Should you upgrade your Bambu lab P1P to P1S 3D Printer?

You may already have read my review of the Bambu lab P1P 3D Printer, where I point out the good and the bad. In that review I mentioned the P1S upgrade kit, which I’ve now had installed for a few weeks and wanted to share my experience about.

What is the Bambu lab P1S upgrade kit?

The upgrade kit is much more than just an enclosure. It includes Air filtration, heat management for the control board and chamber, auxiliary part cooling fan and of course a door and lid.

It also comes with an upgraded cable chain that increases performance and reliability.

It essentialy turns your P1P 3D Printer into a P1S 3D Printer, so you don’t have to buy a new one.

Why upgrade to P1S?

The P1S, with it's enclosure and chamber temperature management is much more suited for printing “engineering” materials that otherwise tend to warp. It’s also much more stable in performance depending on where you have your printer.

For those printing in a cold garage or attic, this helps manage temperatures, and therefor reducing warping.

It’s not automatically better for printing abrasive materials, for that you also need the hardened drive gear and nozzles.

How good is it?

I noticed quite obvious difference in my ASA prints. I printed just before the upgrade and just after to avoid any moisture buildup or other enviorment changes. These materials still wants to warp, so adhesion is key. I’m just using the Dual sided textured plate from Bambu Lab and nothing fancy.

The “generic” profiles for ABS and ASA also includes “too much” part cooling, making my test part, that is very prone to warping, to still warp a bit.
When you change these settings to lower or no cooling, it’s much better.

Here’s a few examples.

I hope these images gave some clarity on improvement out of the box. There is obviously more tweaking needed, and maybe another type of build surface for perfect adhesion.

I’d also like to thank Lndnny at Printables.com for their design that I used as an example.

I’m for one very happy with more quite and less smelly printing!
