The world's first community of 3D printed homes

What were the circumstances for the community and families this project impacted?

These families were some of the lowest income, highest-need families we have ever served. At the outset of the project, we partnered with local government officials to survey more than 500 families in the area, to identify those with the greatest need. The 10 families in this community have an average median income of $76.50 per month, which is well below the lowest threshold we typically require of families we serve in Mexico. Families in this community work in a variety of occupations, and work often changes based on what is available in each season. Additionally, most of the homes the families previously lived in were prone to flooding because of their proximity to the nearby river, which overflows during the rainy season.

How did you select the families?

Families were selected using a three-part process:
1. We worked closely with nonprofit partners to identify an area with the greatest need.
2. Once an area was identified, we worked with partners to survey each family individually to understand their specific circumstances.
3. After surveying, we selected the families who have the greatest physical and financial need for a home.

When do families move-in?

The families moved in November 2021.

Did the families receive the homes for free?

Families received the homes at a zero interest, zero profit mortgage. The total mortgage amount is around 400 pesos a month, a manageable amount even for very low-income families, and lasts for seven years. The rest of the cost of the home is considered a subsidy from New Story. The mortgage funds don’t return to New Story or ECHALE, but rather are pooled into a community investment fund where families over time vote on how the funds are used.

By investing into their homes, families are more likely to stay in the homes long-term, take better care of the community, and provide more meaningful feedback through the planning process.

Did this project take jobs from locals?

Build out on the homes still required for land clearing, foundations, doors, windows, and roofs. We hired locals for all of the build out and didn’t decrease the numbers of individuals hired as compared to traditional construction.

What type of maintenance will the houses require? What is the estimated cost of maintenance and is this covered by the families or New Story?

Homes will require the same maintenance as traditional CMY block homes. New Story monitors home and community aging through our Impact Data Program. Families are surveyed before home intervention and again at various milestones following move-in. This allows us to identify any community issues that need to be addressed by New Story. Traditional wear and tear on homes is covered by the families.

NYT on 3D printing | Boing Boing

The NYT covers 3D printing, from the Makerbot and textile printers to custom prosthetic limbs to a mighty house-printer:

A California start-up is even working on building houses. Its printer, which would fit on a tractor-trailer, would use patterns delivered by computer, squirt out layers of special concrete and build entire walls that could be connected to form the basis of a house.

It is manufacturing with a mouse click instead of hammers, nails and, well, workers. Advocates of the technology say that by doing away with manual labor, 3-D printing could revamp the economics of manufacturing and revive American industry as creativity and ingenuity replace labor costs as the main concern around a variety of goods.

"There is nothing to be gained by going overseas except for higher shipping charges," Mr. Summit said.

What is 3D printing and how it can be used! Interesting!

What is 3D printing

3D printing technology was patented in the 80s of the last century, but gained popularity relatively recently. New, promising techniques have been developed and the possibilities of 3D technologies have reached a completely new level. However, to this day, the technique is not known in all circles, and not everyone is aware of what 3D printing is. In today's article, we will try to explain in detail and in an accessible way what 3D printing is and where it is used. nine0005

In short, 3D printing is a technique for manufacturing three-dimensional products based on digital models. Regardless of the specific technology, the essence of the process is the gradual layer-by-layer reproduction of objects.
This process uses a special device - a 3D printer, which prints certain types of materials. More details about it are written here. Other names for the technology are rapid prototyping or additive manufacturing. Often the phrase "additive technologies" is used in the meaning of "3D technologies". nine0005

3D printing steps

To make it clearer what 3D printing is, let's take a look at the playback process step by step. Below are the specific stages of 3D printing. How it works:

  • 3D modeling of the required object is performed according to certain rules;
  • The file with the digital model is loaded into the slicer program, which generates the control code for the 3D printer;
  • Sets required 3D printing options;
  • The code is written to a removable memory that connects to the 3D printer; nine0015
  • 3D model reproduced.

Objects are reproduced gradually. According to the required shape, the selected material is applied layer by layer, forming the finished product. It is worth noting that the possibilities of 3D printing are almost limitless, that is, anything can be made. In some technologies, very thin overhanging elements are provided with supports, thanks to which they can be avoided from sagging.
Naturally, this is a very simplified description of the stages of 3D printing, but they give a very clear idea of ​​the essence of the technique. nine0005

3D Printing Technologies

Different 3D printing technologies are used to reproduce different objects. They differ both in the consumables used, and in the speed and accuracy of printing. Here are the main 3D printing technologies:

  • Fused deposition modeling (FDM) . One of the most common 3D printing technologies, used in most desktop 3D printers, and represents an ideal price / quality ratio. Printing occurs by layer-by-layer supply of a thread of molten plastic;
  • Laser stereolithography (SLA) . The formation of the object occurs due to the layer-by-layer illumination of a liquid photopolymer resin by a laser, which hardens under the influence of radiation. One of the variations of this technology is DLP 3D printing. It uses a special projector instead of a laser. Both 3D printing methods are used to create objects with a high degree of detail. In the case of DLP printing, speed is also an added advantage; nine0015
  • Selective laser sintering (SLS) . Reproduction is performed by layer-by-layer melting of a special powder under the action of laser radiation. This 3D printing method is widely used in the industry for the manufacture of durable metal elements

