Description
QIDI Cool Plate: Spring Steel Build Plate for PLA & PETG
The QIDI Cool Plate is a 0.5mm spring steel build plate with a dual-sided low-temperature super-sticky coating, designed exclusively for PLA and PETG printing on QIDI Plus 4 (305x305mm) and Q1 Pro (245x245mm), delivering zero-glue first-layer adhesion at bed temperatures as low as 30-70°C for $99.99.
The QIDI Cool Plate solves the #1 problem in 3D printing — first-layer adhesion failure — without glue, hairspray, or messy adhesives. Its proprietary super-sticky coating holds PLA and PETG firmly during printing and releases cleanly when cooled, while the flexible spring steel base allows you to bend the plate and pop prints off without scraping. Designed for low-temperature printing (max 120°C), it saves energy and produces smooth, matte bottom surfaces on every print.

How the QIDI Cool Plate Works
The QIDI Cool Plate uses a three-layer architecture to achieve reliable adhesion and easy removal:
- Spring steel core (0.5mm) — Provides rigidity during printing and flexibility for removal. The plate sits on the printer's magnetic base and stays flat at printing temperatures.
- Super-sticky coating (0.05mm per side) — A proprietary low-temperature adhesive coating that grips PLA and PETG at 30-70°C. The coating is applied to both sides, doubling the usable life.
- Natural texture surface — Micro-textured finish creates mechanical grip for small contact areas and produces a smooth matte bottom surface on finished prints.
When the bed is heated to 45°C (PLA) or 70°C (PETG), the coating becomes tacky and holds the first layer firmly. As the plate cools to room temperature, the coating loses tackiness, and the print releases naturally — often popping off on its own or with a gentle flex of the spring steel plate.
Temperature Settings by Filament

|---|---|---|---|---|
| PLA (standard) | 30-50°C | 45°C | Off for 1-2 layers | Excellent |
| PLA+ / PLA Pro | 40-55°C | 50°C | Off for 1-2 layers | Excellent |
| PETG (standard) | 50-70°C | 70°C | Off for 1-2 layers | Excellent |
| PETG+ / PETG Pro | 60-75°C | 70°C | Off for 1-2 layers | Very Good |
| Silk PLA | Not recommended | — | — | Too strong (may damage print) |
| ABS / ASA | Not compatible | — | — | Requires higher temp (120°C+) |
| Nylon / TPU | Not compatible | — | — | Coating not designed for these |
Pros & Cons
Pros (Advantages)
- Zero adhesive required — No glue, hairspray, or 3D LAC needed. The coating provides all adhesion.
- Low-temperature operation — PLA at 45°C, PETG at 70°C. Saves energy and reduces warping risk.
- Dual-sided coating — Both sides have the super-sticky coating, effectively doubling the plate's lifespan.
- Flexible spring steel — Bend the plate to release prints; no scraping required for most parts.
- Strong adhesion for small parts — Even prints with tiny contact areas stick firmly and do not scatter when removing the plate.
- Easy cleaning — Wash with water and mild detergent; no special cleaners needed.
- Smooth matte bottom finish — Natural texture produces a clean, professional-looking bottom surface.
- Energy efficient — Low bed temperatures (45-70°C) vs PEI (60-110°C) reduce power consumption by 30-50%.
- Large build area — 305x305mm for Plus 4, 245x245mm for Q1 Pro.
- Durable coating — Designed for long-lasting performance; scratches and dents from normal use are expected and do not affect adhesion.
- Quick installation — Simply place on the magnetic bed; no tools, no calibration.
- Consistent results — Coating provides uniform adhesion across the entire build surface.
Cons (Disadvantages)
- PLA/PETG only — Cannot be used with ABS, ASA, nylon, TPU, or engineering filaments that require higher bed temperatures.
- Max temperature 120°C — Cannot handle the 90-110°C+ bed temps needed for ABS/ASA/nylon.
- Silk PLA not recommended — Silk PLA adheres too strongly and may damage the print or coating upon removal.
- No acetone cleaning — Organic solvents (especially acetone) will damage the adhesive coating.
- Soft surface — The coating is relatively soft; sharp scrapers can scratch or gouge it if used aggressively.
- Magnetic base required — Only works on printers with a magnetic heated bed (QIDI Plus 4, Q1 Pro).
