Out of all the companies that would need crowdfunding to launch a product as basic as the CR-6 SE, I wouldn’t really think of Creality. This is a printer that was launched on Kickstarter by Creality – a company that has boasted about selling half a million printers in a single month earlier this year. Let me start out with the controversy that was the launch of the CR-6 SE. It’s more reliable, it prints better, it looks like a more professional machine, comes in 1/3rd cheaper and it’s a printer you can buy right now without having to deal with the entire crowdfunding or preordering thing they’re doing with the CR-6 SE. But here’s the thing: The Ender-3 v2 is their actual budget 3D printer and it is actually doing a much better job at just about everything the CR6-SE tries to do. It’s an attempt to catch up to the big boys and to finally have something that’s not going to be labeled as “just another budget 3D printer”. Learn more about the peer-reviewed research on Cr(VI).The Creality CR-6 SE. This draft IRIS assessment for hexavalent chromium is at odds with the findings of over 30 peer-reviewed studies, which support a threshold for effects and a non-linear, dose-dependent response. The IRIS program, however, has a troubling history of being out of step with the best available science and methods, lacking transparency, and being unresponsive to peer review and stakeholder recommendations. The EPA’s IRIS program identifies human health hazards associated with a substance. In October 2022, the EPA released a draft Cr(VI) Integrated Risk Information System (IRIS) assessment of oral and inhalation exposure for public comment. The EPA’s IRIS Assessment for Hexavalent Chromium ![]() See what various regulatory agencies have to say about hexavalent chromium here. The EPA, for example, has a drinking water standard of 100 parts per billion (ppb) for total chromium. The human body naturally detoxifies low levels of Cr(VI) into non-toxic Cr(III), no matter the source. Cr(III), also known as trivalent chromium, can also be naturally present in drinking water and is a micronutrient that is essential for metabolism. National and international regulatory agencies have set drinking water standards to protect the public from all forms of chromium (Cr(VI) and Cr(III)) in drinking water. drinking water supplies contain naturally occurring chromium. There are two potential sources of hexavalent chromium in drinking water – natural sources such as rocks, minerals, and other geology, and localized industrial runoff. Hexavalent chromium (Cr(VI)) is a form of the element chromium, which is one of the most abundant chemical elements found in the earth’s crust. ![]()
