Open Stl File In Cinema 4d

At that place are many unlike types of
file formats
for 3D objects: AMF, VRML, OBJ, X3D, PLY, STL, and more than.

There are also many different types of open-source and proprietary
program-specific
files: for Maya, Blender, ZBrush, SketchUp, Cinema 4D, Houdini, etc. These are programs in which you tin can import/consign 3D files and programs that to varying degrees are able to design (manipulate, animate, explode) 3D objects.

Due to this
complexity
of program-specific files
and
various file formats, the i file format y’all should be concerned with is .STL – this is the “de facto” standard for
getting virtual 3D objects to physical 3D printers.

(The list of Maya-compatible data import formats lone is mind-numbing! And you can see why the world of Figurer Science is such a budding field: getting all these things to ‘talk to each other’ requires existent expertise.)

Simply the .STL solitary is not the ‘end all’ to the process. You do not simply ‘plug in’ the .STL into the 3D-printer and it ‘just works’ – the .STL file is but the shape of the object, its outline, its
contours. Whether your file is a simple cylinder or a complex imaginary space vehicle, the .STL alone is merely the shape – and that shape is hollow on the within.

In one case you take the .STL you need to prepare it for 3D-printing. You have to bring the .STL into a software environs and set information technology up for 3D-printing. We telephone call this processimport. (At that place is a reason we don’t call this ‘opening’ the file, which we’ll go into after.) And and then you accept to
slice
the file to turn it into code 3D-printers can understand.

To recap:

Modeling software->

.STL file->

3D-printer software (slice) ->

3D-printed object

In modernistic operating systems .STL files are now natively viewable – that is yous can ‘view’ the contours of the model without sophisticated software. You are only ‘viewing’ the file, like the ‘preview’ of a JPEG image or ‘quicklook’ of a MP3 or MOV file. It will look something like this when you ‘double-click’ the .STL file:

undefined

You can employ your mouse or trackpad to pan around the image.

PRO TIP: If you spend any pregnant amount of fourth dimension with 3D-modeling, you lot will want to invest in an external mouse! You volition notice using 3D software and doing work with 3D models a LOT easier with the aid of an external tracking device versus the limitations of a trackpad.

Continuing with the treefrog model, when the model is static we can zoom in and see its contours:

undefined

You lot can see the round eye isn’t truly round, but is rather a
geometric mesh
of
polygons. (The slight indentation is a representation of the frog’s pupil, non to be confused with the curved profile of the cornea.) Comprised of faces, edges, and vertices, the shapes eventually grade to create the model.
Just not a model with smooth-edge resolution. When the 3D model is exported to .STL you lot will decide at that time how many vertices to use in the .STL – the number of vertices volition determine the number of polygons, the various shapes we see here. More vertices also take more retentivity and creates a larger file size, so therefore more vertices is not necessarily “ameliorate.”

More importantly: If your eventual purpose of the model is a 200 micron resolution print, mayhap a lower number of vertices is acceptable.

(Spoiler: it is.)

Jumping a bit ahead, when the .STL is eventually prepared for printing it loses some of its resolution anyway, due to the nature of turning something comprised of polygons into something in the real world, a physical object. The 3D-printer won’t ‘move’ or ‘print’ each of the polygons – instead the 3D-printer software farther interprets the
contours
of the .STL as a series of moves while extruding plastic
layer by layer. Your model will thus translate to something like this at
the preview stage:

In this preview, the orange tubular paths are the paths of the print head and the user-specified layer height of the extruded textile. (Don’t worry virtually the yellowish & red at this point – in fact don’t worry nigh these colors at all, because they are different for each piece of software.) This preview is up close – and so while you lot may perceive a ‘gap’ between the orange paths remember each of these layers is as sparse as a human being pilus. As you can see in the actual impress (below), the layers stack nicely to course a cohesive impress.

But another point on the ‘preview’ function: this is an of import step during the setup process, because information technology allows you lot to await for potential defects in your print
earlier you go to impress. You can view the path of the print head and all of its anticipated moves, layer by layer. If you lot meet anything wrong
now, you can get back to your original model and fix the fault – in the .STL
or
the print settings – earlier sending the file to print. This could potentially save you hours or even days of piece of work in one case you know what to await for. Conversely, if you lot become a

failed

print, you can go back to your file and the printer settings to preview the print and compare the failed print with that layer in the preview to encounter if you lot can deduce
why it failed.

For this reason it is important to proceed track of your .STL files
along with the printer’s “project” files! Information technology cannot exist stressed enough how of import this pace of the printing process is: it is very important!


.STLs Online

Markets and repositories for .STLs are now common. Repositories (“repos”) tin can exist thought of where people simply put stuff, like storage; and markets are every bit the name implies places where things may potentially be for sale. There are some absolutely stellar gratuitous sites (repos) out at that place, but yous may find yourself fond of a specific designer or maker, and that person may only brand their files available on a premium or pay-per-file market. There are a few adept ‘tiptop-level’ websites (repos & markets), so like most things you will ever notice users in other channels just giving things away on Reddit or sharing with their tight-knit community on Discord. Wherever you go your files from – or desire to share your own! – be sure to give credit where information technology is due. With that said, we like:

  • Thingiverse – with their contempo (Spring 2020) redesign, the Thingiverse website is better than ever! The community is as well extremely strong, spanning years of input and development. Every bit their proper noun implies they are a ‘verse of “things” – thousands of .STL files, broken down into various categories:

  • CGTrader, and MyMiniFactory are two of the all-time ‘markets’ out in that location for .STL files – they also have many free files. They cater to a different audience, but they may likewise accept what y’all’re looking for.
  • Yeggi is also reputable, and STLFinder scrapes multiple STL websites for keywords and displays results – yous can easily go lost here!
  • PrusaPrinters is a swell contender for free .STL files. Launched by the fine folk from Prusa, this is their repository, with a strong community to back it up.

Neither a market nor a repo, r/3Dprinting is Reddit’south channel for 3D-printing everything – files, news, stories, etc. It has a mere 471k global members.


.STLs are
contours
– then what next?

OK then .STLs are outlines of 3D shapes – the
contours
of the shape.

In order to turn a .STL into code that can be interpreted by a 3D-printer, we need to import the file into a
slicer
program &slice
the file, layer by layer.

Import -> Slice
are our next steps!