- Coating wears over time — The sticky coating gradually loses tackiness after hundreds of prints; both sides delay but do not eliminate this.
- Higher price than generic PEI — At $99.99, it is more expensive than generic PEI sheets ($20-40).
- Not for high-temp printing — Users who print ABS/nylon need a separate PEI or engineering plate.
- Edge thickness variation — The top edge may appear slightly thicker due to paint accumulation during manufacturing (normal but visible).
- Prints can stick too well — Some PETG prints may require waiting for full cool-down or gentle flexing to release.
- Limited printer compatibility — Only officially supported on QIDI Plus 4 and Q1 Pro; other printers may need size adaptation.
Installation Guide
- Power off and cool the printer. Ensure the heated bed is below 40°C before handling.
- Remove the old build plate. If using a PEI sheet or glass plate, remove it from the magnetic base.
- Clean the magnetic base. Wipe with isopropyl alcohol (90%+) to remove any dust, grease, or adhesive residue.
- Place the QIDI Cool Plate on the magnetic base. Align the plate with the edges of the heated bed. The magnetic base will hold it securely.
- Verify flatness. Run your hand across the surface to ensure there are no bubbles or lifted edges. The plate should lie completely flat.
- Re-calibrate Z offset. Because the Cool Plate has a different thickness (0.5mm steel + 0.05mm coating = ~0.6mm) than your previous plate, run a first-layer calibration test. Adjust the Z offset so the first layer is slightly squished.
- Set the correct bed temperature. PLA: 45°C, PETG: 70°C. Do not exceed 120°C.
- Start a test print. Print a 20mm calibration cube or first-layer test to verify adhesion and Z offset.
Important: Always re-calibrate your Z offset after switching build plates. Different plate thicknesses change the distance between the nozzle and bed, which can cause first-layer failures if not adjusted.
Print Removal & Maintenance
How to Remove Prints
- Wait for the build plate to cool to room temperature (25-30°C). The coating loses tackiness as it cools.
- Remove the plate from the magnetic base by lifting from the corner tab.
- Gently flex the spring steel plate — most prints will pop off on their own.
- For stubborn prints, use the scraper included with your printer to gently lift the edge. Pry carefully — the surface is soft.
- If a print is still stuck, wait 5-10 more minutes for complete cooling, or place the plate in a cool area for 2-3 minutes.
Cleaning & Maintenance
- Regular cleaning: Wipe with a dry or slightly damp cloth between prints. No frequent deep cleaning needed.
- Heavy dirt: Wash with warm water and mild detergent (dish soap). Rinse thoroughly and air-dry completely before reusing.
- Never use: Acetone, isopropyl alcohol (for deep cleaning), or any organic solvent — these will dissolve or damage the adhesive coating.
- Scraper care: Use a plastic or blunt metal scraper. Sharp blades can gouge the soft coating.
- Storage: Store flat in a dry area. Do not stack heavy objects on the plate.
- Coating life: Each side lasts approximately 200-500 prints depending on filament type and removal technique. Flip to the second side when the first side wears out.

Real-World Use Cases
- PLA prototyping — Low 45°C bed temp saves energy and reduces elephant foot on PLA parts.
- PETG functional parts — Strong adhesion at 70°C prevents warping and corner lift on PETG prints.
- Large flat prints — Super-sticky coating holds large footprints firmly, eliminating edge curl on PLA and PETG.
- Small delicate parts — Even tiny contact areas (5x5mm) stick securely; prints do not scatter when removing the plate.
- Batch printing — Multiple small parts on one plate all stick and release together when cooled.
- Beginners — No glue, no calibration headaches; just set temperature and print.
- Energy-conscious users — 45°C bed for PLA uses 30-50% less power than 60°C PEI beds.
Frequently Asked Questions
What is the QIDI Cool Plate and how does it work?
The QIDI Cool Plate is a spring steel build plate with a proprietary low-temperature super-sticky coating, designed exclusively for PLA and PETG. It works by using a tacky coating that grips filament at 30-70°C bed temperature, eliminating the need for glue or adhesives. When the plate cools, the coating loses tackiness and prints release easily. The flexible spring steel base allows you to bend the plate to pop prints off without scraping. It comes in 305x305mm for QIDI Plus 4 and 245x245mm for Q1 Pro, priced at $99.99.
