This is an older article I came upon while combing the internet for cool information on 3D printing. It came from a makerspace blog located in Southampton, UK. A nice short tutorial on designing a new holster for a modified airsoft gun.
Starts with a little intro on what the model looked like in Autodesk123D all of the way to the finished product. A very short and sweet insight of the design process. If you enjoy, please leave a comment or click on one of the share icons.
On Saturday 7th August, SoMakeIt Member Lee came to the space with an interesting challenge. He had purchased a torch attachment for an Airsoft gun which he was using for a costuming project, but the large barrel of the torch meant that the gun no longer fitted in the supplied holster. So of course we decided that using 3D printing we could quickly make a replacement that fitted perfectly.
All of you 3D printers and makers, we all have heard of resolution in the Z direction, aka layer size. The layer height determines the smoothness of the 3d printed model. The smaller the layer the smoother the model, the higher the resolution and so on.
But what about the X and Y axis of 3D printers? Something hardly mentioned in most articles about 3D printing. Does the resolution of the X and Y axis really matter?
According to the folks at Fabbaloo the answer is sometimes it does.
” I believe it is, but not for extrusion machines. Instead, it’s important for comparing resin-based 3D printers using photo curable processes.
In these machines, UV (or other) light illuminates a liquid resin surface to solidify a layer. There are generally two approaches to doing so. One approach involves a laser rapidly moving to laboriously trace the layer’s solid portions. The other typical approach is to use a DLP light source to simultaneously illuminate an array of “pixels” on the resin surface.
And this is where X-Y resolution becomes important. Why? Because DLP light sources have a fixed pixel count. The array of light pixels might be 640 x 480, or 1920 x 1080, for example.
Imagine if you shone the 640 x 480 array on a resin surface 100mm wide. Now shine the same pixels on a resin surface only 50mm wide. Are the solidified pixels the same size? No! They are smaller when focused on the smaller surface area.
Similarly, the pixels are larger when focused on a larger surface area.
In this case, X-Y resolution becomes quite important. Essentially it refers to the effective size of the solidified pixels. “
They go on to state that if you are printing something that is finely detailed such as jewelry you probably require a higher x-y resolution. In this case, you would not want to consider a resin printer that has a large surface area unless there are options for it to focus the pixel array on a smaller surface area of which, in fact, some resin printers do.
Looking for DIY 3D printed drone project? After a little research I came across a very slick looking project on thingiverse. This one is inspired by the DJI Inspire. The DJI Inspire is a very popular yet a bit on the pricey for a drone and fpb camera combo.
According to a review by CNET, CNet editor rating gave 4 out of 5 stars, stating “THE BOTTOM LINEThe DJI Inspire 1 offers an excellent aerial photo and video solution for professionals or well-heeled enthusiasts looking for a simple, ready-to-fly drone with camera-swapping potential.”
Thanks to thingiverse user CdRsKuL (located in the UK), he/she has chosen to share his quadcopter drone CAD files and electronic plans with the rest of the world. It appears they did their original 3d printed drone on a Davinci 3D printer. So if you have access to a 3D printer it should be much easier than starting from scratch.
You will need the motors, electronics, etc… but you can find the models and links to the electronic plans on CdRsKul’s thingiverse project page.
If you are truly inspired to take this project on, don’t forget to share pics with the rest of the Thingiverse world and make a donation to CdRsKul if you can afford to do so.
