Filament Samples

All filament samples are at least 20 meters in length (actually more, I increased the length to eat up the extra filament being left behind on the rolls)


PLA Pro Select - Ivory Silk

Extrusion Temp: 205 to 225C
Bed Temp: 35-60C

FilamentOne is starting to produce silks! I haven't printed with too many silks yet, but this one printed like butter! Like the warm butter melting over your corn on the cob at your weekly summer cookouts!

H & H 3D Plastics

PETG - Natural or Black

Extrusion Temp: 235 to 245C
Bed Temp: 0-68C

H and H was in my very first UFO and while I tried to get them in last month, I'm still happy I was able to get them in this month! Their PETG prints really nice and I'm glad to help introduce them more to consumers rather than their normal commercial customers.

Extrusion Temp: 190 to 220C
Bed Temp: 0-60C

In Florida a staple of summer is the plethora or Oranges everywhere, and this color reminded me of the juicy round oranges waiting to be devoured. 3DXTech offers many different types and brands of filament with excellent quality.

PLA - Marble

Extrusion Temp: 190 to 220C
Bed Temp: 0-60C
Speed: 50-90mm/s

While the color of the filament isn't "red", the black specs made me think of watermelon seeds. This is the first marble filament I've tried and the first time I've used Zi-Rui and it printed wonderfully.

Bonus Accessory!

Four Ziplock Mylar Bags and 4 20g Silica Packs from Snolabs

These large and Extra Thick (7.8mil) Ziplock Mylar pouches are perfect for filament storage.

All filaments absorb moisture from the air and should optimally be kept around 40-50% humidity. Dry filament always prints better than filament left exposed to the environment. These bags are perfect for keeping your filament dry between uses and do not require heat sealing. They also stand up for easier storage and sorting.

Includes a 20g color-indicating reusable desiccant pack to help keep your filament dry.

** Note, I noticed that the humidity of Florida started changing the colors indicating that they had absorbed some moisture already. A dry pack should have yellow beads, a wet pack has green beads. These packets are rechargable

-  You can use either oven or microwave for reactivation.

  1. Oven: Bake packets or beads for 0.5 - 2 hours at 200 - 250F.
  2. Microwave: DEFROST packets or beads for  7-12 minutes.

* Start with the least amount of time and increase the time if color is not fully returned to the original state..

* Reactivation time varies depending on the saturation level of beads, and types of microwave.

* Many microwaves do not let you choose time for Defrost mode. Instead, they want you to enter the weight and the microwaves automatically calculate the time for you based on the weight.  You can enter several weights and choose the weight that gives you the closest time to 7 minutes.

Bonus Project!

Hydraulic Robot Arm

I thought this would be a super fun project for those with kids, though me personally I had a lot of fun putting it together during a live stream and trying to pick up chips and dipping them in my chip dip.

The UFOs contained:

  • Six 10ml Syringes
  • Approx 4 1/2 feet of tubing

* NOTE: The 3D Printed parts were designed for 5ml syringes, however if you print the parts at 120% they fit the 10ml syringes perfectly.

** NOTE: The pins/pin holes are noted on the thingiverse page to need some adjustments. I personally took a soldering iron and made the holes bigger. Additionally, the sliders in the "remote" need some sanding down.
