Rolohaun Delta Flyer Review: Budget Delta 3D Printer Kit

---

1. Introduction to Rolohaun Delta Flyer

If you’ve been searching for a budget delta 3D printer that doesn’t compromise too much on quality, the Rolohaun Delta Flyer might just be the printer you’ve been waiting for. In a market flooded with boxy Cartesian machines, the Delta Flyer stands out with its elegant triangular frame, lightning-fast print speeds, and an entry price that won’t leave your wallet crying for mercy.

The Rolohaun Delta Flyer is a delta 3D printer kit designed with accessibility in mind. Whether you’re a curious hobbyist dipping your toes into additive manufacturing for the first time, or a maker looking to add a nimble, compact machine to your workshop, this kit positions itself as a compelling option. It ships as a build-it-yourself package, which means you get to learn the mechanics of your machine as you put it together — a rewarding experience that many 3D printing enthusiasts swear by.

In this review, we’ll walk through everything you need to know: what makes delta printers special, how the Delta Flyer is built, how easy it is to assemble, how well it actually prints, and whether it’s the right machine for you. Let’s dive in.

2. What Is a Delta 3D Printer Kit?

Before we talk specifics about the Rolohaun Delta Flyer, it helps to understand what a delta 3D printer kit actually is — and why delta kinematics are so interesting compared to the more common Cartesian design.

Most entry-level printers you’ll encounter use a Cartesian motion system: the print head moves along X and Y axes, while the bed moves along the Z axis (or vice versa). It’s straightforward, predictable, and easy to calibrate.

A DIY delta 3D printer, on the other hand, operates on a completely different principle. Three vertical towers are arranged in a triangle, and the print head is suspended between them using a set of diagonal arms. All three motors work in coordinated concert to move the effector (the part that holds the hotend) in any direction. The math behind it is more complex, but the result is impressive: delta printers can move very fast with minimal vibration, since the effector itself is extremely lightweight.

Here’s a quick comparison to help frame things:

Feature	Cartesian Printer	Delta Printer
Motion System	X/Y/Z axes independently	3 coordinated vertical towers
Print Speed	Moderate	High (lightweight effector)
Build Volume Shape	Rectangular	Cylindrical
Footprint	Wide / Spread out	Compact / Vertical
Calibration Complexity	Simpler	More involved
Best For	General use	Speed, tall objects

The delta design is particularly well-suited for printing tall, slender objects — think vases, figurines, or architectural models — because the cylindrical build volume offers generous vertical height. And because the effector is so light, deltas can achieve impressive speeds without the print quality degrading significantly from vibration.

3. Design & Build Quality

One of the first things you’ll notice about the Rolohaun Delta Flyer is how elegantly minimal it looks. This is a compact delta 3D printer in the truest sense: three slender vertical rails rise from a triangular base, connected at the top by a compact upper frame. The whole machine occupies a remarkably small horizontal footprint compared to most Cartesian printers of a similar build volume.

The small footprint 3D printer advantage becomes very real when you actually place it on a desk. Unlike typical bed-slingers that need room for the build plate to travel back and forth, the Delta Flyer just sits there in its neat triangle, doing its thing vertically. This makes it a fantastic choice for apartments, small workshops, classrooms, or any environment where desk space is precious.

The frame itself is constructed from aluminum extrusion profiles, which is the standard for quality budget machines. Aluminum extrusion is rigid, lightweight, and modular — it can be tightened, adjusted, and upgraded over time. The diagonal arms connecting the carriages to the effector are typically made from a combination of carbon fiber rods and printed or injection-molded joints, keeping the moving mass to an absolute minimum.

The overall impression is one of purposeful engineering. Nothing feels gratuitously cheap. That said, at this price point, you won’t find premium machined aluminum everywhere — some brackets and connectors are made from printed plastic, which is entirely reasonable and common across the budget delta segment.

4. Assembly Experience

Here’s where things get genuinely interesting — and potentially intimidating, depending on your experience level. The Rolohaun Delta Flyer ships as a beginner 3D printer kit, but let’s be honest: delta printer assembly is a step up in complexity compared to putting together a standard Cartesian kit.

That said, “more complex” doesn’t mean “impossible.” Far from it.

Following the included delta printer assembly guide, most builders report completing the assembly in somewhere between 4 to 8 hours, depending on how methodical they are and how much time they spend reading ahead before picking up a screwdriver. The documentation covers the mechanical assembly, wiring, and initial firmware configuration.

Here’s roughly what the assembly process looks like:

Stage	Task	Est. Time
1	Frame assembly (base + towers + top)	1.5 – 2 hrs
2	Carriage & arm installation	1 – 1.5 hrs
3	Effector & hotend assembly	30 – 45 min
4	Electronics & wiring	1 – 1.5 hrs
5	Firmware upload & calibration	1 – 2 hrs

The calibration stage deserves special mention. Delta printers require delta-specific calibration — instead of simply leveling a flat bed along two or four corners, you’re working with a process called delta calibration, which accounts for the geometry of all three towers simultaneously. Modern delta firmware (typically Marlin or Klipper-based) includes auto-calibration routines that probe the bed at multiple points and compute corrections automatically. Once you understand what’s happening, it becomes much less mystifying.