What bed temperature should I use with the QIDI Cool Plate?
For PLA, set the bed to 30-50°C with 45°C recommended. For PETG, set 50-70°C with 70°C recommended. These low temperatures are possible because the super-sticky coating provides adhesion without relying on heat. The maximum surface temperature is 120°C — never exceed this, as it will damage the coating. The low-temperature operation saves 30-50% energy compared to PEI plates that require 60-110°C.
Can I use the QIDI Cool Plate with ABS, nylon, or TPU?
No. The QIDI Cool Plate is designed exclusively for PLA and PETG. ABS and ASA require bed temperatures of 90-110°C, which exceeds the plate's 120°C limit and will degrade the coating. Nylon requires high temperatures and often needs a PVA glue stick or PEI surface. TPU can be too soft and may stick too aggressively. For engineering filaments, use QIDI's PEI or engineering build plate instead.
How do I remove prints from the QIDI Cool Plate?
First, wait for the plate to cool to room temperature (25-30°C) — the coating loses tackiness as it cools. Remove the plate from the magnetic base and gently flex the spring steel; most prints will pop off. For stubborn prints, use the scraper included with your printer to gently lift an edge, then pry carefully. If still stuck, wait 5-10 more minutes or place the plate in a cool area. Never use a sharp blade, as the coating is soft and can be gouged.
How do I clean the QIDI Cool Plate?
For regular maintenance, wipe with a dry or slightly damp cloth. For heavy dirt or filament residue, wash with warm water and mild dish detergent, rinse thoroughly, and air-dry completely before reusing. Never use acetone, isopropyl alcohol, or any organic solvent — these will dissolve or damage the adhesive coating. Avoid abrasive scrubbers that can scratch the soft surface. The plate does not require frequent cleaning; the coating maintains adhesion for hundreds of prints between washes.
Is the QIDI Cool Plate better than a PEI sheet?
It depends on your filament choice. For PLA and PETG, the Cool Plate offers stronger adhesion at lower temperatures (45°C vs 60°C for PLA on PEI), no glue needed, and easier removal when cooled. PEI sheets are more versatile (work with ABS, nylon, TPU) and can handle higher temperatures (up to 130-140°C). If you only print PLA/PETG, the Cool Plate is better. If you print multiple filament types, PEI is more versatile. The Cool Plate is dual-sided, effectively doubling its lifespan vs single-sided PEI.
How long does the QIDI Cool Plate coating last?
Each side of the Cool Plate lasts approximately 200-500 prints, depending on filament type, removal technique, and cleaning frequency. PETG tends to wear the coating slightly faster than PLA due to higher bed temperatures. Since the plate is dual-sided (coating on both sides), total lifespan is roughly 400-1000 prints before the coating needs replacement. Signs of wear include reduced adhesion, visible scratches, or coating peeling. Normal scratches and dents from printing are expected and do not significantly affect performance.
Which printers is the QIDI Cool Plate compatible with?
The QIDI Cool Plate is officially compatible with the QIDI Plus 4 (305x305mm size) and QIDI Q1 Pro (245x245mm size). It requires a magnetic heated bed to hold the spring steel plate. It is not compatible with QIDI X-MAX 3, X-Plus 3, or Max 4 due to different bed dimensions. For non-QIDI printers, the plate may work if the bed size matches and has a magnetic base, but QIDI only provides support for Plus 4 and Q1 Pro.
Can I use silk PLA on the QIDI Cool Plate?
No, QIDI does not recommend using silk PLA on the Cool Plate. Silk PLA contains additives that make it adhere extremely strongly to the super-sticky coating — so strongly that removing the print may damage the print itself or tear the coating. If you must print silk PLA, use a PEI sheet or glass plate with a PVA glue stick instead. For standard PLA and PETG, the Cool Plate works perfectly.
What is the shipping time and return policy for the QIDI Cool Plate?
Free US shipping takes 15-25 business days. Express shipping options are available at checkout for faster delivery. QIDI offers a 30-day free return policy — if you are not satisfied, return the product within 30 days for a full refund (must be in new condition with original packaging). The Cool Plate also carries a 90-day manufacturer warranty against defects. If the coating peels or the plate arrives damaged, contact QIDI support with your order number for a replacement.
