3D Printing with SketchUp: 10 Tips and Tricks

by Fabian | March 30, 2017

SketchUp is one of the most popular 3D modeling & design programs for 3D printing, as we found out from our analysis. However, preparing a SketchUp model for 3D printing can be a little tricky. That’s why we put together a list of 10 simple yet effective tips and tricks to make your SketchUp design 3D printable.

1: Set your Template to Millimeters or Inches

Some simple clicks before getting started will make your life easier: you may want to set your SketchUp template to metric or imperial units. This way, you won’t need to re-scale the printing size of your model later.

You can change the template by clicking on Window > Preferences > Template and selecting ‘3D Printing – Millimeters’ or ‘3D Printing – Inches’.

2: Install the SketchUp STL Extension

Typically you can save your 3D model as a SketchUp file (SKP). Even though our online 3D printing service accepts these files, you might want to get SketchUp’s free STL Extension. The STL file format is the most commonly used in the 3D printing community and will make it easier to share, print, and edit your design in other software.

With the SketchUp STL extension installed you can export your model as an STL file. Make sure to select the same unit type that you chose in your template (millimeters or inches) when exporting, and choose the binary file format to reduce the size of your file.

3: Avoid Paper-Thin Surfaces & Set Wall Thicknesses

In order to make your SketchUp model printable, you need to ensure that each and every surface has a wall thickness. Without setting a wall thickness, a 3D printer has no information about how thick or how thin it is supposed to print your part.

The picture below shows a model with paper-thin surfaces (not printable, left) and a solid object with thick walls (printable, right). If you want to learn more about how thick your walls need to be exactly, make sure to read this blog post.

4: Make Your Model Watertight (Manifold)

A printable model must not feature any holes in its surface. Ask yourself the question: if I were to put water inside my model, would it flow out? If that’s the case you need to find these holes and close them. This is one of the trickiest parts of creating 3D printable models in SketchUp.

The design below is an example of a model that is not watertight. You can clearly see that there is one big hole on its surface.

Once this hole is closed (for example by drawing new lines), SketchUp recognizes that the object is solid on the inside and ready for the printer! You can see such a watertight (also referred to as manifold) object below.

5: Avoid Internal Overlapping

Intersections and walls within your design can make your life difficult since your model needs to have one continuous ‘outer shell’. That’s why it makes sense to think about your model in a 2-dimensional space first.

In the case below, the left shape will not be printable once it is pulled into a 3-dimensional object since it will feature paper-thin walls within the object. The shape on the right, however, won’t be a problem to print once it is pulled into a 3D object because it will only have one ‘shell’. It doesn’t feature paper-thin walls on the inside. We’ll look at an automatic way to create one outer shell later.

6: Check if Your Model Is Solid

Creating watertight models with one continuous outside can be tough sometimes. Luckily SketchUp lets you check if you made any mistakes.

Here’s how it works:

Triple-click on your model with the select tool (this will select everything).
Right-click on your object and select ‘Make Group’.
Right-click on your object again and select ‘Entity Info’.

If you designed an object with holes (not watertight) and internal intersection (not in one shell) the Entity Info window will say ‘Group’. This means that your model is not printable and you’ll have to check it again. Right-click on it and select ‘Explode’ to re-edit the components.

If you designed a watertight model in one shell, the Entity Info window will say ‘Solid Group’ and then you know that your model is ready to be 3D printed (in the next steps we’ll tell you how to fix this).

7: Look inside Your Model with the ‘Hide Tool’ and ‘X-Ray-Mode’

Looking at your model from the outside means that the inside is a ‘black box’ for you. However, even the inside of your model could feature many modeling mistakes that would make your object unprintable. In the example below, the ‘Entity Info’ window indicates that the object is not solid.

Since it looks solid from the outside, it makes sense to take a look at what’s going on inside. Select a surface (face) you want to hide and select ‘Edit’ > ‘Hide’. And voila: you can find the trouble-making mistake. Alternatively, you can switch into x-ray-mode by clicking on ‘View’ > ‘Face Style’ > ‘X-ray’.

