SpiderMaker SpiderFlex Matte Finish Flexible TPE (Matte TPU) 3D Printing Filament - Shore 75A, 1.75mm, 500g (Coal Black)

With an open mind to trying new filaments, I gave this SpiderMaker SpiderFlex in matte black a try. Do note that the price is for a 500 gram spool, not 1 Kg. So, this is an expensive filament. Is it worth it? Here’s what I found: First, the 75A Shore hardness is what piqued my interest — and my concerns. I’ve never used anything this soft in a 3D printer and had no idea what to expect from it in my Bambu Lab X1E which is direct drive, but still feeds from long PTFE tubes to the hot-end on the standard, external spool arrangement. At the same time, I’ve always felt a want for material that prints softer and with more “squish” (like soft silicone rubber) than the excellent, 95A TPU I’ve been using. 75A is about as low as you can go on the Shore A scale before attaining “my pasta noodle has been soaking in hot water for 10 days” unworkability. So, the promise of ultra softness and flexibility is there. Also, note that this is a TPE filament. All TPU are TPE, but not all TPE are TPU. TPE is generally softer and more flexible than most TPU filaments. So far, so good on the promises of “more softness.” I created a custom filament profile in Bambu Studio, using the “Generic TPU” settings as a starting point. I then reduced the volumetric flow from 3.2 to 3, increased the flow ratio from 1 to 1.13, and raised the minimum nozzle temp from 200 to 210 deg C. I printed using a 0.4mm nozzle, 0.16mm layer height, 240 deg C nozzle temp for all layers, and reduced the print speed to 30 mm/s max (and fractions of this). For good measure, I dried the filament at 70 deg C for 12 hours prior to printing. The results impressed me. This SpiderMaker SpiderFlex TPE printed with zero stringing, which is amazing for printing at such high nozzle temps. The surface texture is delicious — it has that signature, grippy “tack” that one gets with soft, silicone rubber. I recommend printing with the smooth PEI plate, which gives a contact surface with a semi-matte finish that is indistinguishable from injection-molded, silicone rubber. Do use glue stick on your plate, otherwise you may have to fight to peel away your printed parts from your build plate. This is a testament to the superior adhesion of this filament. The softness and pliability is definitely there. Do note, however, that if you print thick parts with lots of infill, you will get a stiffer product. I recommend 15% infill max on thicker objects to get that delicious “squish” you / we crave. My application for this material is to print gaskets to give an air-tight seal around the purge chute to keep the heat in my X1E printer chamber and the toxic VOC fumes and aerosolized fiber particles from leaking out (into the air I breathe) when printing with high-temp engineering materials such as PC, ASA, PA, PAHT, PPA and PPS. This requires the ability to achieve a smooth surface finish and enough softness to conform to the irregularities of the contact surfaces. The SpiderMaker SpiderFlex delivers on both requirements. See my attached photos of the custom gaskets I designed and printed for this application. I later discovered that setting “surface ironing” ON in the slicer settings will give fabulously smooth, flawless top surface finishes with this filament. My verdict: SpiderFlex is my new, go-to filament for printing custom, silicone-rubber-like gaskets and shock absorber pads. I enjoy very much working with this new-to-me filament, and highly recommend it. I have experienced no jams in my Bambu Lab X1E printing from an external spool feeding via a one-meter long PTFE tube to the hot-end. Overall, I enjoyed a very pleasant and problem-free, user experience with this product, SpiderMaker SpiderFlex, with perfect results on every print.

The SpiderMaker SpiderFlex Matte Finish Flexible TPE (TPU) Filament in Coal Black is noticeably softer than my other 83A filament, making it ideal for flexible projects. The matte black finish looks great, giving a professional appearance to prints. I use it with my Prusa MK3s+ without any issues, enjoying smooth printing every time. It is a little pricey but i am only using it for small parts/gaskets so it is relatively cost effective. For those wondering about the Shore hardness accuracy, my experience confirms it's spot-on. This filament not only promises but also delivers flexibility and quality in its prints.

