* '''Enclosed CoreXY Printers''' — Fast, versatile machines good for most work. Enclosure allows ABS/ASA in addition to PLA and PETG.
** '''[[Bambu_Lab_X1C|Bambu Lab X1 Carbon]]''' — Fully enclosed, AMS multi-color/multi-material, lidar first-layer inspection. Our most automated printer; great for reliable multi-color prints. 📄 [[Bambu_Lab_X1C|Full Machine Wiki Guide →]]
** '''[[Elegoo_Centauri_Carbon|Elegoo Centauri Carbon]]''' (×3) — Enclosed CoreXY workhorses; our primary everyday machines. Fast, easy to use, filtered enclosure. 📄 [[Elegoo_Centauri_Carbon|Full Machine Wiki Guide →]]


== 📋 Before You Print — Member Checklist ==
* '''[[CreatBot_F430|CreatBot F430]]''' — Large-format, fully enclosed, heated chamber (70°C) with dual extruders reaching 420°C. For engineering materials (Nylon, PC, CF) and large industrial parts. ⚠️ Advanced machine — training required. 📄 [[CreatBot_F430|Full Machine Wiki Guide →]]


'''A few quick steps every time you start a print — please don't skip these:'''
* '''[[Anycubic_Kobra_Max|Anycubic Kobra Max]]''' — Large-format open-frame Bowden printer (400×400×450mm). GRM's go-to for oversized single PLA prints. Open frame — PLA/PETG only. 📄 [[Anycubic_Kobra_Max|Full Machine Wiki Guide →]]


# '''🏷️ Label your print with a sticky note.''' Write your '''name''' (and a '''phone number and/or email''' if you can) on a sticky note and attach it to the printer you're using. If a print fails or there's an issue, we need to know whose job it is and how to reach you.
* '''[[Prusa_MK2|Prusa MK2]]''' — Reliable open-frame Cartesian printer; good for straightforward PLA/PETG prints. A dependable classic.
# '''⚖️ Write down the filament weight.''' Note the '''weight the slicer estimated''' (in grams) on your sticky note. This is how we track material use for paying for filament — jot it down before you walk away.
# '''👀 Don't hit print and leave.''' '''Stay for the first few layers''' and make sure they're going down cleanly with good bed adhesion. The first layer is where most prints fail — catching a bad start here saves your whole print (and everyone's filament and time).

== Safety & Usage ==


=== General Safety Rules ===
=== General Safety Rules ===
* Complete training before using any printer
* Complete mandatory training before using any printer
* Sign in/out on equipment log
* Sign in on the equipment log
* Never leave prints unattended for extended periods (especially first layer)
* '''Never leave the first layer unattended''' — it's the most common failure point
* Check in on long prints periodically
* Report jams, failures, and maintenance issues
* Report jams, failures, and maintenance issues
* Clean up after your print job
* Clean the bed and remove scraps when you're done
 
=== Operating Procedures ===
# Complete mandatory training before use
# Sign in on the log sheet
# Load your model in the machine's recommended slicer, using the matching profile
# Verify the correct filament is loaded and the correct plate/surface is installed
# Confirm the bed is clean and (where applicable) adhesion aid is applied
# Start the print and watch the first layer
# Stay reachable during the print; check in periodically on long jobs
# Allow parts to cool before removing from the bed
# Clean the bed and remove supports/scraps
# Sign out on the log sheet


=== FDM Printer Safety ===
=== FDM Printer Safety ===
* '''Hot surfaces''' - Nozzle reaches 250°C+, bed reaches 100°C+
* '''Hot surfaces''' — nozzles reach 250°C+ (up to 420°C on the F430) and beds reach 110°C+
* Do not touch nozzle or heated bed during or immediately after printing
* Do not touch the nozzle or heated bed during or immediately after printing
* Allow parts to cool before removing from bed
* Do not touch the nozzle or bed during auto-leveling
* Use scraper carefully to avoid injury

* Keep flammable materials away from printer
* Use scrapers and cutters carefully — cut and scrape away from your body
* Ensure adequate ventilation, especially for ABS/ASA
* Keep flammable materials away from printers
 
* Do not reach into a machine while it is running — moving parts can pinch or injure
=== Resin Printer Safety ===
* Ensure adequate ventilation, especially for ABS/ASA (use enclosed machines only)
* '''Nitrile gloves are MANDATORY when handling resin'''
* '''Safety glasses required when working with resin'''
* Uncured resin is toxic and a skin sensitizer
* Work in well-ventilated area or use enclosure with extraction
* Do not pour resin down drain - cure and dispose properly
* UV light can damage eyes - never look directly at UV source
* Wash skin contact immediately with soap and water
* Keep resin away from heat and direct sunlight

