Back in November of 2021, I received my Makerbox 16 Everything subscription. Unfortunately, I fell behind on these boxes due to building out a new shop and backing up orders. There will only be one more Makerbox before I am fully caught up! The Everything box includes four easy-to-print filaments (Makerbox Easy) alongside four more advanced filaments (Makerbox Explorer).

Makerbox Easy Prints

Polymaker provided four samples of PolyTerra PLA for the Makerbox Easy filaments. I’ve printed PolyTerra filaments. Actually, PolyTerra PLA was featured in Makerbox 13. I had good results from those prints and expected the same here. Here is what Polymaker says about PolyTerra PLA:

PolyTerra PLA samples

The four colors included in the Makerbox Easy collection are Rose, Sapphire Blue, Charcoal Black, and Fossil Grey.

The recommended print settings for this filament are:

  • Hotend Temp: 180-230C
  • Bed Temp: Room-60C
  • Speed: 30-60 mm/s
  • Cooling: Yes
  • Other: Dry before use for best results.

Before printing the samples, I put them in the dehydrator at 55C for six hours. I printed all four samples on either an Ender 3 Pro or an Ender 3 V2 with stock hotends. I printed the temp towers in a range of 200C to 220C. The test models were all printed at the height of .16 mm. The temp towers were all sliced using CURA, while the test models were sliced using a mixture of Cura and PrusaSlicer.

Rose PolyTerra PLA

Below is the print result from Rose. The temp tower printed quite nicely. There was some slight stringing in the back of the tower. There were also a few spots of what appeared to be under-extrusion, but that did not show up later in test models. I chose to print the test models at 210C.

Rober Rollin designed the Penelope Pussycat model. I was pleased with how this model turned out. There was some very slight stringing between the two ears, but the print is almost perfect otherwise.

The color of the model is a little more pinkish than the picture. But I had a hard time keeping the detail and color, so I decided to focus on detail.

Sapphire Blue PolyTerra PLA

Up next is Sapphire Blue PolyTerra PLA. The temp tower had what appeared to be some under-extrusion spots on the top two layers. There was also a little bit of stringing on the top level. I chose to print the test model at 205C based upon the tower.

A Captain America Tiki model by Hex3D was used to test the filament. The print ended up great. The little details in this model showed up great. There was no sign of under-extrusion or stringing on the test model.

Charcoal Black PolyTerra PLA

Charcoal Black PolyTerra PLA was up next. The temp tower printed perfectly. There was no stringing and the bridges were solid.

The Dark Knight model designed by Rober Rollin printed nearly perfect. The details on the Dark Knight’s abs are amazing. The layer lines on the model are almost invisible. This was probably one of the better black filament samples I’ve ever tested.

Fossil Grey PolyTerra PLA

Up last for the Makerbox Easy selection is Fossil Grey PolyTerra PLA. The temp tower printed nicely. There were a few strings on the back and some underextrusion on the top level, but otherwise it was great. I chose 210C as the test model hotend temp.

Rober Rollin created the Cable model. The model printed perfectly. All of the little details in his uniform look great. Plus, I happened to drop this model on my shop floor. It bounced a bit but never cracked or broke.

I had excellent luck with the PolyTerra PLA samples. In particular, I found the Charcoal Black to be one of the best black-colored filament samples I’ve ever printed.

Makerbox Explorer Prints

Included in each Makerbox are the Explorer filament samples. Explorer contains samples of various filament types from a variety of manufacturers. I usually determine whether a filament is suitable for upcoming projects from these samples.

The test models were all printed at the height of .16 mm on and Ender 3 Pro or an Ender 3 V2 with stock hotend. The temp towers were all sliced using CURA, while the test models were sliced using either CURA or PrusaSlicer.

Karnak Sandstone PLA from Paramount3D

Up first in the Explorer selection is Karnak Sandstone PLA from Paramount3D. The cool thing about this filament is that it has flecks of black. These flecks make the printed samples look like granite countertops.

The recommended print settings for this filament are:

  • Hotend Temp: 190-220C
  • Bed Temp: Room – 60C
  • Speed: Not Listed
  • Cooling: Not Listed
  • Other: None

Due to the black flecks, I considered putting a .5mm or .6mm nozzle in the printer. However, I opted to keep a .4mm nozzle in to see how well it would do.

I printed the temp tower in a range from 195-215. The temp tower printed absolutely perfectly. The tower looks great, and as I noted above, it looks like granite. Therefore, I decided to use 205C for the test models based on the tower.

