prostetic-1273185_1920

At Tripomaker, our mission is to make additive manufacturing accessible to everyone. In the past years we have gathered a tremendous amount of information on the 3D printing sphere and we are willing to share it with you! 

Are you a 3D printing enthusiast and are you getting started with 3D printing yourself? Do you want to learn about the techniques and benefits that bring products to life? Here is an overview of the Types of 3D printing!

Keep reading to the end, we may just have the right thing for you!

Types of 3D printing, a short intro:

Additive manufacturing offers consumers and professionals the ability to create, customize and repair products. When used instead of traditional manufacturing methods it constitutes a great way to save money or time since products are brought to market in days instead of months. For those interested in rapid prototyping, 3D printing is extremely beneficial, allowing designers and businesses to get their products more quickly. How to start? Everyone is looking for a cost-competitive option that will deliver the best performance as efficiently as possible. If you’re not sure what process you need, this blog post will tell you.In today’s blog post we will discuss the seven different types of additive manufacturing processes. Materials can vary from technology to technology, but there are some common features for all additive manufacturing, such as the use of a special 3D modeling software. Step one of every process is the creation of a computer aid design (CAD) sketch. The additive manufacturing device reads data from the CAD file and builds a structure layer by layer from printing material.

1. FDM

The most widely used and cost effective method of 3D printing is a process known as Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF). FDM printers use a thermoplastic polymer filament which is heated to its melting point and then extruded, layer by layer in a cross-hatching fashion to create the desired three dimensional object. This thin layer of plastic cools and hardens immediately binding to the layer beneath it. This process is the primary technology that we will discuss more thoroughly in our blog. If you are interested, stay tuned to our monthly posts!

2. VAT PHOTOPOLYMERIZATION

The VAT Photopolymerization Process is a method in 3D printing that exposes liquid polymers to ultraviolet (UV) light, in order to turn the liquids into solids. Curable resins are used for the process. First, a 3D design is created in a 3D software. Then, the 3D printer is using digital light technology to harden the liquid material layer by layer. This process of draining and exposing to UV light is repeated until the object is complete, leaving a solid 3D object of the desired shape.

The VAT Photopolymerization Process is divided into two distinct technologies whose major difference is the light source:

- The DLP, or Digital Light Processing is using a UV Beamer to solidify the plastic pattern layer by layer.

- The SLA or Stereolithography is using an Ultraviolet Laser to solidify the plastic pattern layer by layer.

3. POLYJET 

PolyJet 3D printing Process is similar to inkjet printing, but instead of jetting drops of ink onto paper, PolyJet uses layers of curable liquid resins onto a build tray. Liquid photopolymer plastic is sprayed for each new layer and is cured once it falls into place. 

3d printing technologies

4. BINDER JETTING

Binder Jetting uses a wide range of material types such us ceramics, polymers and metals. Inkjet print heads apply a liquid bonding agent onto thin layers. By gluing the particles together, the part is built up layer by layer. Parts in full color are possible when a colored print is desired.

3d printing technologies

5. POWDER BED FUSION

The Powder Bed Fusion Process uses polymers, metals, and ceramics and includes the following commonly used techniques:  

- Selective laser sintering (SLS) and Selective laser melting (SLM). This process uses lasers to melt and fuse material powder together.

- Electron beam melting (EBM): During this process the powder bed is selectively melted layer by layer by an electron beam under high vacuum atmosphere. 

3d printing technologies

6. SHEET LAMINATION

The Sheet Lamination Process stacks layered cut-outs and works effectively for paper, polymers and metal. 

3d printing technologies

7. DIRECT ENERGY DEPOSITION

The Direct Energy Deposition Process is comparable to welding,   the material and heat added simultaneously. This method works most effectively with polymers and metals. It is a more complex printing process commonly used to repair or add additional material to existing components.

3d printing technologies

HOW TO CHOOSE THE APPROPRIATE TYPES OF 3D PRINTING?

Each method has its own advantages and drawbacks. The main considerations in choosing a 3D printer are the speed, the precision, the quality, the cost, the choice of the materials and the color possibilities. The VAT and Polyjet processes are mainly used for high-precision and high-quality parts, like jewelry molds. Binder jetting and Power-Bed fusion are versatile enough to use a variety of materials.

At Tripodmaker, we are using Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF) 3D Printers. The material extrusion process is the prominent technique used in desktop 3D printing for three main reasons:

  1. First of all because it’s clean and office friendly. There is no dust, no glue, no sticky liquid resins.
  2. Secondly, it has a low energy consumption as no high-powered laser or compressed air is required.
  3. Last, but not least, it is easy to maintain.

