标题: 3D打印的手环设计
软件：solidworks,当然你可以使用任何3D设计软件

3D打印成型技术：SLS

3D打印的材料：尼龙你也可以使用其他高分子复合材料或者用PLA也行

看看上图的打印效果，是不是很炫。手链+手镯

好了接下来一步一步告诉你怎么实现的。

设计师： Gordon Lardi

Step One: Design a single bracelet link.

Lardi has used a capsule shape for the individual beads in order to give the bracelet some weight and depth. From the first step in the tutorial you will notice the need for parametric modeling software (SolidWorks or Fusion360). These tools allow you to easily go back and edit dimensions where needed without having to redesign the entire bead or bracelet.

Step 2: Twist single link.

Flex the entire body of the bracelet link to give the bracelet the rope twisting appearance. When twisting the bead in this way, you may reveal sharp edges. At this step you will want to fillet or round off those sharp edges.

Step 3: Create chain of links.

Now that the bead is complete, create a linear pattern of the links to create a single bracelet. Set the number of links appropriate to your desired bracelet or chain size.

Step 4: Check how your links fit.

Inspect the chain by temporarily splitting the design in half. You want to make sure that your links are not touching or are too close to the connecting link. This will ensure that while your chain is printing, the links do not fuse together. Lardi recommends that you at least provide 0.5mm – 1mm of clearance.

Step 5: Create Fastener

The final step in creating the rope bracelet is designing the hook or fastener. Lardi was looking to create an “uninterrupted rope appearance,” so he developed a final link that would blend in with all of the other links. Lardi designed a snap on hook by trimming the opening slightly larger than the width of the link. This would allow the hook to easily snap on and off.

Once the initial design was complete, Lardi ordered a prototype of the design in black Strong & Flexible nylon. Using the iterative design process, Lardi ordered the design three times with slight dimensional changes in between to get the design and fit just right.