=== Material Storage ===

* Label spools clearly with material type
* Return shared filament and tools to their storage location when done


=== Waste Disposal ===
=== Waste Disposal ===
* Failed PLA prints - can go in trash
* Failed PLA prints and supports — regular trash
* Failed ABS/other prints - check local recycling
* Failed ABS/PETG/other prints — check local recycling options

Software & Design

🏆 Use the Slicer That Matches Your Machine

A slicer converts your 3D model (STL, OBJ, 3MF) into the G-code the printer follows. Each machine at GRM has a recommended slicer with pre-tuned profiles — always start with the profile that matches your machine. All of these slicers are free.

FDM Printer Safety

  • Hot surfaces — nozzles reach 250°C+ (up to 420°C on the F430) and beds reach 110°C+
  • Do not touch the nozzle or heated bed during or immediately after printing
  • Do not touch the nozzle or bed during auto-leveling
  • Allow parts to cool before removing from the bed
  • Use scrapers and cutters carefully — cut and scrape away from your body
  • Keep flammable materials away from printers
  • Do not reach into a machine while it is running — moving parts can pinch or injure
  • Ensure adequate ventilation, especially for ABS/ASA (use enclosed machines only)

Fume Safety

Material Fume Risk Ventilation / Machine Requirement
PLA Low Recommended; any machine
PETG Low–Medium Recommended; any machine
TPU / Flexible Low–Medium Use a direct-drive machine (X1C, Centauri, F430); not the Bowden Kobra Max
ABS / ASA High — styrene fumes Enclosed + filtered machine only (X1C, Centauri, F430); never on open-frame machines
Nylon Medium — may emit irritants Enclosed machine; keep dry
PC (Polycarbonate) High Enclosed, heated-chamber machine only (F430) — requires approval

Approved Materials by Machine

Material X1 Carbon Centauri Carbon CreatBot F430 Kobra Max Prusa MK2
PLA ✅ ✅ ✅ ✅ ✅
PETG ✅ ✅ ✅ ✅ (with care) ✅
TPU / Flexible ✅ ✅ ✅ ❌ (Bowden — jams) ❌ (not recommended)
ABS / ASA ✅ (enclosed) ✅ (enclosed) ✅ (enclosed) ❌ (open frame) ❌ (open frame)
Nylon Caution — keep dry Caution — keep dry ✅ (heated chamber) ❌ ❌
PC (Polycarbonate) ❌ (no chamber heat) ❌ (no chamber heat) ✅ (with approval) ❌ ❌
Carbon-Fiber filled ✅ (hardened nozzle) ✅ (hardened nozzle) ✅ (hardened nozzle) ❌ ❌ (nozzle not hardened)

When in doubt about a material/machine combination, ask a volunteer before printing. Open-frame machines (Kobra Max, Prusa MK2) cannot hold the ambient temperatures ABS/ASA need and should not run them.

Prohibited / Restricted Practices

Practice Reason
Running ABS/ASA on open-frame machines Warping/cracking and unfiltered styrene fumes — enclosed machines only
Running TPU/flexible through the Kobra Max Bowden tube causes flexibles to buckle and jam — use a direct-drive machine
Abrasive (CF/GF) filament in a non-hardened nozzle Wears out brass nozzles quickly — hardened-nozzle machines only
Leaving the first layer unattended Most failures happen in the first layer — stay present
Printing unknown/unlabeled filament Unknown melt temps and fumes — verify material before printing

Material Storage

  • Keep filament dry — store hygroscopic materials (Nylon, TPU, PETG) in sealed containers with desiccant or in the dry box
  • Label spools clearly with material type
  • Return shared filament and tools to their storage location when done

Waste Disposal

  • Failed PLA prints and supports — regular trash
  • Failed ABS/PETG/other prints — check local recycling options
  • Keep scraps off the floor and out of machine rails

Emergency Procedures

  • Fire extinguisher location: [TO BE FILLED IN]
  • First aid kit: Near the bathroom inside the main makerspace room
  • Emergency contact: Chris Kaminsky — 616-802-7088 — chris@grandrivermakerspace.org
  • In case of uncontrolled fire: Evacuate immediately and call 911
