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.

Kids love the newest “Worst” tale-
Format: Hardcover
Kids will love this next book in The Worst series. Awesome, fun, colorful illustrations in this tale with Gilbert the Goblin trying to escape cupids and valentines. Instead of candy for Valentine’s Day give the gift of this book. My students love when Alex Willan has a new book out and are loving this one.

Plenty of fun for Gilbert fans!
Format: Hardcover
As in previous books in the series, Gilbert the Goblin complains about the problems he sees with Valentine's Day, what he calls 'mushy malarkey'. Young readers who don't care for the holiday will find much to relate to in the book. Although, Gilbert's complaints seem a tad trifling. Coconut chocolates are 'Blech'. He seems to have a special issue with the cupid's 'perfect', 'beautiful', and 'luxurious' hair. When Gilbert faces off with a group of cupids, he just barely manages to escape their love arrows, or so he thinks until he backs into a cactus in his own yard and believes he has been pricked by one such love arrow. He then becomes a goblin full of love. He loves his spells, his potions, even himself, but not coconut chocolates. He even welcomes his friends over to celebrate before bidding his pet sock slugs a fond goodnight. Good thing the love spell wears off. This funny book follows the pattern of the previous five books, but the addition of adorable cupids as well as Gilbert's beloved cactuses and pet sock slugs provides plenty of freshness as Gilbert once again (reluctantly) joins in the festivities. Plenty of fun for young fans of the series.

Best way to explore Paris
Format: Paperback
This book is awesome! I enjoyed reading it just as much as my kids did! I love the layout and the way that the book assigns the kids to be secret agents, but defers to the case officers (parents) for the final say. We were in Paris for 1 week and although the weather was less than cooperative, we were able to capture our 100 points and award our 4yo and 7yo their secret agent certificates. I love the fact that you can work on this book in any order and do as little or as much as you want at each attraction. The price was awesome and worth every penny. My 7yo particularly enjoyed the challenges at the Musee D'Orsay and the Louvre and it was a great way to keep those visits focused and entertaining for the kids. My 4yo was a little young to stay engaged with every "mission", but the activities were easy enough that she could help (ex. finding a winter scene in the Musee D'Orsay). I loved that this book engaged the kids but didn't detract from any of our visits (we didn't feel like we had to go "out of our way" to find anything). The only disappointment was that they didn't include Versailles and Sainte Chappelle. I have not only recommended this book to all my of friends traveling to Paris (honestly with or without kids), but I have also already purchased the similar books for London, New York, and Washington DC. Can't wait to see what other cities they add!
