How Good Should be Your Computer for 3D Printing?

Overview of Using Computer for 3D Printing

This is a question where a lot of hype is happening in the 3D Printing world. Most of the time, it is falsely said that 3D printing needs a powerful 3D computer / Laptop with more processing power.

Don’t be panic! if your computer / laptop is bought recently in the past five years with a basic configuration, then that would do. Go ahead and start 3D printing and get your hands dirty.

In some cases, a more advanced computer can be an added benefit, while it is not needed if you want to run simple models and prints.

1. How Powerful Should Your Computer be for 3D Printing?

3D Printing doesn’t need a powerful computer, in most of the cases a basic Laptop / PC would be enough. Even Slicing (G-code) can be done on basic machines that are with you.

Most of the 3D enthusiasts use basic computers to store 3D models and Slice (G-code) them for 3D printing. But those users who want to model objects need powerful computers.

Basic Computer requirements for 3d printing

ProcessorDual Core / Core 2 Duo/ i3
Ram4GB / 8GB
Graphics CardNot necessary
Hard Drive512GB

Many times, a basic computer with Intel / AMD Dual core processor and 4GB RAM should be ample enough to run the Slicer for smaller / simple objects. It may get slow for large and complex objects.

An Ultimaker Cura Slicer is the best example that can run with minimal hardware requirements such as 4Gb RAM, Normal Single core processor and 5 GB Hard drive space. This is the same with other slicers like Prusaslicer and Simplify3D. Aim for a higher configuration than mentioned by developers to avoid delays.

Here’s such an example with minimal configuration also known as a business PC.

2. Best Computers/Laptops for 3D Printing

When it comes to desktop, the suggested model would be Dell Inspiron 3471 from Amazon. This is powered by intel core i5 9th generation processor with 12 GB RAM and 128GB SSD.Amazon). 

This configuration is very ideal for the smooth operation of a 3D printer and also helps in designing and 3D modeling.

When it comes to Laptop, the ideal go to device would be Dell Latitude E5470 HD from Amazon. This has a core i5 processor with a clock frequency of 3Ghz.

It’s all dependent on the kind of designs you want to process. For Hi-poly designs and slicing 3D files for a complex model demands high configuration computer /laptop such as 5Ghz Processor Clock Frequency, GTX 960 Graphics card, 12 to 16GB RAM.etc

The computer / laptop configuration is purely dependent on the complexity of the models you want to execute and print.

If you are seriously looking for a really fast system, then Acer Nitro 5 AN517-54-79L1 Gaming Laptop would do the job. It has Intel Core i7-11800H processor,  NVIDIA GeForce RTX 3050 Ti Graphics Card, 16GB DDR4 and huge 1TB NVMe SSD that can handle any complex design and execution.

For achieving process synchronization with the 3D printer, gaming desktop would be ideal because of their high configuration.

If you are looking for a powerful laptop for 3D printing, MSI GS75 Stealth Gaming Laptop is a go to device. It has Intel Core i7-10875H, 16GB RAM, 512GB NVMe SSD, NVIDIA GeForce RTX 2060 Graphic card.

The NVIDIA GeForce RTX 2060 Graphic card can help in rendering the 3D designing and modeling at its best. Slicing of the complex model wouldn’t be a problem at all on this device.

Desktops are more suitable for 3D printing than Laptops as their processing capability is good

Another safer way to avoid print failure and reduce the computer dependency while printing is to load the 3D sliced model onto SD Card and insert into the 3D printer. This keeps the printer running even if the computer goes into sleep mode.

In conclusion, 3D printing doesn’t need a high end and powerful Computer / Laptop, instead a recent model which you have bought in the last 3 years would do. On the contrary, if you want to process 3D models with complex shapes you need a high configuration computer.

3. How Does File How Good should be your Computer for 3D Modeling?

When you want to use 3D CAD modeling software, a computer / Laptop High-end configuration is a must. These modeling softwares are process heavy, demanding an advanced hardware ecosystem for their execution. The processes tied with these software programs are complex and need parallel execution for better response and real-time feeling.

If your designs are simple, a low configuration would work. But when designs get complex, they get heavy and fight for resources on the computer.

If you are a beginner trying to experiment with simple object models, a basic laptop or PC should work. An upgrade is needed as you get working with complex models.

Computer Configuration for 3D CAD modelling

ProcessorIntel core i5 10th gen / i7 6th gen processor
Ram16GB DDR4
Graphics CardNVIDIA 3050Ti

As 3D CAD modeling is heavy software, you need to look for a PC / Laptop with at least 16GB RAM, Core i5,i7 / AMD Ryzen Series processor, NVIDIA 3050 Graphics card with 512GB SSD. This configuration would serve even the advanced users producing complex 3D models.

There is no hard and fast rule about the computer hardware configuration. It varies based on the usage capabilities. You may look for different configurations as per the need. My goal is to shed a light on the minimal configurations needed for seamless operations.

Here’s a 3D Gaming computer with 3D modeling capabilities with advanced hardware.

4. Processing 3D Prints Using a Laptop

When using Laptop for sending printing data to a 3D printer may cause the printer to stop and start at random intervals. This is because the Laptop sends the data in chunks.

One way to avoid this is to ensure that the laptop doesn’t get into sleep mode or log-off state and keep it always active and running.

Usage of computers is a better option than a laptop as they send data continuously in a smoother format. This keeps the 3D printer always in sync with Computer.

We can also make use of SD card in order to reduce the connectivity issues between Laptop/Computer and 3D Printer. This SD Card can be loaded with a 3D model print file and inserted directly onto your 3D printer slot. This ensures the printing without interruption.

4.1 Minimal Hardware configuration needed:

  • Hard Drive Space: Windows 7 or higher (64-bit) with 30GB free disk space. Usually SSD is preferred because of its fast data transfers.
  • Graphics Card: NVIDIA 1650/3050 with 1 GB built in memory or more
  • Processor: intel i3/i5/i7/AMD Ryzen above 2.2 GHz clock speed with generation between 7th to 10th for intel processors.

4.2 Software Needs:

  • Operating System: Windows 7/8/10 with 64-bit versions.
  • Network: Ethernet / Wi-Fi
