The original base started discoloring and delaminating in under 900 hours of use—the top layer became really rough. When I replaced it, I noticed the screws were also a bit loose. After the swap, it’s almost perfect now.
The machine has been in use for a year and a half, with about 2,500 hours of printing time. I bought a replacement thermal insulation plate a month ago but kept procrastinating on installing it, thinking the original one could still hold up. Recently, though, the first layers of my prints started coming out uneven, and I knew the original synthetic stone plate had finally given up 😂. So, I decided to replace it.
The removal and installation process is pretty straightforward—it only took about 10 minutes to finish. When removing the original plate, make sure to clean the back of the hotend and the mounting base thoroughly. Any debris left behind might prevent the new plate from sitting flush against the base. I recommend using cleaning gel or nano tape to pick up any particles—a brush works too, but be sure to hold a plastic bag underneath to catch the debris.
Whatever you do, do NOT use compressed air to blow the area clean. Don’t do it. Just don’t. And don’t ask why… let’s just say my hand feels kinda itchy now 😂.
This silicon-based product has no drawbacks; it's the perfect solution. Whether it's insulation, high temperature resistance, mechanical strength, or appearance, it's the best overall. Also, everyone must not use ceramic ones—those are for H2d, fixed on H2D's metal structure, so poor ceramic insulation doesn't affect H2D. But A1's fixing base is plastic, so the insulation of this product is extremely important; it affects the lifespan and precision of the tool head. Rather buy the original synthetic stone that breaks quickly than use ceramic ones. Of course, using this silicon-based one is currently the best solution.
Purchased it, installed directly on the new machine to avoid having to replace it later.
Replaced the 900-hour A1, and I'm feeling great now.
