Our new webfront is up and running along with a new company focus and direction. Here are the highlights.

There's a New Manufacturer in Town  

It's us, we're the new manufacturer in town. This is by far the most important part of our new direction, we're at the steering wheel. Which means when you're talking to us, you're talking to the folks designing and making your 3D Printer Filament. 

But Protoparadigm, isn't it hard to make 3D Printer Filament?

It is if you're doing it right, and we've spent the last 18 months designing, machining, coding, and testing custom hardware and software to do so. If you want low grade, over processed plastic filament you're at the wrong place. We're only using the good stuff, and we keep it good throughout the production process.  

And if you disagree with us after using our filament we'll refund your money and say thank you with a smile on our face. Knowing when and how to improve 3D Printer Filament does only good things for us and you. And since we have complete control over the production process we're actually able to do something about it. 

We are dedicated to taking the 3D Printing industry further through purpose-driven materials that expand applications and facilitate a better 3D Printing experience.

Free Shipping? No Way...Yes Way!

We are super stoked to be offering free shipping to the lower 48 states. The standard carrier method will be UPS Ground but expedited options will still be available to those who need filament faster. Just be sure to give us a heads-up through our contact form on anything urgent so we can ensure your package gets out the door before the cut off time. 

100% Money Back Satisfaction Guarantee

Oh, man, there's just so many options out there for 3D Printer Filament. Who should I buy from? Who can I trust?

US! Because if you aren't satisfied with your filament we'll give you your money back. We want to make 3D Printing materials that rock your socks off. So pick up a spool and try it out.

New Spool Weight?

It's not a question. We have a new spool and weight. Well the spool isn't that different, just a little thinner at 2" thick. But we've changed our standard weight from 2LBs to 750grams (1.65LBs). This combination of size and weight allows us to pull off free shipping, offer more exotic colors and materials and STILL lower the cost per pound for standard colors and materials. Buh-Bam!

New Colors and Materials Inbound

Now that we're making our own stuff we want to be very deliberate about what colors and materials we offer. A large focus will be on product families that serve particular groups and applications. 

You'll notice on the front page we have a link to our new gemstone family of translucent and pearlescent PLA and ABS (ABS coming soon).

In the coming days and weeks we will be adding more inventory to our gemstone family, our essentials category and introducing our newly developed ProtoTek Reactive Filaments. Stay tuned, grab some spools and let us know what you think and want to see in the future.

From all of us at ProtoParadigm LLC,

Happy Printing!

Cube Root in OpenSCAD

A while back, I wanted to make a parametric design in OpenSCAD that required the calculation of a cube root for one of the parameters for a volume calculation, but discovered that there didn't seem to be any code for doing this in the wild. I've finally gotten around to an implementation that's about as [...]

Customer Spotlight: 3D Printed Case for Arduino-Based BBQ Controller

We recently learned about a fantastic project that a customer of ours is supporting called the HeaterMeter, and just in time for summer!Conceived by Bryan Mayland, the HeaterMeter is an AVR / Arduino microcontroller-based automatic BBQ controller. Our customer, Tom Kole, wanted to utilize 3D Printing in the process of building his HeaterMeter and originally [...]

Announcing our new LumiCord website!

We’re very pleased to announce the launch of our new division, LumiCord, and its website, at www.lumi-cord.com.The Birth of LumiCordLumiCord is the product of research on high capacity photoluminescent (glow-in-the-dark) 3D printer-compatible materials in the spring of 2013. During that research, it became clear to us that there are uses for an illuminated filament apart from 3D [...]

Accuracy vs Precision and Threaded Rod vs Leadscrews in 3D Printers

Many Personal 3D Printers use threaded rod as a drive mechanism, usually just for the Z-axis, most of the rest use precision leadscrews.  We've seen debate in multiple forums about which is better, and about how much of a difference it actually makes.  We've even heard the argument that leadscrews are a waste of money, [...]

What to do with a 3D Printer: Celebrate the 4th of July in Style!

Fireworks. Celebration. Independence. July 4th.As a kid, my large, extended family always had a 4th of July get-together. We’d head over to my cousin’s, eat a bunch of food, play a game of softball, swim in the pool and finish off the day with our own firework show. Part of the fun was seeing who [...]

3-Screw Bed Leveling and the Importance of a Level Print Bed on a 3D Printer

Achieving and maintaining a level print bed on your 3D Printer is of paramount importance.  High quality prints and reliable printing depend on a level bed, particularly at high resolutions. In this post we'll explain why it's so important, how to achieve it, and what you can do if you just can't get there with [...]

Vapor Smoothing and Polishing PLA with Tetrahydrofuran (THF)

Acetone has been used for some time to treat ABS parts, either by polishing, vapor smoothing, or even using it to stick parts together. Likewise, Methyl ethyl ketone (MEK) has been used to the same effect with ABS. We found Tetrahydrofuran (THF) to be the best option in our assessment, but be warned that there [...]

Weathering of 3D Printed PLA Objects

We've received questions about how 3D Printed parts handle weather and exposure. It's been just over a year since my post about the 3D Printed Garden Tools. The slug trap in that post received the most attention, and was also the most structurally interesting. When spring was over and the great slug war abated, I [...]