8: Create an ‘Outer Shell’

We already pointed out that designs with overlapping objects create problems for 3D printers. The good news: there’s an automated solution for creating one ‘outer shell’ around the overlapping objects, deleting all internal overlapping parts.

To start with, we have these two solid blocks. Each of these blocks was ‘grouped’ separately (Select > Right click > Make Group). We also selected the x-ray view to make things easier.

We then move one block into the other. We now have overlapping areas in the interior of this object.

To get rid of these, we select one block, click on ‘Tools’ and choose ‘Outer Shell’.

The last thing to do is to click on the second block. SketchUp automatically created one solid group out of these blocks. As you can see, the internal overlapping parts are gone. The result is a new solid object that is ready to be 3D printed!

9: Fix Reversed Faces (Inverted Normals)

Another problem that can occur is so-called inward-facing or reversed faces. This means that a surface of your model is facing in the wrong direction (typically this means that it is facing the inside of the object instead of the outside). These surfaces are automatically colored in light blue.

To fix this, right-click on the inward-facing surface (face) and select ‘Reverse Faces’. You can see an example of this in the image below (left). On the right, you can see the object how it is supposed to be: all faces point to the outside again.

10: Increase Circle/Arc Segments to Getting Smooth Curves

SketchUp ‘smoothens’ arcs and circles in its visual presentation. Even though circles might look perfectly spherical in SketchUp, they are actually only made of 24 sides. Click on ‘View’ > ‘Hidden Geometry’ to see theses sides. When being printed, this circle might come out quite edged.

When you select the arc or curve tool, SketchUp will show you their default sides in the bottom right corner. You can then enter a higher number to increase the number of sides. Validate your entry by hitting the ‘Enter’ key and then draw your arc or circle.

The image below shows a comparison between the default 24 sides (left) and 150 sides (right).

Extra: Automatic File Fixing and Preparation

Sometimes problems are tiny and hard to see with the naked eye. There are SketchUp extensions like the Solid Inspector 2 that find problems automatically and point them out to you. Simply select a group or component and activate the Solid Inspector tool for an analysis of what would prevent it from being a solid manifold.

Another handy extension is CleanUp 3. It allows you to cleans up and optimize your SketchUp model with handy tools like “Erase hidden geometry” and “Erase duplicate faces”.

Also, SketchUp added a cool feature to their 3D Warehouse that was developed by Materialise. When uploading a model to the 3D Warehouse, you can check the “I want this to be 3D printable” button (see video below) to get modeling errors fixed instantly. This tool will make your 3D model watertight and allow you to download it as an STL file. While it might lead to somewhat less accurate results, it’s a very fast way to get a printable file. So if you’re searching for an easy-to-use tool that will save you a lot of time and effort (no more searching for file issues, no more exhausting fixing sessions), this is the tool for you.

Extra 2: Getting Your High-Quality 3D Print

Did you manage to follow our tips and tricks and create a printable SketchUp file? In order to send it to our printers, download the SketchUp 3D print service plugin. Alternatively, you can upload your models here and choose from hundreds of material options.

Is SketchUp good for 3D printing? – 3D Solved

Have you ever come across a model you would like to modify so it can meet a specific requirement of yours? If you ever felt the need to modify an existing model or to create your very own designs, then you surely saw there are a lot of programs to help you achieve that.

There are quite a few CAD software options to choose from and all of them have their own strengths and weaknesses, so I made this article to help you decide if SketchUp is the right one for you.

SketchUp is a great tool for beginners with little to no experience in the 3D modeling world. With SketchUp, you will be modeling your designs right away for free without the need to download anything. Although the learning curve is friendly for newcomers, professional modelers will be limited by the lack of advanced functionalities.

Is SketchUp easy to learn?

SketchUp is considered by most users to be one of the easiest 3D CAD modeling programs to get started in the 3D designing world. It is possible to achieve a fairly decent skillset with the software in no time and with little difficulty. This is because of its user-friendly interface, which is very intuitive to pick up, even for someone without a 3D modeling background.

