3D Printing News Alert(Create recycled plastics 3D printer)

Posted on Updated on

According to Create,” a community development nonprofit that invests in the arts, innovation, and creativity to improve the quality of life in Stevens Point. The organization runs an innovation center that supports creative arts, business, and community projects with work, meeting, and makerspaces, and other shared resources.

Create recently added a second 3D printer to the hockey arena center. With a few planned tweaks, this printer will be the only publicly available large-scale 3D printer in North America capable of printing directly from recycled plastics”.

Photogrammetry software for 3D Printing

Posted on Updated on

Photogrammetry software for 3D Printing. According to Sculpteo, “3D scanning could be useful for various applications. It can be used to get a viable 3D model and make the most of the 3D printing technology using an online 3D printing service such as Sculpteo. But having a great 3D design is also an amazing tool for visualization.

Photogrammetry is useful for topographic mapping, architecture, engineering, or even geology! There are a lot of software tools dedicated to aerial photos, photogrammetry is really useful for geographical use. For instance, archeologists are also using it to create plans for complex and remote sites”.

Some of the best free photogrammetry software


Agisoft PhotoScan
3DF Zephyr Free
Colmap
Visual SFM

Paid software

Context Capture
Reality Capture
3DF ZEPHYR
Autodesk ReCap Pro
Inpho
iWitnessPRO
Pix4Dmapper
Photomodeler Pro 5

According to some comments,
“It is still easier to 3D sculpt from scratch than to scan using photogrammetry in some cases. As some 3D sculpting will be needed when cleaning and patching anyway.
Zephyr offers a function where you can upload an mp4 / video file. Pretty cool feature. It does all the things in the video but in one tool. Much easier to use as well. Free is capped at 50 photos.
COLMAP is sooo cool and cheaper smarter alternatives.
Autodesk Recap is paid and limited (I heard that there is a limit number of the image you can upload to their cloud – and it’s the web-based application so if you don’t have internet, you can’t do anything).

Some people like VisualSFM and best software to do this is still pix4d. These are also powerful and free, it uses additional CSM tools you need to install for as dense reconstruction; it works great with different image sources.
3D Creator from Sony Xperia is really easy and awesome and avoid a lot of steps compared to this traditional method.
Agisoft Photoscan is far better than Colmap+ Meshlab.
For some problems, we can get suggestions from the comments.
I am trying to get into 3D computer modeling, and I want to model this new military helicopter for a video game (ARMA 3).
The problem is the chopper is extremely new and there are very few pics of it out there, so the background in each photo is always different. would these cause problems with modeling.
If you want to get some pretty amazing results using the basic version of Agisoft Photoscan ($179 US for a commercial license) and some very good results with VisualSFM (free for non-commercial use).
You can rotate the object as long as the background is in solid color. There are several solutions on the internet, mostly by programming Arduino to rotate turntable with the object, then sending remote shutter signal to the camera. This whole process can be automated with very good results:)

NASA’S 3D printed habitat challenge

Posted on Updated on

According to NASA,” The 3D-Printed Habitat Challenge will culminate with a head-to-head subscale structure print May 1-4, 2019, and the awarding of an $800,000 prize purse. Media and the public will be invited to attend the event in Peoria, Illinois.
Eleven team entries were scored and awarded points based on architectural layout, programming, efficient use of interior space, and the 3D-printing scalability and constructability of the habitat. Teams also prepared short videos providing insight into their designs as well as miniature 3D-printed models that came apart to showcase the interior design. Points were also awarded for aesthetic representation and realism. After evaluation by a panel of judges, NASA and challenge partner Bradley University of Peoria, Illinois, awarded the following teams–

SEArch+/Apis Cor – New York – $33,954.11
Zopherus – Rogers, Arkansas – $33,422.01
Mars Incubator – New Haven, Connecticut – $32,623.88.
Top Three Teams Share $100,000 Prize in Complete Virtual Construction Level of 3D-Printed Habitat Challenge”.


According to the comments they have some suggestions and worries about it, “I appreciate the focus on radiation protection for this habitat. It is often overlooked.
I like this design the most so far. I think you could add a completely sealed basement/bunker survival cell to the lower section that sits underground, just in case.
The concept is great, but the way it’s constructed would seem like it’s exposed to a lot of martian dust.
How are they going to print that over 50 days without getting it full of dust? By the end it has finished printing, the inside will be a sand castle.
Who will put pipes and knobs or controls in these structures plus how will you move the 3d printers to the red planet?
Much better to go underground, boring equipment is already tried an tested, protection from the elements and temperature regulation will be much easier and it wouldn’t need many materials to seal it off from the outside.
Brilliant design, but total fantasy. This couldn’t be built, with today’s technology, right here on Earth, with a full crew of human technicians to correct the inevitable bugs, how could this possibly work on Mars? And all the materials manufactured from Martian dirt”.

3D Printing trends and the possible future in 2019

Posted on Updated on

3D Printing trends and the possible future in 2019. We already know the little bit about 3D Printing.
We are still in the learning process. Nobody is perfect and we are also don’t know several things:)
We learn new things every day. We are so curious to explore what are the new material, products, and any new kind of printer.
Even though we buy everything, what is the importance of those things.
I think reading more books can satisfy our curiosity.

Dr. 3D Printer precautions for advanced manufacturing( Laser Cutting with a 3D Printer )

Posted on Updated on

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.

3-D printing with Cellulose

Posted on Updated on

According to John Hart and Sebastian Pattinson, a former postdoc in mechanical engineering who is now a lecturer at the University of Cambridge in the U.K., “demonstrated a technique using the world’s most abundant natural polymer-cellulose. at MIT,” says early education on 3-D printing is the key to helping the technology expand as an industry. They are very much enjoyed creating and teaching the course and they are proud of what the students did, and what it means about the future potential of additive manufacturing.
Cellulose offers many advantages over current plastics-based feedstocks: It’s inexpensive, renewable, biodegradable, mechanically robust, and chemically versatile. In addition, it’s widely used in pharmaceuticals, packaging, clothing, and a variety of other products, many of which could be customized using 3-D printing”.