I use this filament for light blockers I make and sell for Nreal (Xreal) Air AR glasses (what's pictured). Once you get the setting dialed in a prints fantastically. You WILL need a direct drive printer to get really good results (I've tried on a few non direct drive and just couldn't get it working great). On my Qidi Tech X Max printers I have the temps set to 220 nozzle and bed at 0, retraction at 3mm with 30mm/s retraction speed, retract at layer change, and enable coasting, print speed is at 30mm/s. On my BambuLab P1P's I used the default TPU profile, but changed max volumetric speed to 3mm3/s and retraction to 2mm, same temps as the Qidi. These provide great results with no stringing and easy to remove supports. If you want SOFT TPU that has a great matte finish and have the right printer to print it with, I'd definitely recommend this filament.

As someone with an older Flexion Extruder, I can happily say it's one of the easiest materials I have worked with. That being said, I should mention that my extruder is designed for softer materials and prints at full speed with softer materials without issues. The material is soft and flexible and allows me to print small widgets. I love it.

Update: This is a interesting filament with many quirks. I figured out how to print with it and took a bit more experimentation than usual but I think I got this down. Unlike typical TPU/TPE this stuff still has relatively weak layer adhesion, however, it is still pretty good so long as you're not intentionally trying to rip it apart. This stuff really doesn't like overhangs but if you use a thick layer height or line width you can get some decent overhangs. You'll probably want to print this slower than other brands of TPU/TPE and make sure you run this stuff through a filament drier or it will be impossible to print with. This stuff for some reason seems the hate gluestick and would much rather stick to a PEI sheet or glass. It is still very much expensive for the amount of material you get but there seems to be nothing else like it on the market so I guess that justifies the high price... somewhat. I really want to like this material now that I figured out how to print with it, but the price as well as the difficulty to print with it still bothers me. Old Review: For a TPE it is this stuff is very much not worth the money, even at the nearly 25% discount I purchased this filament for. First off, for a matte filament the prints aren't really all that matte, more of a glossy satin than anything. And for some reason sometimes this filament likes to warp off of the print surface even with a layer of glue stick. This stuff also has terrible layer adhesion and I wouldn't be surprised if it has something to do with the matte finish. The same equivalent hardness TPE from Ninjaflex provided nowhere near this amount of trouble. The only nice thing I have to say about this filament is that it has an unmatched soft touch feel to it that I never experienced in any other filament. But even at the discounted price, at 500g per roll this filament is this way too expensive. let alone at the original price.

This worked well for me. I was looking for something more tacky, and this seems slightly more tacky then TPU (Overture TPU and Fast TPU.) I'm printing a putter grip, and this feels a little more tacky. Printed about the same as TPU. I did print at the recommended speed. I did have a Bed temperature of 55. I had retractions off and can't comment on stringing. I do wish it cost less.

Probably stating the obvious but this filament is much softer than the 95A TPU and NinjaFlex filaments I've used in the past. Perfect for printing tires, gaskets, rubber feet, and the like. The matte finish provides better grip, and it reduces visibility of layers (just like in the photo). This stuff is pricy so be sure to use filament dryers / vacuum storage bags to maintain filament quality over time.

I love this stuff! Feeds great in my Bambu H2D, no issues what so ever! Pliable, strong, seamless! I used it to make a cowl for Comic-Con! I am gonna use it to make a Halloween Mask next!

Sono anni che stampo. Ho provato questo filamento con tutte le impostazioni possibili e su 3 stampanti diverse. Ho consumato la bobina è non sono riuscito a completare 1 sola stampa.

マットなところ以外は評価できない‥‥ TPEとか嘘の説明文はやめて欲しい！ なんだよ（TPU）って全く違うモノを同じなんだよみたいな表記はダメでしょ。 絶対買っちゃダメです！
