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.

Destroyed in under 10 minutes
Size: 9 in, Color: Large Bone
I bought 2 of these toys, one for my 9 year old great dane who isn't an aggressive chewer, and one for my 6 month old puppy who is average. In less than 10 minutes both were destroyed and my dane managed to swallow a good chunk. I wasn't surprised when they both had small holes on the ends and started pulling the stuffing out. The stuffing and squeakers were confiscated immediately, but I let them keep chewing. By the time I came back from throwing the insides away, both dogs had chewed the toys in half and my dane swallowed a chunk when he saw me coming. The puppy was going to do the same thing, but luckily we're working on his "drop" command so he was excited enough for the bigger payout and dropped it. They didn't just come apart at the seams, the whole toy ripped in half making it too easy to swallow. Neither of them are aggressive cheers and the toys didn't hold up at all. A stuffed animal toy would have lasted longer (and has any time I've allowed it). 10 minutes of playtime is probably too generous , but I'm trying to be fair. If I hadn't been right there watching them, they both would have been able to swallow the whole thing in minutes. Definitely not safe for any amount of actual chewing.

The perfect teething toy for a puppy of any size - apparently indestructible!
Size: 9 in, Color: Large Bone, Size: 9 in, Color: Large Bone
I ordered this product for an overly excitable, destructive corgi chihuahua mix puppy, who was teething. He was a foster and managed to destroy, almost immediately, every toy I had on-hand for him, and toys I picked up at the local pet store. I was very concerned he'd swallow parts of toys, which can lead to fatal intestinal blockages, not to mention extremely high vet bills which I couldn't cover as a simple foster mom. When it arrived, I crossed my fingers that the "Seam Protection - doubled-stitched seams with heavy duty thread" would actually add "extra durability." And I was NOT disappointed! The bone shape of the toy would probably fit comfortably in the mouth of any dog or puppy, as you can see from photo #4. What's coolest about the shape of this toy is the pup can sink all of his or her teeth into it, providing comfort for the entire mouth and not just a few teeth or only one section of its mouth at a time. I was much more experienced as a kitten foster mom, and had had similar difficulties finding teething toys for kittens. This toy is thin and light weight enough that I imagine it could provide relief for little kitten mouths, also, but I didn't get to find out, as my little foster pup chose this as his #1 favorite toy and brought it with him to his forever home. I wanted to know how long it would take before he'd destroy it, though (picture 5 he'd had this Dura-Fused bone toy for a few hours short of one week, and the last photo - you'll see he'd not even undone a small portion of the seam!) Overall I would highly recommend this product for teething babies of almost any species. As far as I could tell it is indestructible. Almost seven days of constant gnawing and he'd not even taken one stitch out, created any tear or rip, let alone, gotten close to being able to swallow the squeaker (always a fear!). I imagine months later, he's still been unsuccessful at ripping/tearing this toy at all. I'd gladly buy again should I foster any dog or puppy - the company lives up to its moniker, Ethical Products, because they've produced a no-frills and apparently indestructible squeak toy which I'd have no fears of leaving with a teething puppy unsupervised. Highly recommended!

Good tug toy
Size: 15 in, Color: Retriever
I have a doberman that shready everything in 2.5 seconds. This lasted a few days so was impressed for the cost. Would buy again as he really liked it.

My dog’s new favorite
Size: 8 in, Color: Squirrel
didn’t expect much for the price but my dog actually loves this thing. It’s tough enough to hold up to regular chewing and the leather gives it a nice texture that’s different from the usual plush toys. He carries it around like it’s his prize. It’s not indestructible and if your dog is a heavy shredder it probably won’t last forever but for moderate chewers it holds up way better than a lot of toys I’ve tried. Definitely worth grabbing again.

Not for gnawers
Size: 11.5 in, Color: Bear
I was hoping this would work for my teenage ACD and save my leather goods from being chewed on. He gnawed on it quietly I was thrilled. But I had to take it from him within a few minutes. Gnawing apparently equals chewing pieces off. Not made for chewers or gnawers. It seemed to be well made, was soft, was actually a fairly good size and didn’t get gross when it got spitty. Just didn’t work out for Captain chaos destructor of all.
