Specifications on Allowable Shipments of Lithium Batteries

Earlier, I had made a post regarding the prohibited shipment of batteries containing lithium, such as coin-cell batteries:
Batteries *not* included? ūüôĀ

After a review of USPS guidelines for allowable shipments, I can safely say that is no longer necessarily the case:
349 Miscellaneous Hazardous Materials (Hazard Class 9)

It seems that bulk shipments of more than 4 batteries, or more batteries than necessary to operate a device, must be marked with fire hazard warning stickers. Since each item is only shipped with enough batteries to operate them, this is no longer a problem. Therefore, USPS will be used again for all shipping needs, as previously considered.

I apologize for any inconvenience this may have caused in the meantime.

Success! The drawing for this print successfully converted over into an STL file, and was successfully “sliced” into a tool path for the printer. Each of these coins can be produced for various products, e.g. pins and boutonnieres, ribbon medals, challenge coins, and so forth. They have a $5 value per coin by themselves, but I may give them out as takeaways for the first 20 customers at a trade show or convention.

With this successful test, I am pleased to say that the Da Vinci printer is now available for use in commissioned works! Stay updated here for stock items that use this new technology!

Front View of Makey, arms down w/ supports.

With this third print, I downloaded a freeware sample file of the mascot of MAKE Magazine, “Makey”. The first attempt was going to be a faithful duplication of the robot in three dimensions, with his arms down. This print took about 28 minutes and used about 1.366 meters of ABS filament.
Unfortunately, all 3D prints make an object from the ground level up, so I had to add supports to act as a scaffolding while the arms and shoulders were printing in midair. The supports were laid on too thick, and I snapped an arm off trying to clip them. Oh, well, try again…

The second attempt has Makey raising his stubby (though still frangible) arms in triumph, as he is printed with no supports to hold him down, er, up! This version of the print took 36 minutes and 1.374 meters of filament. Gauging the print as an example of the details that the Da Vinci 1.0 can produce, I’d say it’s about what I’d expect from an inexpensive printer that can use ABS. Not the best on the market, but good enough for my intended purposes.

For those who seek to make their own Makey and test their own 3D printer’s capabilities, he can be downloaded in all versions at¬†

Up next, I will attempt to create, compile, and print my own file, from a rendered drawing made on Autodesk software. If that can be resolved successfully, I may be ready to take commissions!

A larger and more complex sample print, the Star Vase was printed in 1 hour, 48 minutes.
It required 8 meters of ABS filament. I actually thought it would be bigger, and perhaps flare out at the top. The walls are only one print width thick (about 1 mm).

I will attempt to upload an STL file next, and if that is successful, I will attempt to make my own STL file from an OpenSCAD model.

After some false starts and puzzlement, I achieved success with the new Da Vinci!
This is an example of the Key Chain sample print. It took 34 minutes, and 3 meters of ABS plastic filament to make. I’ll note that here for¬†reference.

Now that the device is up and running, I will try a larger sample print before attempting to upload some of my own designs. Fortunately, a freeware drafting program called OpenSCAD should allow me to design some of my own parts.

The work envelope for the printer is only 7.8 inches cubed, so for large constructs I would have to print out smaller sub-components to be assembled by hand. Since most of my existing stock consists of small items, this should suit my purposes for the foreseeable future.

Sabins Gadgeteering Lab now has a decent, medium-range, 3-D printer.
The Da Vinci 1.0, made by XYZPrinting, was acquired earlier today and now has a place at its own workbench. After some careful re-reading of the instructional manuals, it will be powered up and run through its operational checklist, including some demo printing. Updates to this status will be posted here, including when we will begin taking orders for printed items.

Batteries *not* included? :(

It has come to my attention that lithium batteries, even coin-cells, are considered hazardous materials when sent through the US Mail. There is a risk of them rupturing when traveling by air to their destination, as most cargo holds are insufficiently pressurized and/or temperature-controlled to prevent this. Since the additional expense of using only a ground carrier would not justify the inclusion of said batteries, I have decided to allow customers to purchase said batteries in their own locations and subtract any cost of batteries from the prices of all items, whether in stock or on commission. I apologize in advance for any inconvenience that this may cause.

Unexpected Fame

I was laying down for a rest the other evening, when my lady exclaimed in calling my attention to the following web magazine article:

That’s us in our Elseworlds Lantern cosplays that you see in the cover shot, photo and article credit to Jason Biundo. Our costumes, about 50% premade outfits, were altered by ourselves to suit our roles as “The Green LanTron” (sorry, Mickey), and the “Sinestro Corps JigSAW Acolyte”, complete with hypodermic of knockout serum for abductions. This is actually the first appearance for both of us in a local publication, so it’s kind of a really big deal.


Our thanks go out to Mr. Biundo, and the staff of 614 Columbus magazine!
