This chckx petg 3d printer review focuses on the CHCKX Grey 1.75mm PETG Filament. It is a 1kg spool of grey filament designed for reliable layer adhesion and durability. The two specs that define this product are its 1.75mm diameter and a dimensional accuracy of +/-0.02mm. This tolerance ensures consistent extrusion, which helps prevent clogs and uneven prints. The material combines the ease of use found in PLA with the toughness of ABS. You get a spool that resists moisture absorption and warping. This makes it a practical choice for functional parts that need to withstand impact without cracking during or after the print.
What stands out
- Dimensional accuracy of +/-0.02mm for consistent extrusion
- 1.75mm filament diameter suitable for most printers
- High impact resistance and toughness for durable parts
- Low moisture absorption reduces risk of print cracks
Who it fits
Good fit for
You should choose this filament if you print functional prototypes or mechanical parts that require strength. The +/-0.02mm tolerance helps you achieve precise dimensions without frequent calibration. It suits users who want the durability of ABS but struggle with warping. The grey color is ideal for industrial-looking components. If you need a material that flows smoothly and resists clogs, this PETG option provides a stable print experience. It is a solid choice for makers who prioritize reliability and mechanical performance in their daily prints.
Who should skip it
You might want to look elsewhere if you need a wide variety of aesthetic finishes. This listing offers a standard grey color and does not mention metallic, translucent, or matte specialty options in this specific variation. If you require a specific color palette for artistic projects, this single-color spool may not suffice. Additionally, if you are using a printer that strictly requires a different filament diameter, such as 2.85mm, this 1.75mm spool will not fit your hardware. The focus here is on mechanical utility rather than decorative variety.
Verdict: This CHCKX PETG spool offers reliable dimensional accuracy and impact resistance for functional printing. It is a practical choice for users needing durable parts with consistent extrusion.
CHCKX PETG Key Specs Explained
Filament Diameter: 1.75mm
This is the standard width for most desktop 3D printers. You need this exact size to fit into your printer’s extruder gear. If the diameter varies, your printer may under-extrude or clog. This size ensures consistent feeding through the hotend, which is critical for maintaining uniform layer height and overall print quality without manual adjustments.
Dimensional Accuracy: +/-0.02mm
This tolerance level indicates high precision in the filament's thickness. A variance of only two hundredths of a millimeter helps your printer maintain consistent flow rates. This reduces issues like stringing, under-extrusion, or clogs. You get smoother prints with better detail. This accuracy is essential for functional parts that require tight fits and reliable mechanical performance.
Material Type: PETG
PETG offers a balance between the ease of PLA and the durability of ABS. It provides strong impact resistance and good chemical stability. You benefit from fewer warping issues compared to ABS while maintaining toughness. This material is ideal for functional prototypes, outdoor items, or mechanical parts that need to withstand stress without cracking or breaking under pressure.
Net Weight: 1kg
This weight represents the amount of filament on the spool. It determines how many prints you can complete before needing a refill. One kilogram is a standard unit for hobbyists and professionals. It allows you to calculate material usage for larger projects. This size is manageable for storage and fits most standard spool holders on 3D printer beds.
Design and Build Details
The CHCKX Grey 1.75mm PETG Filament is a single-material spool designed for consistent extrusion. According to the listing, the material is pure PETG. This choice gives you a filament that balances the ease of use found in PLA with the durability typically associated with ABS. You get good impact resistance and high toughness without the common issue of edge warping. The listing notes that the surface has good gloss and layer lines are seamless. This means your prints will look smooth with minimal post-processing. The material is also described as hard to crack and not easy to absorb moisture, which helps maintain stability during long prints.
The physical build focuses on precision and weight. The filament diameter is 1.75mm with a dimensional accuracy of +/-0.02mm. This tight tolerance ensures the filament feeds smoothly into your extruder gear. You should experience no clogs or bubbles during printing. The spool holds 1kg of material, which is approximately 2.2lbs. This standard weight allows for moderate-sized projects without frequent spool changes. The listing also mentions high translucency for this grey variant. You can expect fluid discharge and high-precision results. The recommended print temperature ranges from 240 to 260°C, with a build plate temperature of 70 to 80°C. These settings support the material’s stability and help you achieve strong layer adhesion for functional parts.
Setup And Daily Use
Setting up this filament is straightforward. The listing recommends a printing temperature between 240°C and 260°C. You should set your build plate to 70°C to 80°C. These ranges are typical for PETG. They help ensure proper layer adhesion without excessive warping. The filament has a dimensional accuracy of +/-0.02mm. This tight tolerance means the strand stays consistent. Your printer feeds it smoothly. You avoid clogs and uneven extrusion. The material is designed for high translucency and smooth discharge. It does not produce bubbles or clogs during printing. This stability reduces the chance of cracks. The surface finish has good gloss. Layer lines are seamless and invisible. This results in a clean look without post-processing. PETG combines the toughness of ABS with the ease of PLA. It has strong impact resistance. You get high durability without the warping issues common in other materials. The filament is not easy to absorb moisture. This helps maintain stability over time. You can store it in a dry place. The spool holds 1kg of material. It weighs 2.65 pounds. This size fits standard 3D printers. You get reliable performance for everyday projects. The grey color provides a neutral base. It works well for functional parts. The product is available in other colors and sizes. You can choose from options like white fiberglass or transparent purple. The brand offers customer support. You can contact them if you have questions. The focus is on consistent printing. You get a stable filament that handles well. The smooth discharge ensures no interruptions. This makes it suitable for long prints. The material’s properties help you achieve professional results. You do not need to adjust settings frequently. The recommended temperatures work as intended. The dimensional accuracy supports precision. You get reliable layers every time.
Before You Buy This Filament
You should verify your printer’s extruder type before loading this spool. Most desktop models handle 1.75mm filament well, but bowden setups may require slightly higher temperatures. Ensure your build plate is clean and properly leveled. PETG adheres strongly, so using a glue stick or painter’s tape helps with removal. Store the spool in a dry place. The listing notes it absorbs moisture, which can cause bubbles or poor layer bonding. Keep it sealed in its original vacuum packaging when not in use. This grey variant offers good translucency, making it suitable for functional parts that need some light transmission. It sits alongside other options in 3D Printers & Making Tools as a durable, mid-range choice. If you need high impact resistance, this spec-based PETG delivers. Check your nozzle size as well. Larger nozzles may print faster but reduce detail. This filament works best with standard 0.4mm nozzles for balanced results.
Check before you buy
- Confirm your printer accepts 1.75mm filament diameter.
- Check if your extruder is direct drive or bowden.
- Ensure your build plate is clean and leveled.
- Verify your nozzle size matches your detail needs.
