Prusa Community Live, September 2026 edition.

Tech/Product/Platform highlights (from the Prusa Community Live stream)

1) PrusaSlicer 3: workflow improvements for multi-material / multi-printer

• Discussion of Slicer 3 features showcased in a prior stream, including:
  • Multi-color / multi-material slicing
  • Multiple nozzle size workflows
• A major “life hack” emphasized by a host:
  • Multiple build plates within a single project (effectively enabling multiple printers/profiles in one job)
  • Example workflow: split a project by material—e.g., print PG parts on one printer/profile and TPU parts on another—while keeping everything organized in a single slice/project
• Benefit/rationale:
  • Avoids constant manual switching between printer profiles and bed setups

2) Prusa Connect / Prusa Link (local / self-hosted concept)

• They discuss desired capability to send all farm files “in one go”:
  • With Prusa Connect already set up on the farm side, uploading multiple files should automatically dispatch them correctly if printers are configured properly
• They also clarify/preview:
  • Local Prusa Link / “link” next generation concept:
    • Acts more like a local access point for devices
    • Prusa Connect becomes local/self-hosted on a local device (instead of web-hosting)
• Feasibility testing mentioned for home lab environments, such as:
  • Raspberry Pi
  • Containers
  • Mention includes Nomad

3) Slicer 3 plugins: “plugin marketplace” direction + feedback routing

• Hosts explain that VIP coding plugins (plugin development) has become easier:
  • Improved manifest/basic information
  • AI-readable documentation
• Feature direction:
  • An official plugins website planned to behave like an app store
    • Browse/download plugins directly into Slicer
    • Community voting/upvoting/downvoting
• Potential future expansion:
  • Similar sharing experience for print profiles and settings (more standardized distribution)

4) Alpha-quality guidance and where to report plugin/add-on issues

• Caution: Slicer 3 plugins/add-ons can be alpha and may break depending on the environment
• Bug reporting guidance:
  • GitHub is the ideal channel, because issues go directly to developers
  • Forums/Reddit are also mentioned, but GitHub increases direct developer visibility
  • Support may submit feedback on the user’s behalf
• What the reporting system helps with:
  • Tracking how many people hit the same issue
  • Crediting contributors who reported issues

5) “Back to school” promotions + product discounts (Prusa hardware/materials/education)

• Deals focus mainly on single-color printers, with bundled extras and Academy content:
  • Assembled Core One (Gen 2)
    • 2 PLA spools free (referenced colors: “Pristine white,” “Prusa orange”)
    • Includes free Prusa Academy course discounts and parts-related bonuses
  • MK4S pricing
    • ~20% off assembled
    • ~10% off kits
  • Academy courses
    • ~50% discounted
    • Mentions a PrusaSlicer course discount and access/upgrade path:
      • Access to a future Slicer 3.0 course once fully released
  • Also references smaller discounts (paint sets/merch)
• Education highlight:
  • Prusa Academy courses are described as well-reviewed and worth it, including a Blender course emphasizing shortcut keys and efficiency

6) Accuracy explanation: in-house production feedback loop

• When asked why Prusa accuracy is high, the stream claims:
  • Prusa uses its own machines in the farm to produce parts for printers
• Resulting “feedback loop” improves:
  • Slicer software
  • Profiles
  • Machine behavior
• Overall idea:
  • Slicer + profiles + hardware are continuously harmonized to improve accuracy

7) Filament roadmap: CMYK sets + additional colors + lightweight PLA + limited editions

• Next releases mentioned:
  • CMYK filaments (bundles next week)
    • Available individually and in bundles
    • Priced the same as regular PLA
    • Two extra colors planned alongside the mixing set:
      • Gold and silver (color-mix oriented)
    • Materials described as translucent/blended to work well with the color-mix style
  • Lightweight PLA release (niche; expected shortly)
  • A limited edition filament teased (details withheld) with an “extra special” expected look
• Limited edition reruns:
  • Reruns depend on feedback/interest (e.g., how fast bundles sell out)
  • They ask where the community should express interest; mentioned platforms include:
    • Reddit, Twitter/X, forums, Discord, Facebook (noted as less monitored)

8) Community hardware/software ideas: home labs, sensors, monitoring dashboards

• Home-lab automation interests discussed:
  • Home Assistant on a Raspberry Pi (with plans for bigger setups later)
  • Example automation: motor-driven blinds controlled via Home Assistant with time-based open/close/tilt
• Storage best practice mentioned:
  • Put Home Assistant on SSD not SD card (to avoid wear/read issues)
• Additional self-hosting ideas:
  • A Discord honeybot/honeypot (“Mad Honey”) running on a home lab server
  • Discussion includes maker/open-source brainstorming (e.g., farmbots, remote-control tractors/plows)

9) Slicer 3 Lua plugins: “Bad Apple” flipbook demo + backend architecture flexibility

• A creator/demo shows a Lua plugin that can generate Bad Apple inside PrusaSlicer:
  • Export frames to SVG
  • Convert SVGs to layers
  • Produce slices for every layer of the animation
• Framed as:
  • A stress test / proof of what plugins can do
• Why it’s possible:
  • Slicer 3’s backend architecture changed, making it easier to extend and experiment with (referred to as easier “jank-testing” than other slicers)
• Teased next plugin idea:
  • A Tetris plugin attempt (joke/proof-of-concept)

10) Hardware reliability/updates: Excel upgrades, XL enclosure + ventilation

• They discuss:
  • Excel heater / chamber heater
    • Interest in eventually standardizing a safe chamber heater option
    • Mention of improved reliability and possible standardized heater part for the Core One / C1L ecosystem
    • Concern about overheating (referenced an earlier beta “easy bake oven” failure story)
  • XL enclosure “plus upgrade”
    • More “proper sealing” and installation changes
    • Acknowledges earlier fully sealed approach caused issues—ventilation matters
    • Product page details said to be lacking; expecting more pictures/clarity

11) Live events/travel schedule + announcements

• Events mentioned around September:
  • Maker fairs (Orange County, Bay Area)
  • 3D Printopia (Philadelphia; venue details and local highlights discussed)
  • IMTS (Chicago; large manufacturing conference)
    • They’ll share a booth with Oak Ridge National Laboratories
• A back-to-school sale explicitly called out as live during the stream
• Printopia guidance:
  • Entry fee mentioned; free passes offered via DM
