TPU 3D Prints: 30 Useful Designs Only Possible with Flexible Materials
Ready to make your own flexible TPU prints? Check out our list of cool things you can 3D print with TPU and other flexible filaments!
Not so long ago, flexible filament was considered the ultimate challenge in desktop FDM printing. Clogged nozzles, extruder jams, and wasted material were common when printing with flexible materials. With the latest generation of 3D printers featuring excellent direct-drive extruders, printing TPU and other thermoplastic materials (TPE) has become way more accessible.
This means we are seeing a massive trend toward functional applications, such as shoes and slippers, or airless balls and tires, which took the file repositories by storm, as well as custom-fit household gaskets, ergonomic grips, and even orthopedic aids.
In this article, we present a range of models that use the potential of flexible filament. If you’re new to TPU, scroll down to the end for some printer settings and handy tips.
+ Shoes
3D printed footwear has evolved from uncomfortable prototypes into stylish, breathable sneakers and slides. These may not yet rival commercial brands, but here at All3DP, we wear ours around the office. By leveraging flexible TPU and clever lattice geometries, makers can now create shoes that offer genuine cushioning and support without the need for foam or glue.
Before you start the days of printing shoes take, test print a quick pare in PLA to measure for “approximate” size and make sure you like the styling.
3D printing the popular Crocs shoes may be a fun way to put your printer to the test and compare them to the original, but one thing to keep in mind when printing shoes is that some designs, such as Crocs and Air Jordans, are the patented intellectual property of their respective companies. There’s no legal cases that we can find of companies like Nike, Adidas, Crocks, or Birkenstock going after individual makers for downloading an STL printing out a pair, but we’re not going to feature branded shoes here.
Whaleberry Sport Shoes
If you’re looking for a shoe that balances sports aesthetics with everyday wearability, the “Whaleberry” is a good choice. Designed with a striking, generative thick sole and a streamlined upper inspired by marine forms, this slip-on shoe is sure to be a conversation starter.
Unlike simpler models, the Whaleberry is engineered for actual walking comfort, featuring a sole structure that effectively absorbs impact. It’s great for casual urban use. The designer has even included a nifty feature for customization: you can easily insert your own vector graphics (SVG) into the model using Bambu Studio to add a signature or logo directly onto the shoe.
The designer recommends TPU 90A for flexibility and structure, specifically Bambu Lab’s “Frozen” or “Blaze” for a nice gradient effect. Be prepared for a long print time – around 80 hours per pair – so ensure your filament is dry and your bed adhesion is solid.

Bambu Lab Presq Fig.(0)
Fig.(0) is an open-source footwear design released through a collaboration between Bambu Lab and Los Angeles–based design-tech studio Presq, aimed at making 3D-printed shoes accessible, customizable, and wearable for the broader maker community. The initial release includes ready-to-print files for a U.S. men’s size 10 along with a scaling coefficient table to adjust for other sizes, a pre-sliced .3mf file optimized for Bambu H2D printers using matte TPE 85A and PLA support material for a clean and functional finish, and the full CAD model that invites creators to remix and adapt the design with modular attachments, textures, and performance tweaks.
Every month, Presq will release a new design drop with fresh styles you can explore, print, and make your own.
Rather than keeping 3D printed footwear proprietary and closed, Bambu Lab and Presq explicitly designed Fig.(0) as a platform for experimentation and creative expression, giving designers, makers, and innovators practical tools to print their own shoes and tailor them to personal preferences. The collaboration signals a new direction in which digital fabrication and culturally resonant design converge, and it’s just the first of monthly open-source design drops intended to broaden participation in the future of footwear making.
Bambu Lab also has shoe collaborations with Formism

CityStep Casual Sneaker
If you think 3D printed shoes have to look like clunky plastic bricks, the CityStep sneaker is here to prove you wrong. This design mimics the look and feel of modern “knit” sneakers by using a clever slicer trick: The shell is printed with no solid outer walls and 100% infill. This creates a breathable, mesh-like structure that is surprisingly comfortable and flexible.
The shoe prints as a single piece, standing upright, which minimizes the need for complex internal supports. It features a structured heel and sidewalls to keep your foot secure, making it a viable option for actual daily wear.

Tongue Sandals
Sometimes 3D printing is about engineering, and sometimes it’s just about having a laugh. The “Tongue Sandals” (or “Lenguudos”) fall squarely into the latter category, but with surprisingly good execution. The concept is simple yet hilarious: the sandal is shaped like a monster’s mouth, and the front opening is positioned so that your own big toe protrudes to act as the “tongue.”
Designed by the creator of the popular dino-themed Triceracrocs, this model is optimized for Bambu Lab AMS (multi-material) systems, allowing you to print the eyes, teeth, and gums in different colors for maximum effect. Despite the joke factor, the sandal is a functional slide that can be worn for casual fun (or to embarrass your family).

Voronoi Slides
If standard “pool slides” feel too boring (or too sweaty), this remix is the perfect upgrade. Designer Tsandome has taken the classic slide silhouette and modified the upper strap with an organic Voronoi pattern. This not only gives the shoe a distinct, futuristic look but also significantly improves ventilation, making it ideal for hot summer days.
The model includes three pattern variations, with the designer noting that the first and third are easiest to print. It combines the stability of a solid sole with the flexibility of a mesh-like upper, creating a shoe that looks complex yet prints relatively easily.
For genuine comfort, 85A TPU (or softer) is highly recommended. Because the Voronoi pattern involves many overhangs and retractions, ensure your filament is perfectly dry to avoid stringing between the holes.

