  • 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 simple to use as you could hope for.

  • Announcing the 3D SubReddit Contest Winners

    We recently held a contest on the 3D printing subreddit of Reddit to bring attention to the growing 3-D printing industry while also encouraging designers, 3-D printing fanatics and beginners to generate creative ideas to print with filament based 3-D printers. The goal of the contest was to create a space for participants to brainstorm design ideas to use with a 3-D printer. Prizes included an amount of Lumi-Cord or a gift card to ProtoParadigm.

  • 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 LumiCord

    LumiCord 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 Printers, and so, LumiCord was born.

  • Bill Me Later through PayPal

    Did you know that when you buy from us using PayPal, you can spread the cost across multiple payments interest free over time?

    Maybe you've been eyeing our printer filament and wondering if you could get more time to pay. Well, now you can enjoy your purchases and choose your payments with Bill Me Later through PayPal.

    It's that easy, because Bill Me Later is available at our online store! It's a service that you can add and link to your PayPal account, and it's convenient in many ways:

    • It's easy to apply for and easy to use. You enter your birth date and the last four digits of your social security number to determine if you're approved. Once you link it to your PayPal account, Bill Me Later is available to you during the checkout process at our online store; you won't have to use any plastic or account numbers or endure any long waits.
    • It's a flexible, reusable line of credit. With some of its special financing offers, you choose how you want to pay with Bill Me Later-- in full, or with payments spread out over time.
    • It still protects you through PayPal's Purchase Protection Program, so you don't have to worry about the security of this payment.

    And please don't forget that payment through Bitcoin is also an option! We hope that these additional services make your customer experience at our online store even more easy and pleasant.

  • Lots of Filament Back in Stock!

    As evidenced by the number of products that have been out or stock recently, our extended Summer Sale has been a hit.  As a way of thanking our loyal customers, we have decided to keep our sale prices alive and now have a number of products back in stock.

  • 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, or that people using them in printer kits are just trying to extort more money from you.  We'd like to contribute to this discussion and mention some of the reasons we feel leadscrews are a better choice (and worth the cost) for this application.

  • How Do You Use Polyimide Tape?

    At our lab, we find frequent uses for the wider rolls of our polyimide tape. However, we've become curious about customer uses of the thinner rolls of polyimide tape-- particularly the 10mm and 20mm widths. We'd love to hear from you, our customers, on your uses of these widths.

    And on that note, we'd enjoy commentary about your preferred width. For example,

    • Do you prefer a single wide roll or multiple thinner applications for your printer bed?
    • Do you want your tape to be precisely the width of your printer bed, or thinner, or wider?
    • Are there non-standard widths you would have a use for?

    Please let us know if you have any suggestions. As always, we thank you for your feedback!
