3D-Fuel Pro PCTG is like PETG but better in many ways. It is tougher (up to 20x tougher than PETG), more chemically resistant, and has even greater clarity than PETG. Pro PCTG is an easy-to-use material with a lower moisture absorption rate than PETG and doesn't require an enclosure - use it just like PETG. The broad color selection and ease of printing make it an ideal choice for printing in a multi-color 3D printing system like the Bambu Lab AMS. Print Profiles Print profiles for Pro PCTG on the Bambu Lab printers are available here. Bambu AMS Compatibility Since October 2023, the 3D-Fuel Standard PLA+ has been manufactured using an AMS-compliant spool (more info on our spool sizes and weights). Since it takes time for some colors to move through our warehouse inventory, you may receive an older spool type. This is still compatible with the AMS, but you must leave the lid open a few mm. Pro PCTG is 20-50% More Impact Resistant Than PETG Key Reasons for Better Impact Toughness: Molecular Structure: PCTG contains cyclohexane dimethanol (CHDM), which gives it increased flexibility and toughness compared to PETG’s ethylene glycol structure. Flexibility vs. Brittleness: PCTG is more ductile, allowing it to absorb and dissipate energy during impact without cracking or shattering. Layer Adhesion: PCTG has better inter-layer bonding when 3D printed, reducing weak points in the structure where impact forces might cause failure. Real-World Implications: Drop Resistance: PCTG parts are less likely to crack, chip, or break when dropped, making it ideal for high-impact applications like enclosures or wearable devices. Repeated Stress: PCTG can endure repeated bending or sudden forces better than PETG, making it more suitable for hinges, clips, and flexible parts. Durability in Extreme Conditions: PCTG resists embrittlement under low temperatures, maintaining its toughness in environments where PETG may fail. Example Use Cases Benefiting from PCTG's Toughness: Protective housings for electronics or tools. Drone parts and propeller guards. Flexible clips, snap-fits, and living hinges. Impact-resistant containers or enclosures. Chemical Resistance Chemical Type Examples PCTG Advantage PETG Limitation Comparison (CRR) Alcohols Isopropyl alcohol (IPA), ethanol, methanol Resists prolonged exposure without degrading or cracking. Degrades or stress cracks with high alcohol concentrations over time. 1.8 Hydrocarbons Hexane, heptane, gasoline, mineral spirits Better resistance to hydrocarbon-based solvents. Softens or weakens when exposed to hydrocarbons. 2.0 Acids Acetic acid, citric acid, phosphoric acid Maintains structural integrity in mild to moderately concentrated acids. Degrades faster in acidic environments at higher concentrations. 1.4 Bases (Alkalis) Sodium hydroxide, potassium hydroxide, ammonium hydroxide Better resistance to strong alkalis. May crack or degrade when exposed to strong bases. 1.33 Cleaning Agents Bleach (sodium hypochlorite), industrial degreasers, detergent solutions Withstands harsh cleaning agents without discoloration or damage. Discolors, cracks, or loses properties with harsh cleaning agents over time. 1.5 Oils and Lubricants Engine oils, hydraulic fluids, cutting oils Resists degradation from prolonged exposure to oils. Absorbs oils over time, potentially leading to swelling or weakening. 1.6 Ketones Acetone, methyl ethyl ketone (MEK) Performs slightly better in low-concentration ketones. Softens or dissolves more readily in ketone-rich environments. 1.2 Pro PCTG Has Lower Moisture Absorption Than PETG PETG: Hygroscopic: PETG absorbs moisture from the air, but at a relatively low rate compared to more hygroscopic materials like nylon or TPU. Moisture Absorption Rate: Approximately 0.2–0.3% by weight after prolonged exposure to humid environments. Effects of Moisture: During printing, moisture in PETG can lead to stringing, bubbling, and surface defects due to water vaporizing in the hotend. Mechanical properties (like impact strength) can slightly degrade over time with prolonged exposure to high humidity. PCTG: Slightly Lower Moisture Absorption: PCTG absorbs less moisture than PETG, typically around 0.1–0.2% by weight. Improved Resistance: Due to its cyclohexane dimethanol (CHDM) component, PCTG’s molecular structure makes it less hygroscopic and more resistant to moisture-induced degradation. Effects of Moisture: PCTG generally performs better than PETG in humid conditions, retaining clarity, toughness, and dimensional stability for longer periods. Why the Difference? Molecular Structure: PETG’s glycol modification increases flexibility but leaves the material slightly more hygroscopic. PCTG’s modified structure with CHDM reduces the polar sites available for moisture interaction, resulting in less absorption. Practical Implications: 3D Printing: PETG: Requires drying mo..
