13. Post-Processing Your Prints

Anna Kaziunas France Maker Media, Inc ePub

Friction weld, rivet, sand, paint—arm yourself with simple tools and finishing techniques to take your 3D prints to the next level.

Matthew Griffin

Andrew Baker

People often claim 3D printers can “make you anything you can imagine.” Dial up the digital model you want, hit “Go,” and the machine hums to work, producing an object accurately and repeatably. But as an astute eight-year-old pointed out to me when I handed her two of my favorite printed models at Maker Faire Bay Area last year, the results don’t always match your intentions.

“That octopus is red! A TARDIS is not supposed to be yellow!” she wailed, and knocked my offerings away.

While overall shape and mechanical fit are valued more highly than surface treatment in today’s desktop 3D printing, it’s sometimes worth judging a print by its cover.

I’m reminded of advice I got from a pair of industrial design professors at Pratt, after I showed them my print of a fluorescent-green clockwork mechanism: “It is worth enormous effort to make prototypes look like they were created from real-world materials.” Even the most creative engineers and business people will have difficulty seeing your prototype as a machine when it looks like a toy.

2. Anatomy of the Nikon D90

Ben Long O'Reilly Media ePub

In the previous chapter you saw how you can use the Nikon D90's automatic features for easy snapshot shooting. Before you go on to learn about its more advanced shooting features, you're going to take a tour of the camera and learn its parts. The D90 is a complex tool, and the better you know its workings, the more easily and effectively you'll be able to make it do what you want.

The Nikon D90 is an SLR camera, a term you may have come across when you were shopping. SLR stands for single-lens reflex, and those words tell you some important things about how the camera operates.

As the name implies, a single-lens reflex camera has only one lens on it. If you're wondering why a camera might have two lenses, consider a point-and-shoot camera. If you look at the front of a lot of point-and-shoot cameras, you'll see two lenses, one that is used to expose the image sensor and a separate lens that serves as a viewfinder. The advantage of this type of arrangement is that it's very simple to engineer, and it doesn't take up much space, so a point-and-shoot camera can be made very small.

Creating things from atoms is better with bits.

Declare to the world your proficiency in the world of 3D printing with this embroidered skill badge from Adafruit.

There are many useful and inexpensive software options for designing 3D models, for printing or otherwise.


This is part of the free 123D suite of tools from Autodesk. You can model objects using its easy-to-learn interface, prepare your models for printing, export them to STL files, or send them directly to many popular fabrication companies. It includes a variety of popular 3D model creation, scanning, and sculpting apps, including the popular 123D Catch and 123D Design.


Recently rescued by Autodesk, Tinkercad is a web-based modeling program. With a WebGL-enabled browser such as Google Chrome or Firefox, you can run Tinkercad’s 3D user interface directly in your browser. Build up your design, save it online, and share it with others. You can also send files directly to popular 3D printing services or download STL files for printing yourself.

Fabric Basics

Becky Goldsmith C&T Publishing ePub

fabric basics


A quilt shop can seduce you with color. New fabric is likely to attract you first, but be sure to look at the other fabrics in the shop as well—you may be surprised at what you find.

When I shop, I spend more time looking at fabric that is typically “me.” However, every now and then I fall for a fabric that is outside of my normal range, which is why I look at all of the fabric in the shop.

Solids are an important addition to your stash.

Prints are exciting, but don’t forget to look at solids. You need them in your stash.

How much fabric should you buy? I buy more fat quarters than anything else. I buy half-yards of fabric that I know I’ll use—dots, some stripes, unusual prints. I buy one-yard cuts of large-scale prints, of fabric that I think I might use for an appliqué background, or for quilt backs and binding. I rarely buy more than a yard of any fabric.

Remake: Infinity Scarf Makeover

Suzannah Hamlin Stanley Stash Books ePub


Infinity Scarf Makeover

This is one of my favorite sewing projects. It’s perfect for both the beginning DIYer and the advanced sewist. While fringed scarves are a great basic by themselves, I am a fan of the more recent trend of infinity scarves that loop around without ends. This project turns an old, tired fringed scarf into a chic infinity scarf and teaches you how to make French seams, a classic sewing technique. French seams are beautiful, quality seams that hide raw edges without the need for a lining or edge stitch.

You Will Need:

•Basic woven scarf

•Standard sewing supplies

Get It Done

1. Fold the scarf in half crosswise, bringing together the fringed sections. If the scarf has a pattern or print that gives it a right and wrong side, make sure you fold together the wrong sides for this seam, which should face inside at this stage. Pin and sew a straight seam ¼˝ (6mm) from the finished edge of the scarf (ignoring the fringe).