Our products have a full automatic calibration and they are incredibly fast due to our delta robot set-up as well as their limited weight. They come along with a Prisma Software and a heated bed that allows your print to stick better. The Tripodmaker has a rigid high quality designed structure. The resulting accuracy is a combination of hardware, software and extrusion. Getting started with 3D printing? Check out our professional TripodMaker Delta Printer.

CONCLUSION

3D printing may have a profound impact on the world as big as the industrialisation. It is not easy to foresee its long-term impact, but the technology is coming and is likely to disrupt every field it touches. There are many applications for AM technologies including architecture, construction, industrial design, automotive, aerospace, engineering, dental and medical industries, biotech, fashion, footwear, jewelry, eyewear, education, research, food and many other fields that we will discuss on a different blog post. We hope you found this useful!

In this blog, we will talk about where to find 3d printer models free. By now, you may already have chosen the right 3D printer for yourself. Are you wondering how long it will take you before you can make your first 3D model? If you are staring at a blank screen with no idea what comes next, there is nothing to worry about. At Tripodmaker our mission is to make 3D printing accessible to everyone. The process of preparing a 3D model for printing is often unique to everyone, but hopefully these guidelines will provide a foundation for you. So go ahead, read our article or download our e-book now! 

 

GENERATING YOUR CAD MODEL

To get started with 3D printing, you first need to design the 3D object. In the additive manufacturing industry people say: “If you can draw it, you can make it.” A great deal of items can be made with 3D printers. You can draw them yourself or you can easily download object files from various websites. 

DRAW IT YOURSELF

If you want to draw/design the 3D object yourself, there are free and paid software available online, which range in complexity. You can review Wikipedia for a list of 3D modeling software applications or read our selection below. You can learn how to 3D model starting with free 3D modeling software like Rhino, Blender or SketchUp. It will take you some weeks to be familiar with 3D modeling tools such as the aforementioned. To become a professional user will take you at least half a year to study and practice.

 

GOOGLE SKETCHUP

link

This is a fun, free and easy to use software. To build models in SketchUp, you draw lines and shapes using a few simple tools that you can learn in a short time. With the Push/Pull tool, for instance, you can turn surfaces into 3D forms. Very easy to learn and intuitive, it offers the possibility to be productive within a couple of hours.

3DTIN

link

3DTin is a free web-based program for creating three dimensional models. You can draw directly from your browser. 3DTin offers templates that you can use to develop models or you can just as well design a model from scratch by placing cubes of different colors on top of each other. The service is free to use as long as you allow your models to be labeled with a Creative Commons license and put them in the 3DTin gallery. The gallery is a great place to find examples of what can be created in 3DTin. Models that you create can be exported in standard 3D file formats (STL for instance) in order to be used in other modeling software. You can also save the sketches in cloud. 3DTin could be a great tool for engineering or architecture activity or even for teaching students.

BLENDER

link

If you are looking to create an artistic 3D model, this is the right software program for you. Blender is the free open source 3D content creation suite, available for Linux, Mac and Windows. It is a powerful software offering lots of design freedom and endless design options, however it might be quite difficult to learn. It is typically used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games. This software is a nice tool for fixing and making simple changes to STL files.

OPENSCAD

link

OpenSCAD is a software for creating solid 3D CAD (Computer-aided design) objects. It is free software and available for Linux/UNIX, MS Windows and Mac OS X. It might be the application you are looking for when you are planning to create 3D models of machine parts since it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. It is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. This gives to the user full control over the modelling process and enables him to easily change any step in the modelling process or make designs that are defined by configurable parameters.

COMMERCIAL SOFTWARE

Commercial software such as CAD software AutoCAD and Pro Engineer, as well as software packages Rhino, Maya, and SolidWorks are all pretty good for designing 3D models, if money is not the issue. Rhino is incredibly easy to use, thanks to its combination of a command-line and toolbar interface, and extreme flexibility regarding order of operations. The end result is a 3D software that feels intuitive and solid. Maya is the current king-of-the-hill in high-end 3D animation software. It offers a comprehensive creative feature set on a highly extensible production platform. When it comes to SolidWorks, it is simple enough to deduce and work with limited to no experience but still powerful enough to model any engineering problem that might crop up.

How much do 3D printers cost?

The answer to the question "how much do 3d printers cost" comes down to how fast you want to get to printing and to your budget. Let’s take a look at the various price points.

Depending on your budget, you might consider spending a bit more if you want to get started with printing fast.

The more money you invest, the faster you will get going eventually.

We at Tripodmaker made an overview on what to expect from a certain budget when you aks: how much are 3D printers. You can find the complete overview in our downloadable ebook.

A short overview: How much do 3D printers cost?

Below €600 assembled machines

typically have proprietary cartridges. You need to be aware of the ‘bait and switch’ with these machines. The machine appears affordable, but the print head is quite expensive. And at this price point the print quality level can’t match the higher costing machines.

