This isn't going to be a long post - just a quick reminder that cooling is often a critical part of controlling warp and other problems when 3D printing PLA or many other materials.
Even a well calibrated printer/slicing profile can give you problems with curl, especially on outward sloping convex surfaces (like the underside of the bow on a Benchy print). Material selection, ambient (room) temperature, print speed, layer height, nozzle temp, and other print settings are all contributing factors, and will hopefully be a subject of a future post.
These two prints were done with the same material, on the same printer, with the same gcode file, at similar room temperature. The only difference between the prints was whether or not there was active cooling on the print.
It's a pretty stark difference. The nasty finish on the underside of the bow are caused by the material curling upwards on each layer and interfering with the subsequent layers, displacing the material and pushing it outwards erratically, causing bumps, pits, and general roughness.
Now here's the kicker - the cooling method... This was printed on a Monoprice Dual which doesn't have any form of active cooling. For lack of time to put something better together, here's the fan configuration we slapped together.
This is a cheap little desk fan that came from Walmart a while back, taped to the top of the printer with gaffer's tape (the best tape). It's clumsy, chincy, crude, and ugly, but it does the job 80% of the time.
While you're almost certain to get better results from something directed more closely at the print, particularly the end of the nozzle and that vicinity, sometimes the hack will do, especially in a pinch if you REALLY need a print to work without working on your printer.
I received some sealing wax for Christmas to use with a signet ring and thought it would be a cool project to design and print some stamps to use with the wax. The approach to adding graphics to an OpenSCAD design seemed worth sharing as well. Here's the first 3D Printed stamp I made. It is [...]
3D Printing is excellent for supporting all kinds of hobbies and art forms. Check out some of the tools and accessories we came up with for working with rocks and gems!Rock Slab Display Stand Slabs of beautiful stone are often displayed on stands commonly made from cut and bent acrylic sheet, or occasionally from bent metal [...]
In rearranging things in the yard, we had these old solar path lights that needed to be moved, and which were due for some refurbishment. We pulled eight of them and discovered that four were without the stake at the bottom. I decided to design and print some new stakes for the lights before redeploying [...]
Succulent plants are gaining popularity because of their low maintenance care and multitude of planting options. Cuttings from succulents can be replanted to produce even more plants. The tiny geometric succulent holders we printed are perfect for holding succulents and the design can be adjusted depending on the size and growth of your plant. Check [...]
iPhones have created a wealth of opportunities for you to customize your own accessories. Most notably, cases for iphones are of importance because they provide protection and customization for the product. Because Apple often changes the dimensions of their phones, you can print cases, stands and other accessories to keep up with the changing dimensions [...]
Some time ago we were helping out the Biology Department at Walla Walla University get a printer dialed in for some work they wanted to do. In our work with them, they gave us these images they took with the help of Whitman College, using their scanning electron microscope and gave us permission to publish. It's been a [...]
This is a library file I put together to make routine tasks easier in OpenSCAD. Features include some often-used constants, divisions of 360 degrees into different numbers of sections, chain hull, hex rod, and some features for working with 80/20 10-Series T-Slot. I'll provide some explanations and examples below to demonstrate how I use some [...]
