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

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.

Printed on BambuLab X1 using recommended settings. 30mm/s super slow but easy to print and no major defects. Will try stock TPU95 settings next, TPU95 high flow. Overall decent product but nowhere near the feel or ductility of silicone. Printed GoogleTV streamer remote cover as none on the market. Still will buy a silicone version when available.

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.

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.

Received product on time. Package properly protected and no damage.This was the first time using g TPE and it worked great. I did use the recommended settings and had no issues. I had to print with support on one part using PVA . It worked fine, looking forward to buying more

I purchased the skin colored SpiderFlex to print some CGM covers for my wife. I have been using NinjaFlex filament (85A shore hardness) but would like a softer material for this application. The SpiderFlex claims to be 75A which should be much softer. Unfortunately, it is not. In softness it seems very close to, or maybe a little bit stiffer than the NinjaFlex. As far as elasticity goes, it is terrible. If I stretch the print more than just a few percent of its shape it deforms and will not spring back to its original shape. The NinjaFlex has no problem here and will allow significant stretching without permanent deformation.On the good side, the color is perfect for skin type applications and the matte finish looks good. The SpiderFlex printed well at 230C with very little stringing for flex material and had no other print problems at all (on a PRUSA MK4).
