| |
| 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.

| == Safety & Usage ==
| |
| | |
| === General Safety Rules ===
| |
| * Complete mandatory training before using any printer
| |
| * Sign in on the equipment log
| |
| * '''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
| |
| * 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 ===
| |
| * '''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 ===
| |
| {| class="wikitable" style="width:100%;"
| |
| |-
| |
| ! 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 ===
| |
| {| class="wikitable" style="width:100%;"
| |
| |-
| |
| ! 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 ===
| |
| {| class="wikitable" style="width:100%;"
| |
| |-
| |
| ! Practice !! Reason
| |
| |-
| |
| | style="background:#ffe4e4;" | '''Running ABS/ASA on open-frame machines''' || style="background:#ffe4e4;" | '''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 — [tel:6168027088 616-802-7088] — [mailto:chris@grandrivermakerspace.org chris@grandrivermakerspace.org]
| |
| * '''In case of uncontrolled fire:''' Evacuate immediately and call 911
