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 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.
-
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.
-
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.

Great for Sensitive Skin
Color: Non-Tinted, Size: 1.7 Fl Oz (Pack of 1)
My face has always been sensitive to sunscreens, so I have to be careful with what I use on my face. (Others can cause burning sensations). This sunscreen is great. I had no issues, and unlike other sunscreens, sweat running didn't cause my eyes to burn or water which was great.
Keeps my skin protected against the hot Florida sun, so it works!

And the crowd goes mild
Color: Tinted, Size: 1.7 Fl Oz (Pack of 1)
I had heard such great things but I’m really left a little disappointed. I got the light tinted version, and it’s much darker than anticipated. And the smell is not great. It kind of smells like my grandpa’s trailer and not in a nice, nostalgic way. As a sunscreen though, I have no complaints. The protection is great and at the end of the day that’s what I really need out of this.

Gentle but effective
Size: 4 Fl Oz
I’ve used quite a few exfoliating products over the years, but I keep coming back to this one because blackheads seem determined to make themselves at home in my pores. No matter how consistent I am with the rest of my skincare routine, they always find a way to show up, especially around my nose and chin.
What I like most about this exfoliant is that it works without feeling harsh. It has a lightweight liquid texture that applies easily and absorbs quickly. Unlike physical scrubs that can leave my skin feeling irritated or over-exfoliated, this provides gentle chemical exfoliation with none of the rough scrubbing. My skin feels smoother after use, and I don’t get the tight, stripped feeling that some acne-focused products can cause.
After using it regularly, I notice fewer clogged pores and a visible reduction in blackheads. My pores also look less noticeable, and my skin texture appears more even overall. It helps keep congestion under control before it turns into larger blemishes, which is a big reason why it has remained a staple in my routine.
For me, this is one of those rare products that manages to be both effective and gentle at the same time. If blackheads and clogged pores are an ongoing battle, this has been one of the most reliable products I’ve found for keeping them under control while still being comfortable enough for regular use.
Summary: This exfoliant has earned a permanent spot in my skincare routine. It helps reduce blackheads, keeps my pores looking clearer, and improves overall skin texture without irritating my skin. For anyone dealing with persistent pore congestion, it’s easy to see why this product has such a loyal following.

If you actually understand how to use it, it's amazing.
Size: 4 Fl Oz
My skin type:
- Very Dry, easily dehydrated
- Oily nose
- Prone to stubborn acne and closed comedones
- Redness on chin and cheeks (not rosacea)
I already use a nightly Tretinoin cream (.04% concentration) to help with my acne and premature signs of aging but decided with my derm that incorporating a BHA would be a good idea to help with my seriously stubborn closed comedones and some irritating textural issues. It was between this and the Cerave SA lotion and I ultimately decided on this due to the higher concentration of salicylic acid.
It's moisturizing, and feels sticky for the first 5-10 minutes after application but seems to sinks in to something of a satin finish on me and I can no longer feel it on my skin. You just have to be a little patient. My skin feels well hydrated and plump after it settles and looks really smooth and my pores aren't as obvious. It sits just fine under makeup for me but I'm not a new user to chemical exfoliants so I don't have lots of dead skin pilling up or sloughing off when I use it, my skin is, for the most part, already very smooth outside the acne and CCs. Occasionally I'll apply it further down my neck/decolletage than usual and WOW do I old skin just ball up and peel right away - it's so gross but also satisfying. So those that don't exfoliate often or are new to BHA/AHAs will likely have issues with foundation until their skin adjusts (but it will adjust). My advice in those cases is to either use this at night for the first few weeks or just accept going barefaced for a little while if you can.
I'd strongly suggest not applying this product over anything that you feel does not dry down fully, the times I've attempted to use it after serums or heavier products it takes forever to sink in and sometimes never fully does. I save all my serums and essences for after this has absorbed and it's far easier to work with it as a result. My steps go like this most days: ACWell Licorice toner --- PC 2% BHA --- 10% Niacinamide serum --- TO Matryxil serum --- Secret Key Black Snail cream or Syn-ake cream w/ 3 drops Stratia Fortify oil --- Sunscreen.
It works fairly quickly IMO, on my neck where I typically don't apply my Tret at night I noticed the peeling and balling of dead skin on day one and on my face where I have a patch of really awful CCs I noticed them getting smaller and smoother by around day 3-4. I'm going on about 8 days now and they're barely visible unless I'm right up in the mirror and feel as if they're almost gone when I touch my fingers to that area. I do have some slight peeling of the skin around my mouth and nose but it's not terrible (likely because I already exfoliate the heck out of my skin with the tret).
Some tips and things keep in mind:
1)
DO NOT RINSE IT OFF. I don't understand some of the top reviews advising people to do that, it says on the bottle not to rinse and nearly all chemical exfoliators are meant to be left on until the next cleansing specifically so they can do their job. If you rinse it off you're either going to prevent it from properly exfoliating or end up irritating the hell out of your skin. If you have oily skin and feel this might be heavy on you than you can probably just use this on bare skin and then sunscreen if you use in the AM or a lightweight lotion/cream and be done with it, but you need to leave it on your skin.
2)
You have got to use sunscreen while you're using this product! Any BHA or AHA exfoliant causes increased sun sensitivity and you have to address that in your routine. You should already use sunscreen daily but it becomes a must when you incorporate a chemical exfoliator or you risk sun damage.
3)
Less is more! Don't slop this on your face or soak a cotton pad in it, a little goes a long way and you'll be kicking yourself if you apply way too much and have to wait 20+ minutes for it to sink in. Use a shake or two and add more if needed but go easy.
4)
Expect some irritation initially. Chemical exfoliants can be harsh and rough even on sturdy skin and you have to give yourself time to adjust. Over-exfoliation is a possibility but sometimes just introducing a BHA or AHA into your routine can cause some sensitivity. Don't panic and just be gentle to your skin. Use ceramides (like Cerave Skin Renewing cream) or fatty oils to soothe your face if needed and try to stay away from any harsh products or acids like Vitamin C right after applying this to avoid really burning your face.

Amazing exfoliating toner
Size: 4 Fl Oz
I am almost 40 and have had acne since puberty. I have tried so many products. The products that showed some improvement (like Proactiv) changed the texture of my face. Literally made my face feel like a basketball. I’ve tried some products that I’ll notice an improvement after a week or so, and the it would just stop working. I have never used something that so drastically helped my face in such a short amount of time. Notably, within 5 days my blemishes were almost gone. Within a week, my chin felt smooth instead of feeling the bumps of every clogged pore. The discoloration of my face, such as the redness, hasn’t totally disappeared, but it is improving. My face doesn’t feel oily throughout the day. My skin feels tighter, like I got a facelift. Moisturizer along with this product is important. And it is important to follow the directions and start slowly with this product. Use it every other day for the first week, gradually working your way up to daily and then twice a day. It is a shock to your skin and can dry it out if you go overboard. But for what I needed this product for, it has exceeded my expectations in every way. I couldn’t recommend it more. Just a heads up, it is applied like a toner. I expected a face wash, but it is a liquid that you apply to cotton and rub on your face. I wash with CeraVe SA cleanser, follow it with this, and apply whatever moisturizer you prefer—I’ve been using moisturizer with SPF so as to not damage my skin more than I already have.
