SCANNING
MAKERBOT DIGITALIZER
I made a small bird in oil clay and I scaned in MakerBot Digitizer. I used MeshMixer for improve the final product.
XBOX 360 AND SKANECT
Another exercise used Xbox 360 Scan. We scaned us in Skanect software and edited in Meshmixer
MESHMIXER
MeshMixer is free 3D modeling software that allows you to easily create and correct 3D models. Its specialty is creating 3D models on the basis of existing volumes, which are combined using easy-to-use tools.
Import your .obj file
Erase strange object: Select object and delete.
For Plane cut, you can use Edit/Plane Cut, move plane and Accept.
Smooth surfaces of an object: Use Scupt tool and Brushes option.
I will print my image in Dimension 3D Printer, but it was broken down printer
PRINTING
SUBSTRACTIVE OR ADITIVE?
The technique of making a 3D printer is additive - most of them use a hot plastic extruder to "print" a plastic model. This contrasts with the subtractive manufacturing tools, which start with a solid block of material and use a cutter to remove the excess. Subtractive fabrication is much more common than the additive, especially when working with metal and wood. Lathes, milling machines, mills, saws, drills and other CNCs like laser and vinyl cutters are all subtraction tools.
DESADVANTAGE SUSTRACTIVE FORM
Milling causes waste, and without some sort of dust control, such waste will be thrown all over the room.
Milling is more dangerous - while it is possible for a plastic extrusion machine to overheat and catch fire, a CNC router is not spared from this, in addition to the added danger involved in a rotating blade at 20,000 rpm sending pieces of itself, or even the workpiece, flying towards you.
A router is necessarily larger and heavier than a 3D printer and therefore more expensive and more difficult to move. A positioning system is required that can maintain precision when facing resistance, and powerful enough motors to drive it.
Software preparation is also more complex for milling. After drawing in a CAD or 3D modeling program the object you want to do, it is necessary to generate the toolpaths using Computer Assisted Manufacturing (CAM). This involves specifying the dimensions and location of the raw material, the dimensions and characteristics of the spindle (cutter), and speeds of the shafts and the spindle. The tools to do this are complex, and a bit daunting for the user who does it for the first time.
ADVANTAGES ADDITIVE FORM
Home 3D printers are improving often there is still a lot of tweaking and experimentation involved in getting a good impression.
It is cheaper to work with wood than with plastic, and you are likely to get substantially higher results.
On the other hand, making complex objects in 3D is much more complicated with CNC milling than with a 3D printer. There are free tools for 2.5D milling, but CAM software for 3D milling can be very expensive and difficult to use.
Doing 3D work for 3D printing is a lot easier. You can design your models in a free program like SketchUp or Inventor Fusion, and then export an STL file. The slice software automatically converts the STL file into toolpaths in G code, then sends the G code directly to your 3D printer.
ULTIMAKER
I used Ultimaker2 3D Printer for print the little bird. Ultimaker has 120x120x115 mm built volume. Support PLA material (2.85mm diameter). Support STL, OBJ and AMF files types.
For Ultimaker, you need CURA SOFTWARE from ULTIMAKER web page here
TOOLS
INFILL
Infill is type of fill that you will use.
1. EMPTY: Infill will Leave you model hollow with low strength
2. LIGHT (20%): Infill will Leave you model an averange strength
3. DENSE (50%): Infill will give you model an above averange strength
4. SOLID (100%): Infill will make your model completly solid
5. GRADUAL: Infill will gradually increase the amount of infill toward the top
GENERAL SUPPORT
Generate structures to support parts of the models which have overhangs. Without these structures, such parts would collapse during printing.
BUILT PLATE ADHESION
Enable printing a brim or raft. This will add a flat area around or under your object which is easy to cut off afterwards
MATERIALS
Nylon: Used by many manufacturers worldwide, Nylon (polyamide) is well-known for its impressive durability, high strength-to-weight ratio, flexibility, low friction, and corrosion resistance. With its ability to withstand significant mechanical stress, Nylon is a great choice for 3D printing tools, functional prototypes, and end-use parts.
ABS: Used by an array of industries worldwide, ABS (acrylonitrile butadiene styrene) is known for its exceptional mechanical properties. Specifically formulated to minimize warping and ensure consistent interlayer adhesion, our ABS allows the creation of functional prototypes and complex end-use parts with ease.
PLA: PLA, or Poly Lactic Acid, is made from organic material — specifically cornstarch and sugarcane. This makes the material both easier and safer to use, while giving it a smoother and shinier appearance that’s more aesthetically pleasing. The thermoplastic is also more pleasant on the nose, as the sugar-based material smells slightly sweet when heated opposed to the harsh smell often associated with ABS. However, while PLA might seem like a better overall choice at first glance, it features a far lower melting point than ABS. This means that using printed parts for mechanical operations, or even storing them in high-temperature locations, can result in the part warping, cracking, or melting. The material is also weaker than ABS, though, it can achieve a superior level of print detail and is less prone to errors while printing.
CPE: CPE (co-polyester) materials are chemical resistant, tough and demonstrate good dimensional stability. It is a preferred choice for both functional prototypes and mechanical parts. While both CPE and CPE+ provide similar performance characteristics, CPE+ provides the added benefit of higher temperature resistance and increased impact strength.
PVA: PVA (polyvinyl alcohol) is a water soluble support material for multi-extrusion 3D printing. With a good thermal stability, Ultimaker PVA is ideal for printing complex models that require supports for large overhangs, deep internal cavities, and intricate geometries. Designed for a seamless 3D printing experience, our PVA provides good adhesion to both PLA and Nylon. Available in 350g and 750g spools.
PC: With Ultimaker PC (polycarbonate) filament, you can print strong and tough parts that retain dimensional stability when subjected to temperatures as high as 110 ºC. Our PC is a perfect filament for printing molds, tools, functional prototypes and parts for short-run manufacturing.
TPU 95A:Highly versatile for industrial applications, TPU 95A (thermoplastic polyurethane) filament is the go-to choice for a wide array of manufacturing projects that demand the qualities of both rubber and plastic. Designed for 3D printing consistency, TPU 95A is a semi-flexible and chemical resistant filament with strong layer bonding. In addition, it is easier and faster to print than other TPU filaments.
HOW IT WORKS
1. You need copy in SD Card printing file.
2. Settings you model
3. Wait to warm head and plate
4. let it works
CONCLUTIONS
Many 3D printers exist in market, from basic to havy duty. You can elect by work taht you make. If possible, you choise will be better.
Material is important because You should consider the mechanical properties of each piece. The pieces that will be in demanding environments will be of a type of material, while the decorative works or that will not be exposed to external forces, will be of a different material
You should see the best software to do 3D work, some have advantages over others in certain aspects, so we must consider our needs. Personally, I've decided to learn more about SolidWorks software.