+ Personal Accessories
In this section, we’ve gathered a few common personal accessories that can be printed whenever you need them and customized to your liking.
Wavy Handbag
This chic “Wavy Handbag” proves that you don’t need complex assembly to create high-fashion accessories. The design features a distinct, undulating ripple pattern that looks like it belongs in a boutique window.
The genius of this model lies in its printing method: it is designed to be printed in Spiral Vase Mode using TPU 95A. This means the printer draws a single continuous line, spiraling upwards to create the bag’s body without any seams or retractions. This results in a print that is not only visually clean but also exceptionally fast to produce. The straps are printed separately and attached via simple pins, or you can opt for a longer shoulder strap using the additional files provided.
The designer strongly recommends TPU 95A and a 0.8mm nozzle (or setting your 0.4mm nozzle to extrude a 0.8mm line width) to ensure the single wall is thick enough to be durable.
- Who designed it? NoBeer
- How printable/popular is it? A rising star in the fashion category with nearly 800 likes. It’s a perfect “speed print” project for anyone wanting to test their large nozzle settings.

Massage Tools
This modular massage tool set features a handle with quick-swap TPU rollers designed for targeted relief across the back, legs, arms, stomach, and more. The rollers can also be used on their own for foot massage—simply place a roller on the floor and move your foot back and forth. A custom storage box keeps all components neatly organized, and four different interchangeable massage attachments highlight both the functional and aesthetic uniqueness of the design.
The project combines PLA for rigid parts and TPU for flexible rollers, with separate print sheets to simplify material setups. The large PLA storage case prints without supports, though some overhang areas may be a bit rough. TPU rollers require dialed-in settings for best results, so users should tune temperatures and retraction to match their own filament and printer. Thoughtfully engineered and refreshingly customizable, this set makes a practical, personal, and satisfying print for everyday recovery and relaxation.

Flexible Net Bag
This clever design leverages TPU’s exceptional durability and flexibility. Printed flat as a series of concentric cuts, the “Flexible TPU Net Bag” expands under gravity when you lift it, transforming a flat disc into a spacious mesh carrier. It’s an ingenious use of geometry that requires zero assembly.
The bag is robust, with the designer noting it can easily carry loads exceeding 670g (like a water bottle or heavy fruits). When not in use, it snaps back into its flat form, making it easy to store in a drawer or even another bag.
There are two main versions available: a simple one with dual handles (great for quick carrying) and a “drawstring” style with a denser mesh for smaller items.
- Who designed it? Tian
- How printable/popular is it? A highly practical print with nearly 5.0 stars. Users report it works surprisingly well even with PLA for lighter loads, though TPU is best for longevity.

Bracelet
The TPU Parametric Bracelet began as an experiment in whether soft TPU could bridge and hinge—and it turns out the answer is a definite yes. With flexible interlocking segments, the bracelet can be customized to fit your wrist by simply measuring and entering the desired length into the parametric model. Because the segment size stays constant, it’s recommended to add about 30 mm to your actual measurement for a comfortable fit, and to double-check the resulting length in your slicer before printing to make final adjustments.
Printed using Overture TPU, the bracelet benefits from TPU’s squishy, bendable behavior, but settings may vary with other filaments, so tweak profiles as needed for best performance. As always with TPU, a clean, grease-free build plate helps ensure good adhesion and consistent layer bonding. Fun to customize and surprisingly functional, this flexible accessory turns a material test into a wearable project.

+ How to Print Flexible Materials
Choose the Right Material
When purchasing a spool of TPU, the Shore hardness is your primary specification. This scale measures a material’s resistance to indentation – essentially, how “squishy” it is. The higher the number, the harder the material.
- The Sweet Spot (95A – 98A): Most standard TPUs sit in this range. They are roughly as hard as a shopping cart wheel or a rubber heel. This is the easiest flexible material to print with. Recommended for beginners.
- The Soft Stuff (60A – 85A): Filaments in this range feel more like a rubber band or soft shoe insole. While they offer superior flexibility, they are significantly more difficult to feed through the extruder and often require specialized setups.
You don’t always need a softer filament to get a softer part. By reducing your infill density and wall count (perimeters), you can make a “harder” 95A TPU feel surprisingly soft and pliable. Additionally, materials like VarioShore TPU alter their density and hardness based on the print temperature. For more information, refer to our guide on flexible materials.
Pick the Right Settings
A common myth is that you must completely disable retraction for flexible materials. This is true for older, Bowden-style printers, but modern direct-drive extruders handle retraction quite well. Disabling it entirely often leads to severe stringing (that “hairy” look).
Because TPU is elastic, it acts like a spring inside your extruder. If you pull it back too quickly or too far, it stretches rather than retracts, leading to inconsistent pressure or clogs.
Popular slicers switch to the appropriate settings when you select the right material profile. This is a good starting point for experimenting. These are the parameters you want to explore:
- Don’t turn retraction off, turn it down: Keep retraction distances short (e.g., 0.4 mm – 0.8 mm for Direct Drive) and speeds slow to avoid “yanking” the filament.
- Dry your filament: Often, what appears to be a retraction issue is actually moisture. Unfortunately, TPU absorbs water from the air. If your print looks fuzzy or you hear popping sounds, no amount of retraction tuning will fix it – you need to dry the filament first.
