Market demand for 3D printing & 3D printers continues to expand, with a wide range of industries from Medicine to Aerospace adopting 3D printing in their operations.This market expansion & the need to cater diverse product & design requirements across industries has resulted in a host of new 3D printing materials to be discovered.Plastics offer the advantage of multiple applications for products from ranging from utensils, toys & action figures to household fixtures.Polysastic Acid or PLA filaments are eco-friendly, as they are sourced form natural products.PVA & PC however do not offer the range of applications provided by PLA or ABS due to lower strength & are often low-cost alternatives.Resins are also used as 3D printing materials, but have less flexibility & strength as compared to plastics.
From printing thermoplastics to metals, 3D printers can now print your favourite food.It is important for the food item being printed, that the build material should emerge smoothly from the nozzle & it must maintain its shape upon deposition.This method of direct deposition allows creation of intricate & detailed designs of food, as opposed to traditional tools like moulds, which are cost effective for quantity production, but offer little to no design intricacy.Due to the amazing detail SLA brings to 3D printing, it is possible to add detail & customization to foods that was once only possible for skilled artisans.A 3D printer can help determine the exact quantity of vitamins, carbohydrates, fats as per the user’s age & health requirement.It also helps people with no cooking skills to cook highly accurate recipes while saving time & energy, often demanded by traditional cooking methods.

A few examples of 3D printed houses & offices do exist, but 3D Construction is a long way from being the default technique of constructing houses or structures. 3D printers may also print or pre-fabricate parts of a building in a factory which can then be put together later at the construction site. 3D printing can help the Construction embrace the ‘lean’ concept of manufacturing. 3D printers on the other hand only use materials required to print the structure, drastically reducing cost & generating zero waste. The same applies to construction where buildings with unique architecture can be 3D printed, something traditional methods may find challenging. Although the idea of 3D printing houses or buildings sounds appealing, the technology is still at a nascent stage in the industry & wide-scale adoption remains mired with several hurdles.
With 3D printing already playing a crucial role in the production of low-cost satellites and lighter, efficient rockets, its role in future human space travel & interplanetary colonization is critical, to say the least.Space is the not the ultimate frontier for humans anymore, inter-planetary travel is.This makes overcoming the high per kilogram cost of required to escape Earth’s gravity a barrier for most launches.This can be achieved by printing lighter parts for launch vehicles by using weight optimised geometries and printing parts in space itself at the point of need, like in the International Space Station.With 3D printing already revolutionizing the space industry, increased process automation for batch series or single item production will help reduce the overall cost and production time for making satellites, rockets and other space gears like probes and drones.This also extends to the manufacturing of space faring aircraft as well, in addition to in-space platforms, ground equipment, launch services and independent space RInter-planetary travel demands the construction of human habitats on alien worlds.Carrying bulky pre-fabricated parts for such habitats in to space will not only inflate the budget for such inter-planetary missions, but also delay their completion.

3D printing and has gained more equity as a sustainable solution to immediate and custom manufacturing needs during the COVID crisis. Innovations like Block chain, IOT, hi-speed 3d printers and metal 3D printing are some of the key drivers of growth in the 3D printing field. In this blog we will try and outline a few major trends that are expected in the 3D printing industry in 2021.Growth incentivized by application driven approachAn estimated 20% of global consumer goods are expected to use 3D printing for custom made products. This projection is based on the amazing transformative power of 3D printing that can be harnessed by applications and software tailor made to specific 3D printing needs.Reduced Operator InterventionAdvances in 3D printing help manufacturers to focus on processes in the post and pre-production phases. As the models to be printed can be designed virtually, simulation and automation software in tandem with 3D printing will enable better designs with minimal human intervention, while speeding up the manufacturing process.Assimilation of 3D printing in Supply Chains3D printing has great potential to handle resource-intensive tasks. With shorter lead times and fewer equipment needs it has already revolutionized the manufacturing supply chain.
3D printing uses computer models to print objects layer by layer.Laboratories around the world are deploying this technology to speed up traditional research methods and make them more productive.One way 3D printing helps researchers is by reducing the cost of equipment involved in research.3D printing plastic parts and components is cheaper and faster than waiting for them to be made and delivered by an outside vendor.Hence they can be used as consumable items, that are put to use once and discarded without the need for clean ups.3D printing and printers are becoming a standard tool for scientific research, helping scientists to fabricate parts custom made for an experiment.They also help in replacing damaged parts of a certain apparatus in a clean, cheap manner.3D printers also make it easy to make life size models of molecules and atoms, helping researchers to better understand the materials involved in their experiments.3D printing also helps researchers in medicine to print life like models of a body part or organs to study and practice complex surgical procedures.
3D printing is on course to change manufacturing forever, among other sectors like healthcare, defense, education and construction to name a few.Better detail, more efficient use of materials resulting in less waste, effortless modelling are just some of the advantages that make 3D printing a fitting alternative to current manufacturing practices.Adoption of 3D printing on a wide scale across the industrial and domestic spectrum however, has been fueled largely by three major technologies.This done layer by layer until the model acquires the desired shape, following which the layers are fused together.A wide range of plastics, metals and composites can be used to print objects using FDM, making it the most widely adopted 3D printing technology today.Stereolithography was one of the first 3D printing technologies to be used.Invented in the 1980s, Stereolithograhy (SLA) produces parts with high resolution, smooth surface finish and accuracy.SLA uses a technique known as ‘photo-polymerization’ to print 3D models.
