Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

3D Printing and the Circular Economy Part 7: the Viability of 3D Printing

Circular Economy Cycle

It is important to address that waste is less of an issue when a mindset is adopted towards solving it. I make this disclaimer because as we have been looking into this series on the circular economy, we have initially outlined various ideals and thought processes opposed to focusing solely on 3D printing. Any mindset shift towards a more circular economy is necessary before we can utilize a technology to build towards this ideal. 

3D printing is a great technology due to its ability to be an additive process versus a typical subtractive process that is found in most manufacturing environments. In this article, we will discuss a bit more on the implications of additive technology and other initiatives associated with it. This will help us to have a larger view of the circular economy as well in relation to additive manufacturing. 

Additive technology is amazing in terms of waste reduction overall. When a technical system is built to create product based on building up, there is a larger ability for sustainable development as people print items as they need them. With a subtractive manufacturing process, products are created by taking away from larger materials. This can leave many pieces unusable after the initial product creation. This then leaves a product residue to either be thrown away or in need of further recycling. This then takes a lot of time to conduct, and it becomes an issue of efficiency within the circular economy framework. Not only does this process waste time, but one must now calculate other factors such as transporting residual waste and how much energy that consumes. There are a lot of factors that do not have deeper analysis in terms of the classical manufacturing process.

3D Printing Waste

The additive manufacturing field is ripe for experimentation as it is a naturally disruptive concept and methodology. A very important thought process within the field currently is a focus on material development. Material development is essential when it comes to sustainability. Depending on polymer structures, we can build various materials that have specific properties that are of our liking. This can lead to materials that are also easier to recycle, as well as they have natural biodegradable properties. It is still important to build out a larger infrastructure of life that would lead to people actually being knowledgeable of their choices and how they affect the greater world. Although 3D printing inherently helps to prevent excess production, it is still a problem of lack of awareness for people in terms of their production and consumption rates. There are a large number of people making prototypes that fail in terms of print standards. This then leads to larger amounts of waste as well.

Material Development

In terms of sustainability, additive manufacturing is better than traditional methods. It is still imperative to realize that we are at a loss in terms of sustainability if we are not working on infrastructures. This includes infrastructures of thinking as well as infrastructures of methodology. We must utilize technology such as 3D printing to benefit the world. We should not abuse the benefits that this technology can provide to the larger scale of humanity.

What is Metrology Part 2: CMM

CMM

A CMM is a widely used machine used to measure objects. A CMM is a coordinate measuring machine. This refers to any machine that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. This is the essence of many a metrology system. The precision of a CMM is vital for determining the geometry of objects. This then leads to more precision in the manufacturing and replication of objects. 

Probes are the engine of a CMM. They sense objects through their surfaces. There are various types of probes as well.  The types of probes used in CMMs include mechanical, optical, laser, and white light. Mechanical probes typically have a ball and rod looking setup attached to them, or have a nozzle setup. These physically touch the surface of a material that is in need of measuring. Optical probes typically refer to spectral analysis and measuring through these means. One can think of a fiber optic probe in particular. These type of probes are usually used in Raman spectroscopy, and diffuse reflection applications. Raman spectroscopy is a spectroscopic technique based on inelastic scattering of monochromatic light, usually from a laser source. Inelastic scattering means that the frequency of photons in monochromatic light changes upon interaction with a sample. The scattering of the photons within a monochromatic light source allows for a device to detect if an object is within the path of monochromatic light. This thus leads to measuring capabilities that are important in terms of a CMM as well. Diffuse reflection is similar to Raman Spectroscopy aside from the optical source is typically infrared. When an IR beam passes through a physical object, it can be reflected off the surface of a particle or be transmitted through a particle. The IR energy reflecting off the surface is typically lost. This transmission‐reflectance event can occur many times in the object, which increases the pathlength. This pathlength is vital for measuring. Finally, the scattered IR energy is collected by a spherical mirror that is focused onto the detector. The detected IR light is partially absorbed by particles of the object, collating the object information.

Typical Raman Spectroscopy Setup

A CMM is heavily reliant on a built-in coordinate system of, typically, three axes. This is similar to the coordinate systems we are aware of within a 3D build environment. This is a Cartesian Coordinate system. The main structure of which includes three axes of motion. The material used to construct the moving frame has varied over the years. Granite and steel were used in the early CMM ‘s. Today the major CMM manufacturers tend to build frames from aluminium alloy or some derivative and also use ceramic to increase the stiffness of the Z axis for scanning applications. CMM axises need to be stiff because there should be minimal outside inference with forces that may misalign the device during measurement. Any misalignment will cause higher error ranges for measurement.

Cartesian Coordinate System

Scanning techniques are becoming more reliant on data collection and compilation. These methods use either laser beams or white light that are projected against the surface of a part. Thousands of points can then be taken and used not only to check size and position but also to create a 3D image of the part also. This “point-cloud data” can then be transferred to CAD software to create a working 3D model of the part. The ability to hold various point cloud data from these methods is essential for the future development of the field. Big data is something of interest most definitely for this field. 

CMM’s are very interesting and are the basis of most metrology methods. It is important to understand how in-depth and fascinating this field is. It is a very vital one as well for the future in terms of 3D printing and manufacturing. Stay tuned for the next installment where we take a look into different subfields within Metrology as well.