A word of advice for first-timers: take your time on wiring. Label your connectors, follow the wiring diagram carefully, and double-check polarity before powering on. This single habit will save you hours of troubleshooting.

5. Performance & Print Quality

Once you’ve got the Delta Flyer up and running and calibrated, you’re in for a treat. As an entry level delta printer, it punches notably above its weight class in terms of print speed.

Delta kinematics allow the machine to achieve print speeds that would shake a similarly priced Cartesian printer into producing spaghetti. The Delta Flyer is comfortable running at speeds that keep quality consistent and clean, making it ideal for prototyping, small production runs, or simply enjoying faster print times on your hobby projects.

Print quality at standard settings — typically 0.2mm layer height, moderate speed — is solid and clean. Overhangs and bridging perform well thanks to the consistent, vibration-dampened motion. The cylindrical build volume is well-suited for:

• Tall decorative objects (vases, sculptures, architectural models)
• Functional prototypes with vertical features
• Figurines and miniatures where fine detail matters
• Cylindrical or round objects that take advantage of the build area shape

In terms of compatible materials, the Delta Flyer handles the standard range you’d expect at this level:

Material	Supported	Notes
PLA	✅ Yes	Primary recommended material
PETG	✅ Yes	Reduce speed slightly
TPU (flexible)	⚠️ Limited	Depends on extruder type
ABS	⚠️ Possible	Enclosure recommended
Wood / Silk PLA	✅ Yes	Great visual results

PLA is the star material here, and the Delta Flyer handles it beautifully. PETG works well with a slight reduction in speed. ABS is possible in a stable, draft-free environment, though an enclosure would significantly improve results.

6. Key Features Overview

Let’s break down what’s actually inside the box when you pick up an affordable 3D printer kit like the Rolohaun Delta Flyer.

Feature Category	Specification / Detail
Frame	Aluminum extrusion, triangular delta configuration
Motion System	Linear rail / smooth rod delta kinematics
Effector Arms	Carbon fiber diagonal rods (lightweight)
Hotend	Standard E3D-style all-metal or PTFE-lined hotend
Extruder	Bowden-style remote extruder
Control Board	32-bit or 8-bit board with delta firmware support
Display	LCD or TFT touchscreen (varies by configuration)
Connectivity	SD card / USB
Bed Surface	Round heated or non-heated build plate
Filament Diameter	1.75mm standard
Firmware	Marlin-compatible (open source)

The Bowden extruder setup is well-chosen for a delta printer: keeping the heavy extruder motor fixed on the frame rather than moving with the effector is key to maintaining that lightweight, fast-moving print head that deltas are celebrated for.

The open-source firmware compatibility is a big plus. Marlin is one of the most widely supported 3D printer firmware platforms in existence, meaning a vast community of users, extensive documentation, and almost unlimited tuning potential.

7. Pros and Cons

No review is complete without an honest look at both sides. As a low cost 3D printer kit, the Rolohaun Delta Flyer has genuine strengths — and some areas where budget constraints show up.

✅ Pros	❌ Cons
Very compact horizontal footprint	Delta calibration has a learning curve
Impressive print speeds for the price	Cylindrical build volume limits rectangular prints
Lightweight effector = smooth fast motion	Bowden extruder can cause issues with flexibles
Great for tall prints	Some plastic brackets in the structure
Affordable entry price	Documentation could be more beginner-friendly
Open-source firmware (Marlin)	Community support less than big brands
Educational assembly experience	Not ideal for pure beginners with zero experience
Compatible with standard 1.75mm filament	Heated bed may be optional/add-on cost

The cons here are largely inherent to the delta printer format and budget category rather than specific failings of the Rolohaun brand. Delta printers will always demand a bit more patience and technical engagement than a pre-assembled Cartesian machine. If you’re willing to invest that effort, the rewards are real.

9. Who Should Buy the Rolohaun Delta Flyer?

This is perhaps the most important question of the whole review. A printer is only as good as it is for the person using it. So who is the Rolohaun Delta Flyer actually for?

It’s a great match for:

The curious beginner with a technical streak. If you’re new to 3D printing but you’re not afraid of reading documentation, watching tutorial videos, and spending a weekend putting something together, this is an excellent choice. As a beginner 3D printer kit that teaches you the mechanics of a delta machine while you build it, the educational value is genuinely high. You’ll understand your printer deeply by the time it’s running.

The maker or hobbyist who’s already done Cartesian. If you already own or have used a standard bed-slinger and you want to explore delta kinematics, the Delta Flyer is a low-cost, low-risk way to do exactly that. It’s a great DIY delta 3D printer project for a weekend.

The space-constrained creator. If your workspace is limited — a small apartment, a shared studio, a corner desk — the Delta Flyer’s tiny horizontal footprint is a genuine quality-of-life improvement over most other printers.

The tall-print enthusiast. If your typical projects involve vases, towers, figurines, or other vertically oriented objects, delta geometry is naturally better suited for your work.

It may not be right for:

• Complete beginners who want a plug-and-play experience with zero assembly.
• Users who need large rectangular prints — the cylindrical build volume doesn’t accommodate wide flat objects efficiently.
• Those printing lots of flexible filament — the Bowden setup isn’t ideal for TPU.
• Users needing strong brand support — if you prefer a large established company with dedicated English-language customer service and a huge user forum, you may find the community around this brand smaller than giants like Creality or Bambu.
