Sand 3D Printer before and now

Posted on Updated on

According to Sculpteo, “Binder Jetting printers spread a layer of the material and then bind it with an agent, which solidifies the particles. A layer for sand 3D printer is 140-200 micrometers.”
According to Markus Kayser,” he talks about ‘desert manufacturing’: a combination of solar power and 3D printing to create objects made entirely out of the sand. As a product designer, he has created a variety of beautiful objects only using the sun and sand.”
According to ExOne’s digital part materialization,” (3D printing) process for printing sand casting molds and cores, beginning with a digital file, going through solidification analysis, printing and finally casting a finished industrial part.”

also side topic, I still think bricks made from lava would be a good cheap way to get building materials, you could scoop lava into brick molds with industrial robots and also if you push a magnetic field thru the lave as it cools you could leave a build signature in the structure, that could be used in the future to date and specify where it was made sort of like a bar code but magnetic. but still, lava is still a good material that is underused.
According to AFS MCTV, “I want to see it get to the point where a 3D printer in a desert would be able to print the components for another printer.
This webinar covers the basics of additive manufacturing as well as explains the technology used to create molds and cores with a 3D printer. Led by Dave Rittmeyer and Steve Murray, both of Hoosier Pattern, the webinar will give attendees full access to two industry veterans who have worked in metal casting for a combined 50 years. Attendees will have the opportunity to ask questions, learn from industry experts and see examples of how 3D printed sand has been used within the metal casting industry.”
According to Meimad3, “World’s largest commercial 3D printer (printing volume 4x2x1 meters) – for printing Sand-Cast mold parts for the metal cast.”
According to General Foundry Service, “3d Printed Sand Molds.”
The webinar will cover the basics and explore how to utilize 3D printed sand components on your next project.

You could print big columns in low spots to serve as pilings. Then, you can cap the area with a walking machine so the structure doesn’t get buried. Over time, the additional capped ground will develop a white color which reflects the sun. You could print tunnels and bury them so they stay cool.

Is a sand 3D printer the future of Additive Manufacturing?

The emergence of “4D printing”

The emergence of “4D printing”


Imagine things can replicate by itself an appropriate design. In my opinion, we need 4D printing to make water pipes for snowing region.:)
MIT researcher Skylar Tibbits works on self-assembly — the idea that instead of building something (a chair, a skyscraper).
He is an artist and computational architect. Skylar Tibbits is working on “smart” components that can assemble themselves.
3D printing has grown in sophistication since the late 1970s; TED Fellow Skylar Tibbits is shaping the next development, which he calls 4D printing, where the fourth dimension is time.
This emerging technology will allow us to print objects that then reshape themselves or self-assemble over time.
Think a printed cube that folds before your eyes, or a printed pipe able to sense the need to expand or contract.

3D printing & medical applications


3D printing reduce the work time and it has solution and advancement for the medical field. Carsten Engel is  biomedical engineer from the University of Brussels (ULB).currently he is working as a researcher at SIRRIS (Collective Centre of the Belgian Technology Industry) which has the biggest European Additive Manufacturing machine parc. His main work involves R&D projects in the field of biomedical and aerospace applications.

Polymer based 3d printing from Carbon3D

Polymer-based 3d printing from Carbon3D


Carbon3D has announced a new approach to polymer-based 3D printing.  Their approach is based on CLIP (Continuous Liquid Interface Production) technology which continuously grows objects from resin instead of the conventional approach of the layer by layer printing.  Joseph DeSimone, co-founder of Carbon3D and Chancellor’s Eminent Professor of Chemistry, UNC, mentioned in his Ted talk in Canada, that this technique was inspired by the film Terminator 2, in which the T-1000 robot rises from a pool of metallic liquid.  According to DeSimone, objects created by conventional 3D printing are weak because they are made up of multiple layers obtained by 2D printing over and over again.  In contrast, CLIP based 3D printing is 25-100 times faster and generates much stronger objects.:)
