If dimensional accuracy matters for your TPU work, the P1S is the printer to use. Seals, gaskets, custom enclosures, anything where 0.3mm variation ruins the function: the enclosed chamber fixes this. In an open room, temperature drafts cause flexible filaments to cool unevenly. That variance shows up as part-to-part inconsistency across print runs. The P1S maintains stable ambient temps throughout the print, keeping variation under 0.1mm for most 95A TPU grades. The direct drive extruder and Bambu Studio profiles are identical to the A1 Combo. You are paying for the enclosure's thermal stability, not better hardware. TPU does not produce meaningful fumes, but the HEPA filtration is there if you run other materials too. For hobbyists printing phone cases and grips: save your money, the A1 Combo is enough. For anyone producing TPU parts that need to fit precisely, repeatedly, the P1S is the right call.

The Ender 3 V3 SE is the budget entry point to actual TPU reliability, and the direct drive extruder is the reason it works where the older Bowden-equipped Ender 3 models failed. With direct drive, 95A TPU prints consistently when you adjust a few settings: speed down to 25-30mm/s, retraction at 0.5-1mm distance and 25mm/s speed, temperature between 220-230C, and fan off for the first few layers. OrcaSlicer's TPU profiles are better starting points than Creality's defaults. The Ender 3 community has documented all of this thoroughly. If something goes wrong on the V3 SE with TPU, someone on Reddit has already solved it. The honest expectation: plan for 1-3 calibration prints before a successful TPU job. That is more friction than the Bambu A1 Combo, and the A1 costs more for a reason. But once the V3 SE is dialed in, it runs reliably at a price where the trade-off makes sense for budget-focused makers.

If you need TPU to work every time, the Prusa MK4S is the machine. The Nextruder redesigned the extruder geometry from the MK3S specifically to handle flexible filaments better: shorter path, tighter tolerances around the drive gear, and geometry that constrains the filament through the melt zone more effectively. Fewer jams. More consistent extrusion. This matters most at mid-range hardnesses, 87A-95A, where the material is stiff enough to cause inconsistency but flexible enough to buckle if the path is loose. PrusaSlicer's TPU profiles are tested against specific filament brands including Polymaker PolyFlex and Bambu TPU-95A. They get updated with each firmware release. For rigid materials, the MK4S at 200mm/s is noticeably slower than the Bambu A1. For TPU, where practical print speed caps at 50mm/s regardless of machine, that speed difference is completely irrelevant. Open-source design also means community mods are available, including a silicone heater block sock that reduces TPU ooze on travel moves. The price is not cheap. But for production runs of flexible components where a failed print has real consequences, the reliability record justifies it.
