Obviously H2S CoreXY system has the precision benefit over A2L bedslinger system. I’m looking for production printers for large single material prints ( 330mm+ and PLA or PETG).
There are no noticeable accuracy issues between A1 mini and P1 series. My concern is that would not be the case between A2L & H2S because the part print size. Is dimensional accuracy an issue for A2L large prints like 330 x 300 x 150 prints? Would friction-fitted parts printed from two different printers fit? Thanks
No they don’t. That’s fundamentally inaccurate.
Your overall question is unanswerable, there are far too many variables to account for, including part geometry, material, material dryness, print settings, and the functional requirement of the friction fit.
If you print a 280x280 cylinder and a 280.1x280.1 ring gauge on EITHER of those printers I would expect the first one isn’t going to be a slip fit. Test printing and compensating to achieve desired fit is key.
The only thing I can point to as a possible difference is the benefit of a heated chamber to encourage dimensional stability - although depending on part geometry and material, that may not even be needed.
Real world physics says otherwise, especially on large prints.
Buy both. Try them out.
Buy more of the one you like more.
If you are planning to print parts with the slip fit requirement on different printers, your best chances to accomplish that is with the H2S as it allows the use of the vision encoder plate.
The vision encoder can correct skew and X/Y dimensional deviations without a lot of hassle.
If there is a slight skew in the A2L, you have limited control to reduce that, and if so, it would be a tedious process.
Still all other factors that @CarbonForge mentioned, are important also.
A2L print quality starts suffering as it reaches maximum height. BL can put as much damping and software compensation as they want, at the end you can’t cheat physics.
Since I’ll be printing edge to edge, large print warping on open frame is another concern. Now I’m leaning toward H2D, even thought I have couple of U1 already.
