User:AndrewPpohl/3D printing

This article is generally very well put together. Sources are almost always used on each individual claim made and things are almost always written from a neutral and factual perspective. There's just a couple sections that could use some help though I think.

General Principles


 * 4D printing is a bit of a separate topic, this could likely just be given its own mini article for itself
 * The section on finishing is a bit long and some parts seem unnecessary. Most people coming to Wikipedia to research 3D printing likely aren't going to be going there to research methods for painting 3D prints, much of the topic seems unfocused and could use work.

Applications


 * Since 3D printing is such a widespread technology that affects so many industries this section could have several sub articles of its own, and the section in the main article could be shortened. As it stands some of the topics discussed aren't in depth enough to truly give an idea of how it affects each industry, but is also too long to really fit onto a more general wiki article like this one

Edit Suggestions


 * In the history section for the early 2000s the section is extremely short even though this was a pivotal time for the technology, as this is when it came into the hands of the average consumer. Consider a change like this:
 * In the 2000s users began to design and distribute plans for 3D printers that could print around 70% of their own parts, the original plans of which were designed by Adrian Bowyer at the University of Bath in 2004, with the name of the project being RepRap (Replicating Rapid-prototyper).
 * Similarly, in 2006 the Fab@Home project was started by Evan Malone and Hod Lipson, another project whose purpose was to design a low-cost and open source fabrication system that users could develop on their own and post feedback on.
 * Much of the software for 3D printing available to the public at the time was open source, and as such was quickly distributed and improved upon by many individual users. Projects like RepRap and Fab@Home played a large parts in making 3D printing more broadly accessible, as prior, the technology was largely used for mostly industrial purposes. In 2009 the Fused Deposition Modeling (FDM) printing process patents expired. This opened the door for these communities to begin a new wave of  startup companies, with the goal of many being to start developing commercial FDM 3D printers that  were more accessible to the general public.
 * The Circuit Boards section under applications needs to be moved to the sub article and heavily cut down on the main article, this applies to basically the entire application section, but the sections about circuit boards, the medical sector, and the automotive industry definitely need this. The automotive industry section could be more in depth and the medical sector and circuit board sections need to be moved and cut down. The medical equipment section also seems unnecessary since we already have a section for the health sector that we can put this in.
 * In general I wanna focus on the applications section, this section is incredibly long and needs to be shortened since there's an entire sub article on this topic that readers can go to if they want more detailed explanations
 * I want to move the quote under the fashion section since it's mostly a speculative piece and would be better off moved to the sub article, people are on this Wikipedia article for a general explanation and concept, they aren't here for speculation
 * Vanessa Friedman, fashion director and chief fashion critic at The New York Times, says 3D printing will have a significant value for fashion companies down the road, especially if it transforms into a print-it-yourself tool for shoppers. "There's real sense that this is not going to happen anytime soon," she says, "but it will happen, and it will create dramatic change in how we think both about intellectual property and how things are in the supply chain". She adds: "Certainly some of the fabrications that brands can use will be dramatically changed by technology."
 * In the firearms section the term AM is used to describe additive manufacturing, don't do this, it saves space sure, but the average reader isn't going to know what this means as easily

The application of 3D printing for the representation of architectural assets has many challenges. In 2018, the structure of Iran National Bank was traditionally surveyed and modeled in computer graphics software (specifically, Cinema4D) and was optimized for 3D printing. The team tested the technique for the construction of the part and it was successful. After testing the procedure, the modellers reconstructed the structure in Cinema4D and exported the front part of the model to Netfabb. The entrance of the building was chosen due to the 3D printing limitations and the budget of the project for producing the maquette. 3D printing was only one of the capabilities enabled by the produced 3D model of the bank, but due to the project's limited scope, the team did not continue modelling for the virtual representation or other applications. In 2021, Parsinejad et al. comprehensively compared the hand surveying method for 3D reconstruction ready for 3D printing with digital recording (adoption of photogrammetry method).

Discussion here about things like Cinema4D and Netfabb really aren't important, the average reader won't be thinking about this.

Get rid of this line: "3D printing was only one of the capabilities enabled by the produced 3D model of the bank, but due to the project's limited scope, the team did not continue modelling for the virtual representation or other applications". Completely unnecessary to the topic at hand.

This line could also be expanded on and moved the sub article, as it stands this also has nothing to do with the topic at hand: "In 2021, Parsinejad et al. comprehensively compared the hand surveying method for 3D reconstruction ready for 3D printing with digital recording (adoption of photogrammetry method). ".

In the 2000s users began to design and distribute plans for 3D printers that could print around 70% of their own parts, the original plans of which were designed by Adrian Bowyer at the University of Bath in 2004, with the name of the project being RepRap (Replicating Rapid-prototyper).

Similarly, in 2006 the Fab@Home project was started by Evan Malone and Hod Lipson, another project whose purpose was to design a low-cost and open source fabrication system that users could develop on their own and post feedback on.

Much of the software for 3D printing available to the public at the time was open source, and as such was quickly distributed and improved upon by many individual users. Projects like RepRap and Fab@Home played a large parts in making 3D printing more broadly accessible, as prior, the technology was largely used for mostly industrial purposes.

In the early 2000s 3D printers were still largely being used just in the manufacturing and research industries, as the technology was still relatively young and was too expensive for most consumers to be able to get their hands on. The 2000s was when larger scale use of the technology began being seen in industry, most often in the architecture and medical industries, though it was typically used for low accuracy modeling and testing, rather than the production of common manufactured goods or heavy prototyping.

In the 2005 users began to design and distribute plans for 3D printers that could print around 70% of their own parts, the original plans of which were designed by Adrian Bowyer at the University of Bath in 2004, with the name of the project being RepRap (Replicating Rapid-prototyper).

Similarly, in 2006 the Fab@Home project was started by Evan Malone and Hod Lipson, another project whose purpose was to design a low-cost and open source fabrication system that users could develop on their own and post feedback on, making the project very collaborative.

Much of the software for 3D printing available to the public at the time was open source, and as such was quickly distributed and improved upon by many individual users. In 2009 the Fused Deposition Modeling (FDM) printing process patents expired. This opened the door to a new wave of startup companies, many of which were established by major contributors of these open source initiatives, with the goal of many of them being to start developing commercial FDM 3D printers that  were more accessible to the general public.

The whole section about soft actuators also seems unimportant and can be moved to the sub article, it's too specific of a topic, the applications section should probably focus mostly on broader topics than this, things the average Joe is going to understand why it's important.
