Dimensional accuracy refers to the precision with which dimensions are measured. In this post, we’ll look at the dimensional accuracy of 3D printed objects. Is it up to par? And what can you do to make it better? But first, what is the significance of dimensional accuracy? In fact, it is negligible for many models. You won’t be hauling out the calipers to assure a tolerance of 1 Angstrom if you merely need something for pleasure or adornment. High dimensional accuracy, on the other hand, is required if you need precise parts to be interoperable with other hardware, for example. Here are four tips for improving dimensional accuracy in 3D printing!

Check Your Printer’s Accuracy

Find out how accurate your printer is printing before you start adjusting belts and tweaking software. To this aim, there are a variety of useful test prints available, with calibration cubes being particularly beneficial. Remember that positive dimensional inaccuracies are usually preferable to negative ones. It’s possible to sand prints down to size, but it’s far more difficult to add material once they’ve been printed!

Check Working Units

Before anything else, double-check that you’re using the correct units. You’ll notice some discouragingly big or little prints if your 3D model utilizes one unit and your slicer uses another. As a result, make sure you’re only working in one unit of measurement before moving on to the next quick repair.

Tension Belts

Check your printer’s belts. Dimensional errors can be caused by both loose and overly tight belts. Almost every printer employs a distinct method of belt tensioning. Tighten your belts, regardless of printer type, so that the drive gears do not slip and the belts resonate like a guitar when plucked. If you’re having problems tightening belts, try your best and then print a belt tensioner to complete the task. Clothespin springs are also quite effective!

Check Linear Movements Components

What are the proper working units? Check! Are your belts cinched? Check! If the dimensional discrepancy persists, double-check that the linear rods, rails, and screws are all straight! It is impossible to move them accurately if they are bent. Replace any bent pieces with new ones and repeat the test print. Try lightly oiling the linear rods and screws if everything is exactly straight. A small amount of lubricant can go a long way!
