Easter 3D Printing - Highlights

Easter is a great time to make some cool Easter 3D printables that show off your Easter 3D printing skills. There are many 3D mockups on the Internet that you can download for free: classic painted eggs, candy dispensers or bunny decorations. Craftcloud and global service partners help those with little time or the right equipment to print selected objects to order in colors and from materials of their choice.

For those who like to surprise their friends for the holidays, the 3D industry offers a selection of original Easter prints.

Dispensers & figurines category

Everyone loves candies and toys, so this group is the most saturated - from chocolate dispensers to bunny key chains - printed products will easily make the holiday bright and cheerful.

Rotating Egg Dispenser

This Easter decoration has a trick up its sleeve - this beautifully shaped item can dispense chocolate treats. Children and chocolate lovers will certainly appreciate the original presentation of sweets.

Since the two separate parts of the dispenser must be printed at the same time, you need to "grow" the model relatively slowly to keep the egg spinning. The STL model already includes a small support ring on the base that can be easily removed after printing. Zooming out can cause the two walls to merge during printing, but scaling up will not cause problems. And the increased size means there will be more room for chocolate!

Bunny Puzzle

This simple bunny puzzle is amazing as a fun toy for kids or a cute Easter decoration to place on the table. It should be simple and fun to 3D print. When printing, it is recommended that all parts, including those located on the sides, be placed separately to avoid accidental sticking together. Printing little rabbits in different colors looks great!

Bunny Chocolate Dispenser

More ways to hide chocolate around the house is a good thing! The bunny-shaped chocolate egg dispenser is another great Easter toy.

Flexi Rabbit

Flexi Rabbit is the cousin of the popular character Flexi Rex. The model contains 10 hinges located along the body, which allows the figure to bend and unbend. This themed toy is suitable for all ages. It must be printed slowly so that the seams do not melt. For making a rabbit, PLA plastic works best.

Egg holder

This chocolate holder is simple yet fun. Everyone will love this cute bunny whose body is made from a delicious chocolate egg. Models can be hidden during an Easter egg hunt, used as a fun surprise in a holiday basket, or simply hung around the house for guests to grab a bite to eat.

This is another bunny variation that is best printed on the side. Because it's a fairly simple object, it prints without too much trouble. The main thing is to correctly scale the layout so that it matches the size of the chocolate eggs.

Egg category

What's Easter without the classic Easter egg? Printed samples can be used as your imagination suggests - put chocolate inside or decorate your house with them.

Adorable Dozen

All 12 of these beautiful designs are unique and fun. From strict geometric patterns to stylish waves, there is a pattern for every taste. These eggs add the perfect finishing touch to your Easter dinner table.

Persons (Persons)

These eggs are sure to add some personality to the Easter fun. Not only are they creative and cute, but they are also very easy to make for beginners and don't require maintenance or complicated techniques to get great results. These unique eggs have silly faces, so everyone can choose which one suits their family best.

Decorative boxes

These pretty eggs are sure to grab attention. Each copy is printed in the form of two halves, so it is convenient to use them as a small gift box. Products can be printed in different colors, mixing or combining different contrasts to make the decorations even brighter. The boxes were originally printed in ABS filament, but they will be just as successful in PETG or PLA.

Colorful Samples

Although these eggs cannot be filled, they are an interesting decoration and can be printed in multiple pieces to create fun color combinations and patterns. Such models are easy to print, they do not need supports. It is worth printing at least two eggs so that you can experiment by changing the elements.

Patterned

Every year, designers come up with new patterns that look great in any color. Small details make the eggs a stylish addition to your Easter decor. They are also easy to make and do not require special supports. Most users have printed them in PLA, but prints also work well in ABS or PETG.

Jewelry category

To get the coolest decorations for Easter, you can use Easter 3D printing samples that are sure to capture the festive spirit. These seasonal 3D models can also make great gifts.

Ducky Bunny

This cute bunny is sure to arouse the envy of guests, so its only drawback is the need to print a lot of copies in order to give them to everyone. Ear and chin supports are required for optimal results when printing a Ducky Bunny. It is recommended to use an increase in the area of the substrate, since the base is not so large and can potentially deform. Most users prefer to print this model in PLA.

Crow's Nest

Easter 3D printing will help you make unusual coasters for beautiful 3D printed eggs. The original decor in the form of an openwork nest will look great, no matter what you put in it. Even after the holiday is over, it is convenient to use it as a key holder or fruit bowl.

Although not the easiest model to print, the object looks great and is well worth the effort. It is important to make sure that the adhesion to the table is sufficient, otherwise printing problems will occur. You can add a few carefully crafted supports, but don't overdo it, as removing them from this fragile structure can be a daunting task.

Cookie cutters

Easter Seal allows you to not only bake a delicious treat, but also celebrate Easter by eating a cookie in the shape of a rabbit! Dough molds are very easy to 3D print using food-safe PLA plastic.

Candlestick

This egg-shaped basket is festive and useful. The print is designed as a decorative candle holder, but it is also suitable for filling with candies and other Easter surprises. As a decor, it is necessary to use an LED flashlight so as not to accidentally melt the plastic.

This is a large 3D model and may take some time to print. The small footprint means that using fields or rafts is a good idea.

Stanford Bunny

Stanford has updated Easter merchandise in a stunning new way based on Voronoi (Thyssen, Delphiel) polygons. You can even print a friend to the rabbit - a cute lop-eared Bunny Ducky.

When working with these models, supports should be placed carefully so that they do not damage the fragile model. It is also important to type at a slow speed.

Scientists have figured out how to print a fully finished robot on a 3D printer

Elizabeth Console news editor

A team at CU Boulder has figured out how to combine the printing of solid and liquid components on a 3D printer to make a complete robot.

Read Hi-Tech at

The authors of the new paper believe that by mixing solids and liquids, 3D printers can create devices that are more flexible, dynamic and useful. For example, you can print wearable electronic devices with wires or even models that mimic the softness of real human organs.

I think we can create a complete system, like a robot, using this process.

Robert McCurdy, senior author of the study and Paul M. Ready Associate Professor of Mechanical Engineering

The authors believe that their idea is similar to the transition from black and white printing to color. Color printers combine a small number of primary colors to create a huge palette. The same works for different materials. If you have a printer that uses multiple materials, you can combine them in new ways and create a much wider range of mechanical properties, notes McCurdy.

Conventional printers create an image by applying liquid ink using thousands of dots. Inkjet 3D printers, by contrast, use a printhead to apply tiny droplets of liquid called voxels. After that, the voxels settle and harden.

But, according to the authors, there are cases when it is necessary to leave the substance liquid. Some engineers, for example, use liquids or wax to create tiny channels in solid materials that they then empty at a later stage. It is similar to how drops of water form underground passages and caves.

The authors of the new work figured out how to create the same empty spaces in parts printed on a 3D printer. They first developed a series of computer simulations to explore how printing different kinds of materials work next to each other.

According to McCurdy, one of the big challenges is how to prevent droplets of solid materials from mixing with liquid materials, even if the droplets of solid material are printed directly on top of the liquid droplets.
