Our 3D Printed Items and Licensing:

Many of our 3D printed items are shared under what's called Creative Commons. Think of Creative Commons as a way for creators to let the public use their work freely, sometimes with certain conditions. For our Creative Commons items, you're generally welcome to reproduce them and even use them to sell your own products commercially.

We also offer some designs specifically intended for commercial use. For these, we've either obtained a special license from the original seller allowing us to sell them commercially, or the designer has directly granted us the rights to do so.

Finally, some items are our original creations, designed by Blue Raven Underground. For these, we retain all rights, meaning they cannot be reproduced or sold without our explicit permission.

Understanding 3D Printing:

A Beginner's Guide

3D printing, also known as additive manufacturing, has revolutionized how we create objects. Instead of traditional methods like carving or molding, 3D printing builds objects layer by layer from a digital design. This process offers incredible design freedom, customization, and efficiency for various applications, from prototyping to creating finished products.

How Does 3D Printing Work?

The 3D printing process generally follows these steps:

1. 3D Modeling: The process begins with creating a digital 3D model using Computer-Aided Design (CAD) software. This model serves as the blueprint for the final object.

2. Slicing: The 3D model is then "sliced" into numerous thin, horizontal cross-sections using specialized software called a slicer. This software generates instructions (G-code) that the 3D printer can understand.

3. Printing: The 3D printer reads the G-code and deposits material layer by layer, following the instructions from the sliced model. The layers fuse together to create the final three-dimensional object.

4. Post-Processing (Optional): Depending on the printing technology and material used, the finished object may undergo post-processing steps like removing support structures, sanding, painting, or polishing to improve its appearance and functionality.

Common 3D Printing Technologies:

Several 3D printing technologies exist, each with its own advantages and disadvantages. Some of the most common include:

• Fused Deposition Modeling (FDM): This is the most widely used consumer-level 3D printing technology. It works by extruding a thermoplastic filament through a heated nozzle, depositing it layer by layer onto a build platform. FDM is relatively affordable and versatile, making it popular for hobbyists and small businesses.

• Stereolithography (SLA) and Digital Light Processing (DLP): These technologies use liquid resin cured by a light source (laser or projector) to create solid objects. SLA and DLP offer higher resolution and finer details compared to FDM, making them suitable for applications requiring precision and smooth surfaces.

• Selective Laser Sintering (SLS): This technology uses a laser to fuse powdered material (typically nylon or other polymers) layer by layer. SLS is capable of producing strong and durable parts without the need for support structures, making it suitable for functional prototypes and end-use parts.

Common 3D Printing Materials:

A wide range of materials can be used in 3D printing, each with unique properties. Here are a few common examples:

• PLA (Polylactic Acid): A bioplastic derived from renewable resources. PLA is easy to print, relatively inexpensive, and biodegradable under industrial composting conditions. However, it is sensitive to heat and not dishwasher safe. Warping can occur above 140°F (60°C). Proper care involves hand washing with lukewarm water and mild soap, avoiding prolonged exposure to direct sunlight or high temperatures.

• PLA+ (Polylactic Acid Plus): An enhanced version of PLA with improved strength, toughness, and impact resistance. Like PLA, it is biodegradable under industrial composting conditions but not in home compost. It is also not dishwasher safe and warps above 140°F (60°C). Care instructions are the same as for PLA.

• PETG (Polyethylene Terephthalate Glycol-modified): A petroleum-based thermoplastic known for its strength, flexibility, chemical resistance, and impact resistance. PETG is recyclable but not biodegradable. It is generally considered top-rack dishwasher safe, but hand washing is recommended for intricate designs. Warping can occur above 170°F (77°C). When printed with a stainless steel nozzle, PETG is considered food-safe under normal use.

Addressing Imperfections:

Due to the nature of 3D printing, minor imperfections like layer lines or slight surface variations are sometimes visible. These are inherent to the additive manufacturing process and do not typically affect the functionality or durability of the object. We thoroughly inspect and clean each item before it ships to minimize these imperfections.

Our Commitment to Quality:

Your satisfaction is important to us. We strive to provide high-quality 3D printed items. If you are not completely satisfied with your purchase for any reason, please contact us so we can assist you.

The Future of 3D Printing:

3D printing continues to evolve rapidly, with new materials, technologies, and applications constantly emerging. From personalized medicine and customized prosthetics to rapid prototyping and on-demand manufacturing, 3D printing is transforming industries and empowering individuals to create like never before.

About Us:

For over 25 years, we've been navigating life's adventures together – the laughter, the challenges, and everything in between. We're Melanie and Rob, proud parents of two wonderful children (and one angel always in our hearts), and devoted owners of our furry companion, Poe.

Family time is everything to us, especially when it involves cozying up for a good show. We share a love for humor and find joy in the everyday moments.

Blue Raven Underground was born from our desire to blend our passions and work side-by-side. Melanie brings the artistic vision, while Rob handles the technical expertise. We're excited to be building something together, doing what we love.

Shipping:

You might notice our shipping costs are based on weight here at Blue Raven Underground. This approach allows us to be as fair and transparent as possible. For a small business like ours, every penny matters, and by calculating shipping based on the weight of your order, we can keep costs down for both of us, ensuring you get the best possible value with each item(s) purchased.

We're eager for your Blue Raven Underground goodies to reach you! Most orders take wing via USPS and typically arrive at your doorstep within 3-5 business days after leaving our secret underground lair. Like a swift raven, we aim to get most orders soaring out the next business day. A little heads up: orders placed after 11:00 AM EST on Fridays will have their flight preparations begin the following Monday.