With SketchUp, 3D modeling is made simple but its narrow focus makes it more difficult when it comes to complex designs. For that reason, SketchUp is better suited for beginners or intermediate users. If all you want is to 3D model simple objects, just watch a SketchUp tutorial and you can start designing right away.

Is SketchUp popular in 3D printing?

SketchUp is a popular 3D modeling program amongst makers. The fact that it provides a free version, combined with its user-friendly interface makes it a solid choice for beginners and intermediate users. You don’t even have to download the software as it is browser-based. Just sign in on SketchUp’s website and start designing!

With SketchUp, you can transform your ideas into 3D models easily thus making it an excellent tool for both visualizing and planning. The SketchUp Viewer mobile app is also available for free and allows users to see their designs in the place it would be built using augmented reality (AR).

Sketchup’s mobile app allows for augmented reality object visualizations

Can you design anything using SketchUp?

SketchUp can be used in a variety of projects, from buildings to 3D printable product mockups. It is a great tool for 3D modeling projects across architectural and interior design.

Since SketchUp uses straight-line segments to build forms it is not advised to use it on organic designs such as plants and animals. You will have a hard time modeling any curved or irregular lines. If you are interested in organic modeling you should consider another CAD program, like Blender or ZBrush.

Many hobbyists choose SketchUp as it is free and easy to use, but take into consideration that complex modeling and drafting customization can be troublesome because of SketchUp’s narrow focus.

Online resources for learning SketchUp

As it happens with all the popular 3D CAD programs, there are a lot of good sources providing educational content to help you learn everything you need to know to start modeling with SketchUp.

Besides the community-driven content, the SketchUp developers provide amazing official resources to learn the program. Just access SketchUp’s website for free courses covering most features of the software.

You can also find great tips and tutorials on SketchUp’s official YoutTube channel. Also, I found this channel to have good updated videos teaching SketchUp, you might want to check this video series to get started.

Popular alternatives to SketchUp

SketchUp vs Tinkercad

Tinkercad is a totally free browser-based 3D design software. There is no offline version, so you need an internet connection to be able to use it. Both Tinkercad and SketchUp provide people without any experience in 3D modeling the opportunity to design real objects that come out of the 3D printer.

Tinkercad limits your options with their preset catalog of shapes and is more oriented towards introducing kids to the 3D modeling world. With SketchUp, you have more freedom to create new designs as it has more advanced features, allowing you to further express your creativity.

I would recommend SketchUp to anyone who finds Tinkercad as too basic and wants to explore more advanced options, but still has very little experience with 3D modeling. If you want to learn more about Tinkercad, you can check out the review I made!

SketchUp vs FreeCAD

FreeCAD is a completely free open-source parametric 3D modeling software. Being that FreeCAD is fully parametric means that it is not very practical to use it to model organic figures such as plants and animals.

FreeCAD is best used when it comes to mechanical purposes, precise replacement parts, and elaborated technical objects, whereas SketchUp is primarily used in construction and interior design.

When it comes to ease of use, SketchUp’s interface is way more user-friendly and intuitive than FreeCAD’s. So it would be easier for someone taking their first steps in 3D modeling to start with SketchUp.

I also wrote a review of FreeCad, so make sure to check it out if you are still on the fence.

SketchUp vs Fusion 360

Fusion 360 is a desktop-installed and cloud-based professional 3D CAD software. For professional use, you need to pay a monthly subscription but It also offers free licenses for personal use, students, educators, and startups.

Fusion 360 uses parametric modeling but u can change it to direct modeling when it is convenient for your project. SketchUp is better suited for beginners or intermediate users focused on construction and interior design while Fusion 360 features and tools make it more appealing to a wider audience.

With SketchUp, 3D modeling is made simple as it has a narrower focus making it easier to use than Fusion 360, In addition, Sketchup’s paid versions are cheaper than Fusion360’s subscriptions. SketchUp may demonstrate to be a faster option to get started with small projects, but if you are looking to create complex technical designs down the road, give Fusion 360 a try.

Fusion360 is my favorite designing program available, so I might be a little biased in the review I wrote about it.

