I am using useful comments for this youtube video:)
Please use some precautions if you are using Laser Cutting with a 3D Printer” It is very very important to use the carbon monoxide detector.part cooling fan” style fan it will help you when you cut. It reduces the risk of something catching fire and blows away the burned wood so the laser can reach the uncut wood.
It might risk sooth accumulating on the lens and eventually blocking enough light that you damage the lens itself with the heat.
You need ventilation and more than just an open window. If you want to use the airbrush compressor into a vacuum pump to pull away from the smoke. I will be worried that you can see the laser beam through the safety-glasses.
If you want to prevent the face from getting charred, put painter’s tape on top.
If you want the laser performance to last you need another mini fan to blow out the smoke so the residue of that smoke won’t be impaired on the laser beam output if you don’t blow air in the output focus lens that lens Will get covered with the smoke residue and destroy it so you need to blow air on the output lens and evacuate the smoke at the same time, you can add a mechanical end stop to the laser to home the Z, as the laser never needs to be hitting the bed or print like a nozzle,
To prevent the scorching just add some masking tape on top of the plywood. Did you think about designing an enclosure for the hypercube? That would be the best for ventilation of all those nasty laser fumes”.
Suggestions for height adjustment–
+1 on adjusting the z height with each pass to keep the focal length the same and +1 on some air assist as the smoke will reduce the laser’s power. With both mods, you’d cut through in fewer passes.
How to 3D print copy any object. According to Switch & Lever,” Copying physical items is not as easy as copying a piece of paper, you can’t exactly stick it into a copy machine. However, surprisingly technology for how to copy physical objects have come a long way in recent years, and have also become available for those without deep pockets. In this video we’re copying a couple of different objects, using different methods, with different rates of success.”:)
According to Ron Place, he is our Dr for Dr. 3D Printer (3D printers Server Octoprint vs Repetier comparison),” This is the video showing a comparison between Octoprint and Repetier Server. They are both great alternatives”.:)
According to Angus,” He is from Maker’s Muse. He is the Dr. 3D printer for our research category. Whenever I 3D print any object it always gets stuck over the surface and breaks the object.
It is a good idea to use removable magnetic 3D printing surface. I am using the comments for my post or using cotton fabric as a 3d printed surface for the very inexpensive way. In the USA it’s possible to purchase magnetic vent covers in hardware stores like Home Depot or OSH or building stores. They are designed to cover the heating or cooling vents in your house. They’re just large flexible sheets of magnetic material.
In Australia, you can buy from the A4 sized magnetic sheet from Officeworks for $5.
you can also get self-adhesive neodymium sheets with a much stronger pull but are good to 100 degrees. There are also higher temp but lower pull sheets, but usually flexible sheets they tend to use a grade of vinyl that starts to deform around 125 degrees or so. Also, Spring temper carbon steel is often sold as hardened shim stock sheets, which you can get a little cheaper occasionally and are usually toleranced well for thickness (if it is flat… sometimes it is cut off a roll and a little bowed). If you can find a hardened piece of 1095 steel that happens to be flat, that’ll work too. “sample sheet” packs which are often 4”-6” square and are only a few bucks.
some users use the buildtak removable heat bed and the sprint steel is really high-quality stuff.
Some people use I use a sheet of 6mm acrylic held down with clips.
Some other viewers are using the sheet of 300 x 300 spring steel for about 16 GBP, around 30 AUD for you, you have to order it and it is laser cut for whatever size you want, China will be next LOL, RobUK”.:)
According to Machine Design article,”
Well-designed 3D-printed parts. Try to use honeycombs and complex matrices.3D printing suitable for end-use parts, but many parts will transition from printing to machining, molding, or casting as production volumes grow.
3D printed parts minimize post-production steps that add cost and time.
Tooling is not needed with 3D printing”.
The OpenRC F1 car is a radio control car you can 3D print and assemble yourself. You make the parts, glue them together, and then add your RC gear. That’s all well and good, but could it be done… bigger? [3D Printing Nerd] decided to tackle this one at 4x scale. It goes without saying that this took some work. The model has to be carved up into sections that would actually fit on the printers to hand. This can take some planning to ensure the parts still come out nicely, as they may be printed in different orientations or …read more
The future of 3D Print fashion and imagination.
“We are in an extremely individualistic age of fashion,” explains Michelle Finamore, curator of Fashion Arts at Boston’s Museum of Fine Arts and co-curator of the current exhibit.
