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.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.

AMAZING debut novel!!!
Format: Kindle
Plot ⭐️⭐️⭐️⭐️ Spice 🌶️🌶️.5 Romance 💘💘💘 Vibes ⭐️⭐️⭐️⭐️⭐️ Dual 1st person POV - Ara (26) & Rogue (39 - but looks mid-20s: they can live hundreds of years so this isn't that large of a gap as it could've been which I heavily appreciate lol) Tropes: enemies to lovers, fae/human wars (deep hatred for each other), shifters (dragons- MMC can only partial shift with wings), one horse, one bed, touch her and d!e, found family, abduction turned to freedom The Last Storm is the debut novel from JD Linton and let me tell you, you guys NEED to read this. The plot was engaging and the editing was was amazing (especially for a debut novel). Our FMC, Ara, is stuck in her gilded cage longing for a life outside of her small town. She uses her books to escape and live vicariously through the pages (honestly, relatable). After her father announces her betrothal to her childhood friend (to whom she has no romantic feelings for), Ara tumbles unknowingly into a desperate plot trying to stop the humans from slaughtering the Fae. As one can expect from an enemies to lovers / kidnapper/captive romance, Ara fights her attraction and lust towards our MMC, Rogue (the King of the Fae), for as long as she can. Upon seeing Ara for the first time, Rogue is instantly aware that she is his fated mate (not a spoiler). Since she is the General's only daughter, he plans to abduct her and use her as leverage to stop the brutality. During Ara's time in Rogue's captivity, their banter and chemistry continue to rise until they finally boil over and come together (quite literally, and many times I may add 😉). Here's what I LOVED: - Rogue continuously seeks advice from his elders and deeply respects their opinions and life experience and tries to implement their recommendations - Rogue makes many mistakes in the beginning but we see him actively work on not repeating them as the book progresses. The level of self-awareness and his ability to change his behavior was impressive - The magic system is intricate and we have only scraped the surface. As the series continues and Ara progresses in her powers, I'm sure we'll get to see more of this. I absolutely LOVE the messaging system that is used in this book. - Ara's struggles are so human and so raw. She is experiencing so much guilt and pain and hurt and getting to see her work through each of these emotions is inspiring. Especially as her and Rogue get closer and she learns she can lean on him as well, that she is not alone. - While this is the start of a series, there is NO cliffhanger! There's a bit of a teaser of something major that is going to happen at the start of the next book, but it's not a cliffhanger in the sense that we aren't sure if someone is going to live or d!e or if they'll be separated. For that, I am very thankful! This book was so much fun that I will definitely be returning to book 2, even if it takes several months (or longer since this is an debut author) to publish! - Lastly, the cover is GORGEOUS! And I love the title! I'll copy a few of my favorite quotes below so you can have a little taste of the author's writing and the world she's cultivated. 😊 Top Highlights from The Last Storm On days like this, when my heart was heavy and my mind clouded, I resorted to books— to escape, to forget, to find freedom where I had none. If I were to marry him, my face would always be turned to the window, searching for more, and if not that, I would be a shell of the person I am now. I stepped back to admire her, thr0bbing at the sight. She was the most beautiful woman I had ever seen. To ever exist. Nothing, no one, had ever deserved to be worshiped more. All men should be made to kneel before her. But she would have to settle for me. The taste of her met my t0ngue as my scent merged with hers, forever branding her. Mine. I l!cked the wound. Hers. Completely and utterly hers. I didn’t claim her in ownership. I claimed her as my one. Devoted myself to one. With that mark, my body and soul were bound to her. I would never be with anyone else, emotionally or physically. It would be her or no one, until my last breath. “Scream my name. Let everyone know who I belong to.” I had never really cared about the weather before, but now, clear skies meant everything to me, and I was grateful to see another calm morning. “There will never be another woman for me.” He paused. “Ever.” I stilled at his words. “What… Why?” “This”— his thumb slid down across the mark—“ is a symbol of… surrender. I know you believe that it was my claim upon you, but it wasn’t. It never was. I bound my body and soul to you, little storm.” “I also know that it is more than this tiny, insignificant mark on your skin that binds me to you. It’s you. All of you. Your strength and resilience. Your determination to endure no matter what fate throws at you. Your love for love and stories and hope. You are entirely the opposite of everything that I am and I would gladly wear your shackles if it meant I could have you.” My mate. Mine. And then everything shifted and I understood. I understood everything. The surrender. The deep, soul-craving longing. Bound. I was bound to him. Body and soul. Entirely his. “I would’ve waited forever,” he whispered back, understanding. Seriously, everyone.. add this to your TBR!!

A Decent Fae Romance
Format: Kindle
** 3.5 Stars rounded up to 4 ** First off I want to say that I found the author, J. D. Linton, on TikTok right before the release of the sequel. I bought the first 2 books to support her release, so congrats to her for the release of the sequel! Overall, I liked the story & plot, I liked the characters, and I liked the spice. The downfalls: not enough development between the characters for the romance, and it leaned a little heavy into the tropes. A lot of stuff is told to you, which could have been used as devices to drive the plot and emotions of the characters. 🛑🛑 Mild Spoilers ahead, I tried to hide the obvious ones 🛑🛑 This is very obviously a fated mates, which is a trope I usually really enjoy. But I wish the relationship between Ara & Rogue had much more development before it's realized that they're mates, instead of Rogue knowing almost immediately and using it for nefarious purposes (at least in the beginning before they get to know each other). By revealing this within the first quarter of the book, I feel like it leaves less room for them to fall for each other organically (albeit with help from the mating bond) and they love each other because of the mating bond. I was disappointed as soon as Rogue know (literally only 5% in) and I literally made a note: "As much as II love a good mating trope, I wish we had to work for it a little more. Where's the fun in just telling us?" I believe that by holding out and feeding the reader snippets of a potential bond, it would've been more rewarding as a reader. I also wish there was more world building - we are told of a war between human & fae but don't get to really experience any of it. Ara is sheltered in her human home, then sheltered in Rogue's castle. There's bits and pieces about what the war has done on either side - but we're more told of the aftermath and don't really experience any of it. Ara's father is supposed to be the king's #1 general - yet he is at home with his family & with Ara for the first couple chapters. Her, her family, nor her village seem to be affected by the 10 year war going on on their borders. I wish there was a little more setup to make this conflict - an actual war - feel more than a skirmish between fighting territories. Linton could also be a little repetitive - with the biggest culprit being when Ara is upset she "brings [her] knees to [her] chest]" and either sits like that or cries. Every time she is upset this phrase is mentioned. I would get it if this was her crutch, or how she copes with grief and stress, but that should be explained why she does it so often or it becomes repetitive. I started to get annoyed with how often she would sit like this solely because it happens every couple chapters. However, I did really like the spice. I love an enemies to lovers trope, especially when it results in spicy scenes. The spicy scenes weren't anything new, but they were fun. Wish there were more but that could also just be me - there is no such thing as too much spice 😂 Would I read again? Probably not, I'm super picky with rereads. Although I did genuinely enjoy my first read through! Will I continue the series? Probably, at least for the sequel. As for #3, kind of depends on where I am with my TBR once that is released All in all an enjoyable, fast paced read