€600 to €1000 machines:

these are DIY devices and you have to source all the parts (mechanical and electrical) yourself, rely on your technical knowledge to assemble the printer and get it working. Needless to say this is not easy, but the print quality can be quite high with these machines (depending on the parts used).

€1000 to €1700 machines:

you purchase a kit from a supplier and assemble the printer yourself with detailed instructions - think of this as an advanced Ikea set. It will take you 12 to 24 hours to assemble the machine and get it up and running smoothly.

€1750 to €3500 machines:

these are fully assembled machines and depending on the price you might have a panoply of features. Some of the features include a heated bed, dual nozzle print heads, auto-calibration and robust proprietary operational software.

AI33_005_c4d_rearranged_GherkinBuilding_1200x628v1

 

€3500 and above machines:

we’re not qualified to discuss machines in this price range as they are primarily for industrial use. They use special materials and have extensive service contracts. These machines consist of heated build chambers up to 100 °C and require expensive parts that are reliable at these high temperatures.

10 Best 3D prints

useful things to 3D print

10 Best 3D prints

3D printing creates plenty of professional opportunities for architects, engineers, product developers and more. However, it can also create lots of objects for day to day use. What are the best 3d prints? A great side effect of owning a 3D printer or having access to one, is that there are already a lot of product designs available online to download for free. That means you can simply print it with little to no effort, instead of going to the store and spending money. Careful out there: there are a lot of useless and amateurish creations. That's why we made a list of stuff that's actually useful, fun and print-worthy. 

1. CABLE ORGANISERS & ELECTRIC OUTLET ACCESSORIES

These small cable and electricity accessories make cheap and quick prints. Although the original items are not that pricey, some of them can cost up to and over € 10. Add some shipping fees or a trip to the store, and your 3D printer wins on both speed and budget.

2. PHONE ACCESSORIES

Phone cases can be printed in just an hour or two, at only a few cents per piece. Why not try a different one every day? Other accessories like phone docks, car vent clips or phone stands are also useful gadgets that can be printed at a stunning 1/10 of the retail price.  

3. DESK ACCESSORIES

Tired of keeping your pens in a mug? It's your lucky day! There are plenty of product designs available online, ranging from stylish to creative, to spruce up your office space. From simple pen holders to stationary like tape dispensers, rulers, paperclips etc..., the cost to print these objects can beat retail price anytime by 1/3. 

4. TOOLS

Never fear an emergency: you can always print tools. If a plastic wrench is durable enough for astronauts, imagine what it can do for you. Not in the least: save a few bucks. Not all tools have to be tough though, like golden ratio calipers and other measuring tools. Again, definitely worth it to print.

5. PIGGY BANKS

Piggy banks today come in more shapes and sizes as they ever did, thanks to 3D printing. Take a look on Thingiverse and be amazed by all the possibilities. The downside can be the printing time and cost for the larger ones. The cost of bigger volumes can match the cost of the purchase of a piggy bank in the store. Still, the ones you print will always be more unique.

6. TOYS

Let's not forget the little ones. With 3D printing a child's imagination will run wild. A new creative lego piece, a bowling set, accessories for other toys like Sphero, board games, etc..., will make your 3D printer run 24/7. Don't worry about the running costs: they won't be that dramatic. Find an overview of complete costs in our infographic on our blog here.

7. CHRISTMAS DECORATIONS

Not too crazy about the Christmas decorations in stores or online? 3D printing can be your red-nosed friend here. Ornaments, lighting, napkin rings, the entire Christmas spirit can be printed. The possibilities are so endless, you'll be staring at different styles every year. Watch our use case with some truly inspiring Christmas decorations here. 

8. HOME ACCESSORIES

Having some sweet visitors over who brought flowers? But forgot the vase? Have one printed during their stay. Other home accessories are both cheaper to print and unique in design as well. So next time you're at the store, you'll think twice about buying candle holders, expensive bottle stands and designer chess sets.

9. LIGHTING

Finding the right lighting that matches your taste can be tricky. The really nice ones are so overpriced that just a bulb hanging from your ceiling suddenly doesn't look that shabby. Not when owning a 3D printer. There are some stunning designs available for free and at the cost of an Ikea lamp (or cheaper) you will have a designer lampshade to amaze your friends and family. 

10. FURNITURE

At Tripodmaker, we firmly believe you should not print all your furniture. But a small chair for the little ones can be a good start at a reasonable cost. Step 2 would be to try some of the great Ikea hacks out there. If your printer still has some free time, which we hardly believe at this point, you could try a chair set or some modular connectors to create storage, shelves and drawers. Mmm. Maybe it's time to get a second printer?
