I just received my H2D. On my other bambu printer I have always loved the PEI Smooth Plate. I am sad it is discontinued for the H2D. I have been experimenting with the Engineering plate, but it requires glue. I feel like I am gluing the plate incorrectly/unevenly as my most recent print had some adhesion issues one small area.
The texture of the engineering plate seems to be making it difficult to apply liquid glue. The plate seems to be scrapping the pad of the liquid glue applicator. I am even starting to see some wear and tear on the glue pad after only a few uses. The glue stick doesn’t glide very smoothly. I saw some old posts about applying water and wiping the plate after applying glue to make the application more even. What has been your most successful way of applying glue to the engineering plate? Do you wash your plate and apply glue after every print?
Can I ask a fundamental question: Why are you using the Engineering Plate?
As the name suggests, it’s actually designed for a very specific type of filament that needs to be heated to a high temperature. Optimized for high-temperature filaments.
If you’re using standard filament, like PLA, PEG, TPU, etc., then Bambu Cool Plate SuperTack Pro should actually be the right plate for you, especially if you’re coming from the smooth plate.
…or simply buy an equivalent alternative to the smooth plate from a third-party manufacturer.
Do you have a filament that’s so specialized that it absolutely requires the Engineering Plate? Using the other plate means that you can avoid using glue altogether, or at least reduce the amount you need.
So, once again, the key question: What kind of filament do you actually want to print? Maybe you’re using the wrong printer plate for the job.
At least this question can already be answered:
Yes, you have to do that after every print. It’s not primarily to make the filament adhere better - even though it’s called glue - but as a separation layer so you can remove your printed object more easily without damaging the plate.
In this case, the glue is not actually a adhesive, but rather a release layer. By the way, another drawback is that you end up with residue from the adhesive on the surfaces of your 3D print. So, once again, what kind of material do you actually want to print?
