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.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.
