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:

  1. Molecular Structure:
    • PCTG contains cyclohexane dimethanol (CHDM), which gives it increased flexibility and toughness compared to PETG’s ethylene glycol structure.
  2. Flexibility vs. Brittleness:
    • PCTG is more ductile, allowing it to absorb and dissipate energy during impact without cracking or shattering.
  3. 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:

  1. 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.
  2. Repeated Stress:
    • PCTG can endure repeated bending or sudden forces better than PETG, making it more suitable for hinges, clips, and flexible parts.
  3. 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

  1. 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.
  2. 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:

  1. 3D Printing:

    • PETG: Requires drying more frequently, especially if exposed to humid environments, as even slight moisture absorption can lead to print defects (bubbling, stringing, poor adhesion).
    • PCTG: Requires less frequent drying, making it easier to handle in environments with higher humidity. It is also more forgiving if printed without drying.
  2. Storage:

    • Both materials benefit from being stored in airtight containers with desiccant.
    • PCTG will be less prone to degradation if exposed to moisture for extended periods compared to PETG.
  3. Long-Term Use in Humid Environments:

    • PCTG is more stable and less likely to lose mechanical properties over time in high-humidity settings.

Drying

For both materials, drying before printing and proper storage is recommended for optimal performance, but PCTG is less maintenance-intensive in this regard.

When you need to dry Pro PCTG, use a temperature of 60-70C for 4-8 hours.

One of the best purchases I've made in a while.
Format: Hardcover
As a devoted fan of the show from almost the very beginning, I followed all the interviews, sneak peeks, and DVD commentaries aggressively, so I thought I knew a good bit about every aspect of the show, from its influences to its creation process to little trivia bits about the finished episodes. I told myself I didn't need the art book because it would tell me little about Avatar that I didn't already know. For a while I was able to hold off buying this book, but the art in Avatar is so beautiful that I finally broke down and got it, telling myself that I might as well dish out twenty bucks to have a nice hardcover Avatar book to add to my collection of flimsy cinemanga and Earth Kingdom Chronicles paperbacks. Now I'm writing this review to tell every fan out there who has had even a minute's hesitation in buying this book: DO IT. Avatar: The Art of the Animated Series covers everything you could dream of wanting to know about the show. I should have known Bryke would never do anything halfway. I was blown away by the obviously intense amount of effort the creators put into compiling such a thorough and well-put-together inside look at the creation process. They explain everything about Avatar's production, starting with their very first fateful meeting and taking fans all the way up through the end of the epic series. It's so neat to read about all their inspirations (especially if you're an anime fan; you'll probably recognize a lot of names) and some of the difficulties they had to overcome in order to make the show what it is today. It is a fantastic read from cover to cover. As you can tell when you use Amazon's "look inside" feature, the creator commentary is arranged in paragraph format with bold letters to tell which creator is speaking. They actually go into a lot more detail than I thought they would about almost everything. They spend a lot of time talking about the development of characters: their personalities, design characteristics, models, and any changes that were made and why. (Plus it's really neat to see the way some of your favorite characters looked like originally!) They mention the animals, settings, voice acting, martial arts influences, weapons and technology, and all sorts of other things, some that you may not even necessarily have thought about much before, like color schemes and drawing styles. I learned a lot of really neat things about the process behind Avatar's animation and about the Korean studio that did such a beautiful job animating the series. The thing I like most about this book is the great variety of art it showcases. There are original character concepts by various crew members, background sketches and paintings, real storyboard action sequences, martial arts references, detailed clothing and weapon designs, descriptions and illustrations of Avatar-verse animals, screenshots from the show and the original pilot episode, press and/or promotional art, and even some photos Mike and Bryan took on some of their trips to places that inspired the layout of the Avatar universe. And to top it all off, there is at least a one-page spread for each one of Avatar's 61 chapters that highlights some of the strongest points in each episode, whether it's new characters, locations, technology, action sequences, or a combination of several of these. Needless to say, this book is a must-have for all Avatar fans. Whether you're a casual fan who just happened to fall in love with the art (and there is plenty of it in this book, all amazing quality despite the fact that much of it is simply sketched) or you're a die-hard Avatard who wants to know everything about everything, trust me when I say that this compilation is worth every penny and more. As for the packaging and shipping, I have very little to say - the item was wrapped adequately and arrived when it said it would. No problems there. The only minor (and I do mean minor) problem that I had was that one of the corners was bent when it arrived. It probably would have happened anyway, though, through regular use, so it's not really something to complain about. Everything else was fine, and the price is excellent given the durable binding and beautiful thick pages (not to mention the content). I know I've said this so many times that it's probably starting to sound old, but if you want a good look behind the scenes of the greatest cartoon of our generation, this is it. Other creators, take note: this is how TV series art books should be.

Spellbinding
Format: Hardcover
This is a wonderful art book for a spellbinding animation series. Making the series took 6 years, hundreds of artists, and hundreds of thousands of drawings. This book showcases a selection of some really beautiful illustrations. There are loads of character and background designs inside, in sketches and in their finished coloured form. The main characters like Aang and others come with cool animation sequences created with pencils. Also included are many of the discarded concepts which were difficult to animate or doesn't suit the story. Appa had some really awesome spiral horns but were discarded, unfortunately. The character drawings are superb. Just by looking at their different expressions you can pretty much guess their characteristics. Besides the characters which includes the town folks and soldiers, there are also drawings for many miscellaneous stuff like storyboards, airships, hybrid animals, wanted posters, promotional posters, chibi (or super deformed) style and random doodles from meetings. Did I mention the background paintings? The world created is so beautiful! The whole book is annotated heavily by Bryan Konietzko and Michael Dante DiMartino. They talk about everything on production, from creating the pilot episode to Nickelodeon approving the final season. You can see and read about their influences and inspiration everywhere, from Buddhism, Studio Ghibli, Gainax, Chinese martial arts, etc. It's very interesting to see how they apply what they learned from research to their drawings and animation. This is a fantastic art book for the series and fans, which should appeal to anyone who hasn't watch the series. Good art appeals to all. Highly recommended! (There are more pictures of the book on my blog. Just visit my Amazon profile for the link.)
