ReFuel! Great Deal, Great Filament
"This 3D‑printed LED lamp core is a great showcase for recycled PCTG. The translucent yellow filament diffuses light evenly while still letting the internal structure show through, giving it a modern, warm glow rather than a harsh hotspot. The vertical ribbing and rectangular cutouts add visual interest and help break up the light, so it looks good both lit and unlit. Dimensional accuracy appears solid and the cylinder sits cleanly in its base and the walls look uniform with no obvious warping or layer adhesion issues. Overall, it’s a clean, functional print that makes smart use of recycled material and feels like a sturdy, practical piece for an LED ambient lamp project."

Made the switch to Pro PCTG
"I'd primarily printed with PLA and made a few attempts at getting into PETG. Because of spool compatibility with AMS and available printer profiles, I decided to try PCTG and I'm glad I did. I have two printers and one is almost exclusively printing PCTG projects now. I did dial in the printing profiles for my setup and results, but the 3D Fuel profiles were a great starting point. I switched my AMS silica boxes over to PCTG too."

Refuel is a risk, not always a reward
"Refuel, I understood the risks of not knowing what colors you would get. The first time I received 5 spools in different blues and greens. So when I ordered 11 spools and they were all identical grape purple, I’m still disappointed even knowing the risks. I’m not sure I will do this again, the price that drew me to it isn’t worth sitting on 11kg of grape purple."

Better than PETG. Deep rich colors and consistency
"This has become my new go‑to filament since I got into the hobby. It improves on PETG in most of the ways that matter, but without the usual stringing or finicky print behavior. The Benchy shown was printed on a Bambu H2D at 0. 16 mm layer height, before I even calibrated or dried the filament, and it still came out with clean lines, consistent extrusion, and a deep, rich color. I’m already planning to buy more. I’d love to grab one of every color they make, but I’m forcing myself to show a little restraint."

Amazing color and finish
"The 3D-Fuel Pro PCTG just looks good clean lines, rich color, and that nice wet gloss that makes the parts feel a step up from basic PETG or PLA. The yellow Refuel lattice cup has this almost injection-molded vibe: the pattern is sharp, the walls are even, and the gloss catches light in a way that makes the geometry pop instead of hiding it. The Grape Purple and Toolbox Teal pieces show off how well this filament takes pigment, solid, saturated color with no chalkiness, plus a smooth sheen that runs consistently across curved and flat surfaces. Overall, it has that “premium plastic part” look, glossy where you want it, crisp edges, and a finish that makes even simple utility parts feel like product, not just 3D prints."

3D-Fuel Gun Metal Blue PCTG Review
"3D-Fuel’s Gun Metal Blue PCTG is the standout of this print. It delivers a rich, dark blue-gray tone that reads almost like powder-coated metal under normal lighting, while still preserving enough depth and sheen to make the surface visually interesting. On a large, flat-sided functional print like this case, the color remains consistent and avoids looking washed out or overly glossy. Printed on a Bambu H2D with a 0. 06 HF Tungsten Carbide nozzle using the latest 3D-Fuel PCTG profile, the filament produced impressively uniform walls and clean, sharply defined features. The broad exterior panels show controlled extrusion and a refined layer finish, while small functional areas hinges, latch mounts, edge details, and the interior retain crisp geometry without obvious roughness or inconsistent texture. The material is especially well suited to parts that need to look engineered rather than decorative. Gun Metal Blue PCTG gives the finished case a durable, industrial appearance, and it does so without hiding the quality of the print beneath excessive gloss. The result is a strong example of why PCTG is such an appealing choice for substantial functional prints."

Fantastic stuff
"Re-Fuel prints just like the normal PCTG, i. e. excellently, and it’s a great value when color isn’t important. My understanding is that it’s mis-tints and color transitions, so you really could get anything. I’ve received dull gold, purple, untinted (i. e. , more or less clear) transitioning to gray mid-roll, and orange."

Better go-to than PLA
"Pro PCTG is my standard filament. It’s easy to print, possibly more so than PLA (for me at least), and the results are excellent. Better than PETG any way you compare it. Good thing Fargo is so far out of my way or I’d have some trouble keeping to my budget. I think it’s also worth noting the authenticity of the company demonstrated in its YouTube videos. No slick salespeople or “entrepreneurs”, just a guy talking knowledgeably and transparently about a product he clearly cares a lot about. The awkwardness and rough production values are a big plus in my view because they scream credibility."

Calling this glow in the dark is a stretch
"Initially, I was very excited to use a glow in the dark PCTG filament that was made in the USA but this barely even glows. I had several items sitting on my work bench made in various glow in the dark filaments when I noticed that the 3D Fuel one barely even glows after I shut off the lights in my workshop. All the Chinese brands that I tried put 3D fuel to shame with how well they glow."

Clean reliable prints
"Switched to Pro PCTG Midnight Black for some Ubiquiti camera gang boxes. After drying, the prints came out smooth, dimensionally accurate, and completely free of defects. After wrestling with PETG for so long, this feels like a whole new lease on life."