Selective Laser Sintering (SLS)Fused Deposition Modelling (FDM) is the focus of this particular blog.3D printing using FDM essentially implies that the object being printed is fused together by printing layer after layer in a certain pattern.Objects are created by extruding layer upon layer of the heated material on the build tray or printing bed of the 3D printer.FDM 3D printers use a filament of certain material, usually plastic, which is passed through a hot end, to melt.The melted filament material is used to make layers which are then fused together to give the object its final shape.A wide variety of materials can be used for FDM 3D printing like plastics, pastes and some metals as well.FDM 3D printers can be fitted with a wide variety of extrusion systems or extruders like filament extruders, pellet extruders, chocolate extruders and paste extruders depending on the required model to be printed.Scalability is the biggest advantage of using the FDM technique for 3D printing.None of the other available 3D printing techniques like SLS and SLA, can be scaled like FDM, without major issues propping up.
The origins of 3D printing can however be traced back to over 30 years ago during the 1980s.One of the first patents filed for rapid prototyping was by Dr. Kodama in Japan.Dr. Kodama however was unable to obtain a patent due to some delays.On the other hand, Charles Hull, who co-founded the company 3D Systems, successfully filed a patent for a technology known as Stereolithography Apparatus or Stereolithography as it is known today, in 1986.However, the research only yielded processes that were good for prototyping purposes and hence the technology was limited when it came to printing original 3D models.Early 2000s saw the rise of industrial 3D printers, which were suited to building complex parts, with high value and complex geometry.Around the same time, low cost 3D printers useful for concept modelling and functional prototyping arrived on the scene.
Photo polymer resins like clear resin, standard resin, to name a few, are used to make prototypes in SLA.These resins, or ‘build materials’ as they are called are in a liquid state.A part’s entire cross section is traversed by the laser as it builds up each layer.SLA is better suited to printing parts with small and well defined features.When printed using SLA, parts generally yield higher dimensional tolerances a better surface finish.SLA presents a challenge when printing larger parts, as they need support during the printing process.The technique uses polyamide and polystyrene powders as building materials.Layers of the materials are carefully on the build tray using a leveler or roller.
1.Choose a reliable printer with an upgraded roomWhat factors will a Newbie consider before he/she is going to get started to do 3D printing?Practicability, reliability, and affordable price are factors worth being considered.Starting with a pre-assembly process, makers can get a comprehensive understanding of 3D printers and their accessories.Scale down or hollow out your modelIf it doesn’t necessarily require a big size or solid structure for your prints, scaling down or hollowing out your model will substantially decrease the cost.3.Eliminate unnecessary support structureIt is commonly known that prints can’t stand naturally on the hotbed if the model is designed with some angles.Support is necessary for FDM printing, but cost materials and more time, even additional post-processing for further smoothness and polish.
There are mushrooms that grow faster than 3D prints.” With two-year research collaborated with his partner on the 3D printing area, Joseph DeSimone shared the research findings at TED talks.Besides, the layer by layer process leads to defects properties.Moreover, material choices are far too limited.They pondered over all those questions and problems faced by 3D printing when they got inspired by a Terminator 2 scene from T-1000.A very special window is not only transparent but also oxygen permeable.With the special window, we can let oxygen enter from the bottom.
But speaking of molding utility, DLP technology is more complex and more adaptable for the dental or Jewelry mold.Resin 3d printing is known for its great ability to achieve very nice, highly detailed parts, all thanks to a technology called vat polymerization.Of course, both of them are used resin and light source to make parts, the comparative difference mainly is the light source type which use to cure the resin.The process  An SLA 3D printer consists of a vat (a resin tank), a build platform, and an elevator— used for moving the build platform upwards or downwards— a light source and a pair of galvanometers.When starting a 3D print on a “top-down” SLA 3D printer, there’s a single layer of resin on the build platform.A DMD contains hundreds of thousands or even millions of small micro mirrors that direct the light and create the pattern of a layer.
The 3D printer features high speed and high utilization rate.Although the digital operation mode has low fault rate, if the fault appears, it will not only affect the printing quality, but also waste time and filaments, and even damage the machine.At present, the most common fault of 3D printer is that the nozzle is blocked and cannot discharge.There are several reasons and solutions about nozzle fault.Given below are some of the reasons for nozzle blockage and their solutions:-Reason 1The residual filaments solidify and block the nozzle because the nozzle is not cleaned in time after printing.Solution 1First, heat the nozzle to the normal melting temperature of printing consumables; then try to insert the wire into the nozzle manually.Normally, the downward pressure of manual feeding can penetrate the consumable line and bring out the blocked debris;Finally, if the nozzle still fails to work, try to use a 1.5mm hexagonal wrench to dredge the throat or nozzle.
Till recently, the process of transforming a 3D printed things right into a ready-to-use item was still laborious belief, for instance, of manually cutting tags or other assistance structures, or sanding, polishing as well as over painting.The series of applications for 3D printers is becoming even broader.This is why we hear a lot regarding innovative tasks in aerospace, the production market as well as clinical scientific research.Equally as fascinating is the introduction of full-color 3D inkjet technology, which can be used to publish 3D objects in no less than 10 million colors.Printing models in full colorThe UV led inkjet print technology advertises the development significantly.The product is equally as hard as ABS, making it ideal for various applications, and similar to traditional inkjet printers, it can also create more than 10 million colors.There are indeed numerous 3D printers on the marketplace, however, they mainly differ in facets like the print resolution and sorts of product they sustain.