I printed a nice test model of a wax stamp for a buddy of mine. He wanted a stamp that looked unique. This filament was perfect for that use. Unfortunately, I forgot to take a picture of the stamp before mailing it out. So, I used the tiny remaining filament to print the base of that stamp (pictured below). It turned out smooth as heck, and just like the tower looks like a piece of granite.

Red PVB from YouSu

Next is Red PVB from youSu. This filament has an excellent additive to give it a “gorgeous luminous star appearance.” I don’t recall ever printed PVB. Here is what the material with the sample has to say about PVB:

PVB has impressive mechanical properties. The layer bonding after polishing can be as strong as injection molded parts. Can be easily sanded and polished to a shiny, smooth surface.

This stuff sounds great for some of the cosplay items I print.

The recommended print settings for this filament are:

  • Hotend Temp: 190-220 C
  • Bed Temp: 40C
  • Speed: Not Listed
  • Cooling: 100%
  • Other: Bowden retraction = 4mm, Direct drive = 1.5mm

I printed the temp tower in a range from 195-215 C. Since I have a Bowden setup on the printer used, the retraction was set to 4mm. The temp tower had a lot of stringing on the top two levels. However, the towers printed perfectly, and the bottom two bridges were almost flawless. Based on the temp tower results, I printed test models at 200C.

I chose to print some Ecto Goggle parts designed by Ghostbusters Gear to test the filament. The two shafts printed perfectly. I will use these shafts in a couple of goggles I am building. The dial also printed perfectly. I left the supports for the dial on for the picture. The supports printed great, and I was able to remove them quickly.

White PolyMax PC-FR from Polymaker

The third filament is White PolyMax PC-FR from Polymaker. I love testing filaments like this, which I had never heard of before. Here is what the card with the samples has to say about PC-FR:

PolyMax™ PC-FR, creation from Covestro’s Makrolon® family, could achieve V0 performance in the UL94 flame retardancy test and displays excellent toughness, strength and heat resistance. This filament opens new applications in the automotive, railway and aerospace industries.

The possibilities of this filament sound incredible.

The recommended print settings for this filament are:

  • Hotend Temp: 250-270 C
  • Bed Temp: 90-105 C
  • Speed: 40-100 mm/s
  • Cooling: Off
  • Other: Heated chamber recommended (90-100 C)

I don’t have a heated chamber. So instead, I printed this in an enclosed Ender 3 Pro. I turned the bed on to 110C about 30 minutes before printing. I was hoping that would make the inside of the enclosure hot enough to print the model.

I printed the temp tower ranging from 250-260 C with a bed temp of 100 C. The bottom half of the tower printed rough. The upper bridge seemed a little rough. But it all was strong. And the middle bridges printed perfectly. So based upon the temp tower, I chose 257 C to print my model.

The model I printed was a scaled-down control panel for Marvin the Android designed by Ian Hughes. The bottom layer was rough around the outer perimeter. I should have gotten my Z height better determined for the filament. However, above the bottom layer, the control panel printed great. It seems very sturdy. I will employ a little sanding on the bottom edge and utilize the model in a scaled-down Marvin project I’m currently working on.

Silver Elixir from Polyalchemy

Last but not least is Silver Elixir from Polyalchemy (sold through Printed Solid). This is a cool Silk PLA I’ve had good luck with in the past.

The recommended print settings for this filament are:

I printed the temp tower in a range from 200-200C. The temp tower printed great overall. The bottom level and bridge were almost perfect. Based on the tower results, I chose to print test models at 200 C.

The models are much shinier than the picture below shows. But I was trying to focus more on detail and get rid of the sine (which is quite impressive).

The test models are for Ecto Goggle parts designed by Ghostbusters Gear. The details printed perfectly. These will be used in an Ecto Goggle build I am working on in my free time. There are supports under the end cap, and I could remove them quickly. The band attachment looks good, but I would only use that band attachment for display purposes.


Makerbox 16 did not disappoint. All of the filaments were interesting. I think the winner of this bunch came from the Easy collection. The Charcoal Black PolyTerra PLA is genuinely one of the best results I’ve had from a black filament. A very close second is the Karnak Sandstone PLA from Paramount3D. It just looks like granite, and that is impressive. But then all of the other filament samples were great as well. Lineups like this are why I will continue to subscribe to Makerbox.

Song of the Day: A Hero Forms

Due to how well the Dark Knight printed, I thought this video was appropriate. This is Batman Arkham Knight Song “A Hero Forms” (MUSIC VIDEO) – TryHardNinja feat JT Machinima.

Bonus Song: The Sound of Silence

For some reason The Sound of Silence comes to mind when I think about Batman. This Disturbed cover the Simon and Garfunkel song is just amazing.
