Hi everyone,

I’m looking to invest in a 3D printer setup for a small-batch production run (10–30 units per batch) that needs to run 24/7 in my bedroom. I need to move away from the "3D printed look" and achieve a factory-grade, weighted, and polished finish.

Technical Requirements:

  • Multi-Color Reliability: I need a highly reliable 4-color system for printing branding and high-detail components simultaneously.
  • Surface Quality (No-Sanding): I am looking for a "surgical" or "injection-molded" finish straight off the build plate. I’m considering "fuzzy skin" settings, variable layer heights, or specific matte filaments to eliminate visible layer lines.
  • Weighted Parts: Plastic feels too light for this application. I need advice on the best way to add physical mass (e.g., pausing prints to fill internal cavities with sand/metal shot or using high-density infill/wall counts).
  • Bedroom Safety & Noise: Since this is 24/7 in a living space, noise levels and air filtration (HEPA/Carbon) are my top priorities.

Machines I’m considering:

  • Bambu Lab P2S Combo: I’ve heard it’s the most "plug-and-play" for production, but is the build volume (256mm³) too limiting for batching?
  • Creality K2 Plus (with CFS): The larger build volume is attractive for bigger batches, but how does the "out of the box" surface quality and multi-color reliability compare?

Questions for the community:

  1. Which of these (or others) provides the most consistent, smooth finish without post-processing?
  2. For those adding weight to prints, what is your most efficient workflow for batch production?
  3. Is an enclosed printer with built-in filtration enough for a 24/7 bedroom setup, or is an external vent or independent air purifier mandatory for health?
  4. How do the P2S and K2 Plus compare specifically on noise levels during high-speed printing?