SketchUp vs AutoCAD

AutoCAD is a precise 2D and 3D drafting software and was one of the first CAD programs introduced in 1982. There is no free version so you need to pay a monthly/annual subscription in order to use it.

Even though AutoCAD is ideal for 2D drafting it isn’t very user-friendly to use in complex 3D modeling as it has a steeper learning curve than most CAD software. Because of that, it is not a very popular option in the 3D printing community.

Because AutoCAD subscriptions are expensive, SketchUp is a better option for most hobbyists to design their models. AutoCAD is rather used by professionals working on industry-level designs.

Frequently asked questions

Do I have to download SketchUp?

SketchUp has both a desktop and a web-based version. The Free and Shop plans only allow for web-based use of the software, whereas the Pro and Studio subscriptions offer web and desktop usage, meaning that you can download the software and use it offline.

How much does SketchUp cost?

SketchUp offers a free version, and for those who want to check the features from the paid versions, there is a 30-day trial, after which you would have to pay for a subscription or go back to the free version. You can expect to pay around $10 to $30 per month for the Shop and Pro versions, whereas the Studio subscription will set you back around $100 per month.

Can you render objects with SketchUp?

There aren’t any native rendering tools in SketchUp that allow you to create photorealistic images of your models. However, there is rendering software that you can use in conjunction with SketchUp to get the results that you want. You can use rendering extensions that run inside SketchUp or rendering apps that work outside SketchUp as standalone apps.

What operating systems does SketchUp support?

For the web-only version, you just need an internet connection to use SketchUp, and the desktop versions are being developed and maintained for Mac and Windows operating systems. Although it is possible to install Sketchup on Linux, it is not supported by the developers.

Can you export STL files in SketchUp?

SketchUp supports imports and exports in STL format, which is the most common file type in 3D printing. In order for your model to become a successful print, you need it to meet some requirements before exporting the file like having a base, a volume, and being a solid group.

Can I activate my SketchUp Pro license on more than one computer?

If you possess a classic license you can activate your SketchUp license on up to 2 computers and for subscription users, you are allowed to sign in with 3 computers.

Conclusion

Having gone through most of the key features that make Sketchup a popular choice among designers, we can definitely conclude that it is a viable option for getting started in the 3d modeling world.

Having said that, there are other intuitive and friendly programs out there that are also better suited for professional uses if you choose to do so in the future. Such is the case of Fusion360, which is also free in most cases, and I definitely urge you to consider it.

We created a recommended products section that will allow you to remove the guesswork and reduce the time spent researching what printer, filament, or upgrades to get, since we know that this can be a very daunting task and which generally leads to a lot of confusion.

We have selected just a handful of 3D printers that we consider to be good for beginners as well as intermediates, and even experts, making the decision easier, and the filaments, as well as the upgrades listed, were all tested by us and carefully selected, so you know that whichever one you choose will work as intended.

creating figures, models, how to make sketches stl file, draw a detail

Before creating any product on a 3D printer, you will first need to make a digital sketch of it. To do this, you should develop a model or layout of the product in a specialized program. Consider which 3D models are most popular for layer-by-layer printing, the nuances and step-by-step instructions for their creation.

What are 3D printer sketches and why are they needed?

Sketches (also have the name of the model, layouts, blanks) for a 3D printer are digital files made in STL format using specialized programs. They schematically describe the geometry of the surface of a three-dimensional object, without taking into account its texture and color.

To print an STL sketch, you will need the 3D printer control code compiled by the slicer. In simple terms, the model will need to be pre-cut in the slicer program into layers that will be sequentially printed by the printer. Typically, such a file has a gcode extension.

Which layouts are in demand?