3D Printing Applications

As you may have guessed by now, 3D printing is extremely versatile. The second name of the technology - rapid prototyping - speaks for itself. In the manufacture of prototypes and models of models, 3D printing can be simply indispensable. It is also a very cost-effective solution for small-scale production. In the aerospace and automotive industries, 3D technologies are already being used with might and main due to the high profitability and speed of manufacturing components. Culinary professionals are working on the development of 3D food printers, and in medicine, 3D printing has become something of a technology of the future. With the help of 3D bioprinting, it is planned to produce bones, organs and living tissues, but for now, implants and full-fledged medicines are printed on 3D printers. Desktop 3D printers can be used for domestic purposes: for repairs, making various household items, and so on. And designers, fashion designers, sculptors and artists appreciate the possibilities of 3D printing and 3D modeling as an unusual way to realize their talent. nine0005

The cost of printing on a 3d printer allows you to use the service not only for commercial and state enterprises, but also for individuals - innovative production technologies have become widely available. Prototyping of 3d models is the reading of information from a computer program by special equipment and translation into a real object by successive building up layer by layer until the formation of a finished product. ProPlast-NN LLC carries out 3d printing to order - the price of is calculated individually depending on the size of the object, the number of ordered samples, the material from which they will be made and the method of prototyping.

3d printing and prototyping - the latest technologies in practice

The combination of computer technology with production allows you to multiply the speed of production, reduce the cost of creating the necessary items. Volumetric printing is developing at a rapid pace, from the realm of fantasy, it has become a familiar production process, which can be carried out using various methods. Order 3d printing in Nizhny Novgorod for one model or batch of products, just call Pro Plast-NN LLC at the numbers listed on the site. The customer will receive a three-dimensional plastic part, made with a high degree of accuracy according to the drawings or based on a real analogue. Small-scale production of products by 3D printing and prototyping is possible.

Where created 3d models and prototypes are used

Prototyping on 3d printers allows you to quickly and at low cost get a sample of the desired part from a polymer material, made with a high degree of accuracy, without roughness or distortion. Depending on the technology used and the material from which the sample is made, the product acquires high-tech properties: ideal shape, strength, plasticity, temperature stability. Models have found application in many areas, so they make custom 3d printing companies of different specializations:

  • medicine;
  • automotive;
  • serial industrial production: mechanical engineering, instrumentation, metallurgy;
  • architecture - when creating models of buildings and complexes;
  • designs;
  • souvenir production.

How 3d prototyping is carried out

The basis for prototyping is a 3d image of an object, compiled by a computer program with three-dimensional modeling functions. nine0046 3d custom prototyping is performed with high accuracy of transferring an image into a physical object using one of several possible methods:

  1. FDM (Fused Deposition Modeling). A moving molten polymer thread forms an object of complex geometric shape in layers, which can subsequently withstand high mechanical and thermal loads.
  2. SLS (Eng. Selective Laser Sintering). This is the sintering of a powder in a container under the targeted action of a laser beam. nine0015
  3. MJM (from the English. Multi Jet Modeling - modeling with many nozzles). Multi-nozzle 3d printer prototyping , applying molten material with multiple inkjet heads, based on the principle of a laser printer.
  4. LOM (from the English Laminated Object Manufacturing - the production of an object by lamination). Bonding layer by layer of thin films, as is done with lamination. After reaching the desired volume with a laser tool, an object of the desired shape is cut out of the mass. nine0015
  5. SLM (from English Selective Laser Melting - selective laser melting). Selective fusion of metal with a targeted laser beam, resulting in a solid object.
  6. EBM (from the English Electron Beam Melting - electron beam melting). Creation of a product from a powder that is melted by a directed electron beam.
  7. STL (from English stereolithography - stereolithography). Purposeful formation of a solid object by a laser beam directed into a container with liquid polymer rubber. nine0015

Benefits of 3d printing and prototyping

What are the advantages and benefits for a customer who decides to order a 3D printing with a printer?

Before launching a new product into mass production, an enterprise can purchase a prototype, test it, make changes to avoid errors in the design development of the product, and reduce the cost of production.

If a private or public enterprise needs to produce a small batch of products, it is more profitable for him to apply for a small-scale prototyping service than to carry out design and engineering development and testing of prototypes, reconfigure production, use labor resources and equipment. nine0046 Printing on a 3D printer at affordable prices will save businesses a significant amount, reduce production costs.

The desired samples can be obtained in a short period, regardless of the degree of complexity of the object being created. Typically, the prototyping process lasts from one to ten days, depending on the specifics of the chosen manufacturing method. You can place an order for 3D printing at Pro Plast-NN LLC - we will answer your questions, calculate the cost, conclude an agreement and print products in a short time. nine0005

The cost of 3d printing with the printer is low, which allows customers to reduce their own costs for design development, testing and sample production. LLC "Pro Plast-NN" makes high-quality 3D printing - the price is calculated by managers individually, depending on the volume, complexity of the work, the chosen manufacturing method and the material from which the sample is printed.

The cost of prototyping and creating 3d models

Answer to question how much it costs to print on a 3d printer depends primarily on the number of ordered products, the material from which the product is made, the size of the object, and the technology of its manufacture.
