Review on Dimensional Polyamide Filament Consumables by OVERTURE by Kevin Pirlet

I have a CoreXY machine that I've been experimenting with high temperature thermoplastics with recently and the nylon is brand new to me and i see this for about $30 i thought it would be nice to try and have some fun and i enjoyed it. Don't get me wrong this filament isn't exactly easy, or as easy as others say you're in trouble unless you have a really expensive printer already set up for nylon, that's how this type of plastic works . , but once you print it, you get an incredibly durable and beautiful piece that's worth the effort. Let's take a look at some of the issues I encountered and how I fixed them. The first problem I had was that the filament was too fibrous and made popping noises when extruding. Any seasoned printer geek can tell you that my filament was wet and needed to dry out, which I did by placing it on a glass plate and baking sheet in the oven at 180F overnight, dip deeper if you're more confident want. Next, when printing over both the pie sheet and the Ultra base style at 80C, the detail was always warped in the middle of the print. This was solved with two fixes: First, to make the parts stick better I went to McMasters and ordered a 12x12 1/16 blue Garrolite sheet (link below) and attached it with the appropriate 3m high temporary adhesive sheet (link below) . ) significantly increases the adhesion of the parts. It's also worth noting that McMaster offers these sheets very cheaply and ships them very quickly, such an amazing treat I've found in my travels. The part is heated to a build plate temperature above the glass transition temperature of the plastic, making it soft and easily deformed. Luckily, Garrolite is a great material for nylon prints as it's almost as sticky in the cold as it is in the heat. This is good because the first layer of the print with all the fine details and lines should print well at higher temperatures (60-80°C) but after that you can lower the temperature below the glass transition temperature of nylon ( I set the temperature successively Layers in to about 45-55 degrees and after that the part stays strong and resists its own deformation.Yes I know the real solution to this problem is a heated chamber and I'm just creating internal stresses.but a heated chamber came out of the question for me, and the meat was better than that no. next thing was just the fibrousness of the thread, mainly because it's softer than pla and petg and what you have, so even though I had a direct drive, I had to check the retraction length Increase speed and speed a bit and make sure your comb/erase settings are enabled correctly Also you can see in some images that the top surface is deformed t. The layup doesn't look great because nylon isn't the best when it comes to bridging (that's what the overlay print layers need to sit on top of the infill) so the gaps in the infill are clearly visible at the top. This can easily be fixed by increasing the number of top layers or the infill percentage. After these corrections, this filament started to print some very nice details and now I am very happy with their finish (Corexy advantages with linear guides). . Also, the filament reminds me of carbon fiber infused filament in appearance, it's a bit matte with some shine, which you can clearly see in the details. -Metal tip, hardened steel tip and preferably geared extruder. I am using a BMG extruder connected to an e3d v6 solid metal hotend. Here are my current printer settings: Line width: 0.4mm on outer walls 0.5mm everywhere on standard nozzle 0.4mm Speed: 25mm/s on outer walls 70mm/s everywhere Fill: 40% (for roof quality) Nozzle temperature: 260 °C Heating layer temperature: 80°C in the first layer, 50°C in the remaining layers Retraction: 3mm at 40mm/s (on bmg direct drive with e3d v6 hotend should be 7-8mm at 45mm/s Bowden ) Cooling fan : no, minimum coating time 20 s. Layer height: 0.2 mm. Z hops: no. All other settings can be kept in stock. -garolite-g-10-fr4-sheets-and-bars/ Here is the adhesive sheet: https://www.amazon.com/Adhesive-Transfer-Double-Printer-Weupe/dp/B07BK8PHZK/ref=sr_1_12?crid= 3M87LNGA7A3KR&dchild =1&keywords=Adhesive%2Btransfer%2Btape&qid=1603090828&sprefix=Adhesive%2Btrans%2Caps%2C208&sr=8-12&th=1Happy printing!
