General printing guidelines *

Nozzle size: ≥ 0.4mm

Layer height: ≥ 0.2mm

Experience level: Beginner

Print temp: ± 215 - 235° C *

Fan speed: 50-100%

 

Heat bed: ± 0 - 60° C

Enclosure needed: No

 

*) Above displayed settings are meant as guidance to find your optimal print settings. These ranges in settings should work for most printers, but please do feel free to experiment outside these ranges if you think it is suitable for your printer. There is a lot of different type of printers, hot-ends and printer offsets that it is extremely difficult to give an overall one-size-fits-all setting.

*) If blobs/lumps form around the nozzle then your print temperature is too high.

Post processing MetalFil - Classic Copper

  • Brushing and/or sand grinding - Once printed MetalFil - Classic Copper objects can very easily be brushed with a brass brush or sanded with fine-grit sandpaper. By brushing and/or sand grinding your printed object you will brush/shine up the high concentration of copper powders.
  • Build-in white polish feature - After being brushed and/or sanded MetalFil - Classic Copper will reveal its white polish feature. A very thin white layer/haze on your object will now allow you to easily polish your 3D print into a beautiful copper object.
  • Professional polishing with a rotary tumbler - Post-processing a MetalFil - Classic Copper 3D printed object with a rotary tumbler will make your FDM 3D printed object indistinguishable from genuine copper casted objects.
  • Patina post-processing - You can create several patina effects on MetalFil - Classic Copper printed objects in just one day time. With an ammonia and soda treatment you can for instance easily create a beautiful ancient green/blue weathering effect on your copper object.
  • Waxing and coating - After every above-mentioned post-processing measure, you can always wax or coat your printed object to get an incredible shine effect. Waxing can be done with products such as beeswax and for coating one can think about products such as XTC-3D.
  • Abrasiveness - Please be aware that MetalFil filaments contain a very high concentration of metal powders, which have an abrasive nature. In general, these metal powders will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. We recommend using nozzles from stainless steel or other hardened alloys.

Nozzle cleaning

When printing with filled/composite filaments it is recommended to clean your nozzle immediately after printing by feeding 15-20cm PLA filament through your nozzle. This will make sure that any potential fillers are flown out of your nozzle. It is even better to use glow in the dark PLA as the extremely hard phosphorous particles are much more likely to scrape out residual waste from your nozzle.

Perfect chair!
Size: 934-Z, Color: Blue, Size: 934-Z, Color: Blue
I have an adjustable-height desk (also purchased from Amazon) and needed a drafting chair for those times when my body gets tired of standing. This chair fits the bill and then some! I put it together myself; it took me about an hour, but would take me about half that next time, since now I know what to do (and what NOT to do!). All the parts were there; there are even spare parts (see photo). All the holes were drilled in exactly the right places, too, which isn't always the case when I buy things from Amazon (my standing desk is a great example). The chair fits me; I'm short (5'3.5"), and often the seats of furniture are too deep for me to rest my feet flat on the floor. The depth of the seat on this chair is just a little over 18 inches, and with the adjustable footrest ring, it's perfect. I don't think a tall or heavy person would fit in it, to be honest. But it's perfect for those of us who are vertically challenged. I love that it glides easily on my hardwood floors and that it turns 360 degrees. The chair comes in numerous luscious colors, so take your pick! It is very sturdy, has good lumbar support, and the seat and seat back are very comfortable. And the arms flip up, which was an absolute must when I was shopping for this chair. I got it on sale, too -- $109.00 -- and I'm delighted with this purchase.

Excellent adjustable drafting chair
Size: 934-Z, Color: Blue
Excellent chair design, extremely comfortable and exceptionally easy instructions to follow making for simple assembly. Love the amply wide cushioned seat and ergonomic backrest. The height adjustment feature works perfectly as well as positioning of the foot ring . Having the ability to raise the arms is also a big plus! I highly recommend this product for attractive appearance, comfort features, functionality and operation. Really nice chair!

Comfortable, stylish, and perfect for long work hours 💗✨
Size: 934-Z, Color: Pink
I bought this chair because I spend a lot of time working and needed something comfortable but also stylish, and I absolutely love it. Since I started using it, I feel much better support in my back thanks to the lumbar support. It makes a big difference, especially during long work hours. The adjustable footrest is also a feature I didn’t know I needed, but now I use it all the time. The flip-up armrests are very convenient because I can adjust them depending on what I’m doing or move them out of the way when needed. The pink color is beautiful and adds a soft, elegant touch to my workspace. It looks great in a modern home office. It feels sturdy, well-made, and very stable. Overall, it’s a great purchase that improved both my comfort and the look of my workspace.

All-around thumbs up!
Size: 934W-Z, Color: Black
So far, so awesome. Easy to assemble, comfortable, arrived quickly and is exactly what I was looking for. I have a tall work bench in my new studio so I needed a chair that we could allow me to sit higher than a regular office chair and allow me to get off my feet after standing on the concrete floor. Plus its a nice looking chair that I am sure will last a long time. I love the flip-up arms and the lumbar support. This is just right!

Perfect Balance of Comfort, Support, and Style!
Size: 934-Z, Color: Black, Size: 934-Z, Color: Black
I’ve been using this chair for a few weeks now, and I’m genuinely impressed with how much of a difference it’s made in my workspace. The mesh back is one of my favorite features—it offers excellent breathability and prevents that sticky, overheated feeling you sometimes get with solid-back chairs, even after sitting for hours. The seat cushion is firm enough to give proper support but still has enough give to keep me comfortable through long workdays. It feels like the perfect middle ground between soft and supportive. The adjustable foot ring has been a complete game changer for me. I use a taller desk setup, and having somewhere to rest my feet makes a huge difference in posture and overall comfort. Whether I’m sitting upright for focused work or leaning back to read, it’s always at the right height. The flip-up armrests are another smart design choice. When I’m typing, I like to have them down for support, but when I’m done, I can flip them up and push the chair neatly under my desk—saving space and keeping things tidy. The casters roll smoothly on both hardwood and rugs, so I can move around easily without scraping the floor or getting stuck. The overall build quality feels solid and sturdy, with no wobbles or creaks. Assembly was surprisingly quick—everything was clearly labeled, the parts felt durable, and it only took me about 20 minutes from opening the box to sitting in the chair. The sleek, modern look is another big plus—it blends in perfectly with my home office décor without feeling bulky or taking up too much visual space. If you’re looking for a chair that combines comfort, ergonomic support, durability, and style, I can’t recommend this one enough. It’s equally great for work, studying, or just relaxing at your desk, and it’s definitely been worth every penny.
