Forces impacting on the 3D printer frame

Frame design priorities: Convenient adjustment of XY and Z portals Redesign of 3D printer HYPERCUBE. Will fit into an extruded profile length of 6 meters. (Stores providing sales and cutting services sell it in multiples of 6 meters, sometimes in multiples of 3 meters.) I have not seen detailed articles on the Internet about what forces impact on the frame of a 3D printer. So I decided to write about it. I plan to print infill at 150mm/s First, let’s determine what forces and where impact on the frame at a given speed. Let's imagine that the printer is running at a speed of 150 mm/s and the print head suddenly stops. Let's break it down into several tasks. What is the displacement of the frame during heavy braking along the -X and +X axis? What is the displacement of the frame during sudden braking along the -Y and +Y axis? What is the displacement of the bed console during heavy braking in the X and Y axes? We determine the forces impacting during sudden braking for the X and

Proportions and scale in cosplay

I've decided to share a small guide on how to make your cosplay look harmonious and beautiful. I often get asked, "Can you craft it?" but when it comes to the question of "What are the dimensions?" people often struggle or provide very disproportionate measurements. The first thing you need to do is find a good reference image. Ideally, we need two types: a front view and a side view. Let's take the character Nobara Kugisaki from Jujutsu Kaisen as an example. She has a hammer. We'll calculate its dimensions based on the desired height. Alright, it seems like we've found one, but in this image, we can only see the details of the hammer, and determining its dimensions will be quite problematic. Let's continue searching. But make sure to save this image! Here's what we need: the lady is standing at full height, arms approximately at the seams, and the hammer is almost in profile, slightly turned – but that's not critical. Next, we'll inp

Mates for non-circular fasteners in Solidworks

In SolidWorks, inserting cylindrical hardware is straightforward, but the process for hexagonal or square hardware may not be as intuitive. For instance, adding a Hexagon Rivet Nut or a bolt with a square neck into your design might seem less clear-cut. Below are instructions applicable to any non-round hardware, illustrated through several examples. Example 1: Inserting a hex rivet nut into a hex hole. Insert the metalware into the assembly. Select the face and the edge, then click on the mate Profile Center and confirm with the green checkmark. If the nut appears sideways, don’t worry. Simply click on the arrow to orient it correctly. Done! This method works for various types of non-round fasteners. Example 2: Square neck bolt and rectangular hole. Select the edge on the bolt and the edge on the slot. –°lick on the mate Profile Center and confirm with the green checkmark. Perfect! Fix the orientation of the bolt mating in the slot if it's incorrect. However, there are instances w
