Just because things are 3D printed does not mean they are better.

Just saying, other manufacturers may have tested this idea before. I mean a 3d printed caliper can have lighter weight and better thermal control which is obvious enough for researches to be done. But still, good marketing peace of work. Hope this amazing technology can be used on consumer cars.

How hot was the calliper getting and how much was it deflecting? Mechanical properties are reduced at high temperatures, it’s impressive that it survived the test but I would like to know if it yielded or not and how many high load/temperature cycles it is capable of. It should be ok being Ti.

3d printed car parts are probably normal in the future, imagine if your car breaks down and you have it brought to a mechanic. Today that mechanic has to order the parts which will take atleast multiple days, with 3d printed parts it is a matter of hours,

3D-printed bathroom

Posted on Updated on

NTU Singapore develops technology that can 3D-print a bathroom unit within a day
According to Assoc Prof Tan Ming Jen,” 3D-printing a bathroom unit could help manufacturers halve their production time while lowering transport costs, carbon emissions, and materials wastage. Less space is required to create and store the same number of PBUs in land-scarce Singapore since conventional PBUs take about two weeks before they can be ready.

By being able to print-on-demand, companies can save on their inventory costs as well as manpower costs, as they don’t have to hold as much stock and their workers can be redeployed to do higher-level tasks. This approach improves the safety of the workplace since robots are doing the construction of the bathroom unit.

According to team lead from Sembcorp Design and Construction, and Sembcorp Architects & Engineers Er Lie Liong Tjen, “3D printing technology allows concrete to be printed and customized. The complicated shape of a PBU and its walls can be developed and printed at a faster pace to satisfy the needs of individual customers as no formwork or molds are required, whereas conventional construction of PBUs with concrete or lightweight wall panels always limit the possibilities of design. In addition, 3D printing can build curvilinear profiles rather than rectilinear forms”.

Air NZ uses a 3D printer for speedy

Posted on Updated on

Air NZ uses a 3D printer for speedy. According to Air New Zealand,” has teamed up with components and systems provider Moog, Microsoft and ST Engineering on a world-first experiment which has the potential to transform aerospace supply chains by leveraging 3D printing and Moog’s blockchain enabled VeriPart™ process to create a point of use, time of need a digital supply chain.

The proof of concept has seen Air New Zealand order a digital aircraft part file from Singapore-based ST Engineering. The digital file was immediately sent to an approved printer, operated by Moog in Los Angeles, downloaded and 3D printed before being installed within hours on an Air New Zealand Boeing 777-300 aircraft ahead of its scheduled departure”.

Master chef fans lose it ‘3D printer’ dessert food printers

Posted on Updated on

Master chef fans lose it ‘3D printer’ dessert🥧 food printers combine nozzles, powdery material, lasers and robotic arms to make sculptures and geometric shapes.
According to Master Chef judge Matt Preston, “the dish had a “cutting edge-type element” on it before they saw it.

We’ve seen the dish🍳. There’s one element there that I don’t think I’ve seen on an Australian restaurant menu anywhere else around the country. And that’s a totally cutting edge-type element that I think is going to bake your noodles🍝,”.

3D, 4D 5D Printing Vocabulary

Posted on Updated on

3D Printing—-

Through computer programmed deposition of material in successive layers to create a three-dimensional object. 

4D printing—–

4D printing adds the dimension of transformation over time.

5D Printing—–

Stereolithography for 3D printing —-

stereolithography apparatus, optical fabrication, photo-solidification, or resin printing) is a form of  3D printing technology used for creating models, prototypes, patterns and production parts in a layer by layer fashion using photopolymerization, a process by which light causes chains of molecules to link, forming polymers.

Stereolithography for 4D printing——

4D printing is fundamentally based in stereolithography, where in most cases ultraviolet light is used to cure the layered materials after the printing process has completed.

Fiber Architecture—-

 Most 4D printing systems utilize a network of fibers that vary in size and material properties. 4D printed components can be designed on the macro scale as well as the micro scale.

Hydro-reactive Polymers/Hydrogels for 4D printing—–

Skylar Tibbits is the director of the Self-Assembly Lab at MIT and worked with the Stratasys Materials Group to produce a composite polymer composed of highly hydrophilic elements and non-active, rigid elements. The unique properties of these two disparate elements allowed up to 150% swelling of certain parts of the printed chain in water, while the rigid elements set structure and angle constraints for the transformed chain. Tibbits et al. produced a chain that would spell “MIT” when submerged in water and another chain that would morph into a wireframe cube when subjected to the same conditions.

Cellulose Composites for 3D printing-———-

Cellulose-based material that could be responsive to humidity.  Wood composite materials that change shape based on their printed grain direction and anisotropic swelling when water is absorbed. This work is 3D printed and studied on the macro scale rather than micro scale, with layer heights at fractions of millimetres rather than microns. 

Thermo-reactive Polymers/Hydrogels for 4D printing—–

Thermo-responsive material.  This new type of 4D printed hydrogel is more mechanically robust than other thermally actuating hydrogels and shows potential in applications such as self-assembling structures, medical technology, soft robotics, and sensor technology. A fluid controlling smart valve printed from this material was designed to close when touching hot water and open when touching cold water. 

Digital Shape-Memory Polymers for 3D printing-———

SMPs are able to recover their original shape from a deformed shape under certain circumstances, such as when exposed to a temperature for a period of time. Depending on the polymer, there may be a variety of configurations that the material may take in a number of temperature conditions. Digital SMPs utilize 3D printing technology to precisely engineer the placement, geometry, and mixing and curing ratios of SMPs with differing properties, such as glass transition or crystal-melt transition temperatures.

Stress Relaxation for 4D printing———-

4D printing is a process in which a material assembly is created under stress that becomes “stored” within the material. This stress can later be released, causing an overall material shape change.

Thermal Photo-reactive Polymers for 4D printing-——–

This type of polymeric actuation can be described as photo-induced stress relaxation.

3D Modeling-——-

CAD, 3D scanner

3D printing-——

Before printing a 3D printing model from an STL file, it must be examined for an error. Most CAD applications produce errors in output STL files.

STL files-

Repair fixes in the original model.

3D scanner——

A 3D scanner is a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance

G-code

G-code is a language in which people tell computerized machine tools how to make something. The “how” is defined by g-code instructions provided to a machine controller (industrial computer) that tells the motors where to move, how fast to move, and what path to follow.

Laser printing—–

Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a “drum” to define a differentially charged image. The drum then selectively collects electrically charged powdered ink toner, and transfers the image to paper, which is then heated in order to permanently fuse the text and/or imagery. As with digital photocopiers, laser printers employ a xerographic printing process.

Injection moulding

Injection moulding Bre or Injection moulding Ame is a manufacturing process for producing parts by injecting material into a mould. Injection moulding can be performed with a host of materials mainly including metals, glasses, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cools and hardens to the configuration of the cavity

How to 3D printed Copy Any Object

Posted on Updated on

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.”:)

3D Printing with PETG

Posted on Updated on

According to the comments,”PETG for strength and durability,  polyethylene terephthalate (think plastic bottles) and the G means it’s been glycol modified for extra durability. PLA for speed and a little extra quality. It’s good stuff. PEI is an ideal print surface for PETG it adheres well but doesn’t fuse like it does to glass. The advantage of PETG is minimal warping, so you don’t need a heated chamber and virtually no smell with PETG”.:)