3D printing is a versatile tool that can be used to print a wide variety of products. Most often, ten types of layouts are used to create various types of products:

Auto parts - plastic washer nozzles, latches, plugs, fasteners, manifolds and other expensive or scarce parts.
Souvenir products - caskets, figurines, figurines, emblems, badges, pens, key chains, covers, toys, icons, jewelry, game sets (checkers, chess, backgammon), coasters and organizers.
Personal protective equipment - plastic face shield, disposable mask clip, hands-free door opener.
Educational and advertising layouts for visual display.
Surgical and dental models of bones, organs, teeth, prostheses.
Fishing products - reels, nods of various thicknesses and stiffness, sequins for tying flies.
Holders for phones, cups, cameras and other items for bicycles or car interiors.
Accessories and decorative elements for clothing.
Parts for household appliances - handles for washing machines, microwave ovens and various kitchen utensils, plastic control buttons, small plastic parts from blenders, coffee makers and kettles.
Musical instruments (guitars, flutes, violins, drums, pianos, banjos) and parts for them.

How to make a drawing yourself?

A drawing to create a 3D product on a printer must first be made schematically, and then transferred as a three-dimensional model to a special 3D modeling program. A schematic drawing of an object with a display of all sizes and spatial arrangement is performed on a sheet of paper using measuring tools (ruler, compass, caliper).

What programs are needed to create a model?

You can create a 3D model using a full featured 3D modeling editor. Here is a short list of the most convenient programs for work:

Free - Blender, Sculptris, Daz Studio, Softimage Mod Tool, Vue, OpenSCAD, FreeCAD, TinkerCAD.
Paid - AutoCad, Houdini, 3DS Max, Cinema 4D, Meshmixer, Modo, SolidWorks, Sculptris, Maya, Rhinoceros, 3D, ZBrush, SketchUp.

Preparatory steps

For the convenience of working in any of the 3D modeling programs, it is recommended that the user first set up the working environment for layouts for 3D printers.

Then, in the units of measurement settings block, you should set the metric system of measurements and set the scale. After that, you can start creating the object.

Creating a 3D object

The steps involved in creating a 3D layout directly will depend on the functionality of the program being used. If we consider the process in general, without being tied to a specific editor, then the creation of an object will be performed in the following order:0003

Selection of model appearance options. At this stage, one of the templates preinstalled in the program can be taken as a basis.
After adding a shape to the workspace, you can use levers and various modifiers (extrusions, roundings, indentations) that will make the model unique.
In parallel with the creation of the model, its dimensions and dimensions of individual parts should be adjusted.
The final step is choosing colors and textures for the shape.

Checking the design against the general guidelines

Before finalizing the creation of a 3D object, consider the most important aspects that will affect the quality of the finished product and optimize the project. For correct printing of the model on a 3D printer, it is recommended that the surfaces of the figure in the project do not overlap. This should not be allowed, as a failure may occur during printing, which will lead to problems with the quality of the figure itself. Therefore, all surfaces of a three-dimensional object should only touch, forming a single model.

Exporting a project

Exporting a finished project in STL format is the final step in preparing a 3D model for printing. It is carried out in the following order:

In the "File" tab menu, select the item "Export", "Save as ..." or "Save project"
or removable media.
After saving the project, it is transferred to a USB flash drive or SD card that can be inserted into a printer, or printed directly from a computer if it is connected to a 3D printer.

What to consider in order to create a 3D model without errors?

You can prevent defective or inferior parts from printing when creating a 3D model. To do this, you should take into account the most common user errors in the process of creating a layout, such as:

Lack of support.
Creates elements that are too thin.

Adding support

When creating a complex 3D object with multiple transitions, be sure to provide supports (supports) in the project that will support the parts of the model hanging in the air. The supports are printed with the model and can be easily removed after printing is complete.

Wall thickness and hole diameter

The lines created in the project should not be too thin. Since elements that are very tiny in thickness can turn out to be very fragile or not printed due to the characteristics of the extruder nozzle.

When using an FDM printer for printing, it is recommended to simulate the walls of objects with a thickness that is equal to at least two diameters of the printer's extruder nozzle. When printing on a photopolymer 3D printer, the thickness of the thinnest part should not exceed 0.5 mm.

Therefore, if there are thin parts, it is worth getting rid of them. And if this is not possible, then you should either increase them or add support.

Creating a 3D sketch, drawing or model for 3D printing is an easy process that you can learn on your own. To print simple objects, you will need to learn the basics of 3D modeling, which will be easy to reflect on a specific printer.
