FDM: 10X Faster. Thinking (And Moving) Ahead.

10xfasterprinting
We can continue to move FDM printing ahead in many ways. You just need to think differently, and don't take no for an answer. A few industry figures have said "FDM is near its limits for wher ethe tech can go." I have never took that as policy and neither should you. Awhile back, two MIT professors, Jamison Go, and John Hart have  developed  a new 3D printing hardware called  FastFFF (Fast Fused Filament Fabrication)  which is ten times faster than 3D printers we use today. Research papers and more information can be read here: Science Direct Heres the abstract: "Significant improvements to the  throughput  of  additive manufacturing  (AM) processes are essential to their cost-effectiveness and competitiveness with traditional processing routes. Moreover, high-throughput AM processes, in combination with the geometric versatility of AM, will enable entirely new workflows for  product design  and  customization . We present the design and validation of...

The First Layer. Elusive? No. Common Sense.

first_layer_example2
The importance of the first layer is paramount and will usually determine if your model is going to fail later in the build or not. Credit: Peter Solomon   Too many people do not give enough attention to all of the details to get the right first layer. Once that you do, so many of your problems will disappear and your printing will become fun and much more predictable! There are 6 Main Factors in getting the perfect first layer 1. Well Trammed Machine (this is not so much about the first layer as in good preparation for the rest of your steps) Tramming your machine is making sure all of the components are at perfect 90° to each other, this doesn't mean leveling with a bubble level gauge. It means making sure your vertical elements are all at 90° to the horizontal elements, that your X gantry is Parallel...

Wanhao Duplicator D9 Bed Leveling Modification: The Next Level.

D9_Bed_Mod_01c
I decided to make an improvement to the Buildplate and Y Carriage on our machines here after coming to the conclusion that the recent updates to the D9's firmware and auto-leveling feature should now be able to make use of the changes I've made. Once you reset your Z, auto leveling will be easier since you are now basically giving it a level bed to start with and can rely on the software. The tension spring system is now, legacy and outdated in my opinion.     Some background on it; I have been using printers with similar features for years now. I've never been a fan of constant, and eventual (still) periodic adjustment to bed leveling for that sought after first layer goodness, not when we have already had the means to do away with that system altogether. I'm used to having my printers tuned to set it and forget it....
